the definitive guide to photograph it with your smartphone without ruining the camera

by

The experience of seeing a solar eclipse is something unique; given that, unless we decide to travel the world in search of itWe have very few opportunities in life. Therefore, it is not strange that everyone wants to photograph it. In the past, it was something that was only in the hands of a few scientists and astrophotography experts. However, with the widespread use of mobile phones, today we all carry a camera constantly in our pockets. It is the reason why many people will want photograph the solar eclipse this August 12 with their smartphones. It may seem like something simple. You take your cell phone, point it at the sky and take the photo. However, it is a much more complex process, requiring both security measures and basic knowledge about photography. And also, if possible, some gadgets that will make the process much easier. Therefore, if you are considering photographing the solar eclipse with your mobile phone, pay attention to this small guide. Maybe it’s not a good idea Before mentioning how you should photograph a solar eclipse with your mobile phone, it is important to keep in mind that most experts recommend don’t do it. Neither with the cell phone nor with a professional camera. The total eclipse on August 12 will last a couple of minutes at best. The longest eclipses in history They have not extended much beyond 7 minutesand yet they are scarce. They are usually very short.. Therefore, if we spend those few minutes behind the lens of a camera, we may not enjoy the experience. Experts often recommend enjoying the first eclipse by looking directly at it. Then, if you see more, you might consider taking photos. Now, if you are clear that images are going to be an important part of the experience for you, there is nothing wrong with taking them. As long as you do it with caution. The solar eclipse can damage your eyes and your phone! At this point, everyone (or almost everyone) We are clear about the importance of using approved glasses to look at the sun during a solar eclipse. However, we can make the mistake of thinking that if we look through a lens, our sight is protected. This is not true, in fact, if it expands our vision of the sun, it can also magnify the damage to our eyes. That’s why, it is important to use filters Suitable for the objectives and lenses of telescopes, cameras and binoculars. Now, if what we want is to photograph the solar eclipse with our mobile phone, our eyes are not in the same danger. If we look at the Sun on the mobile screen, there is no risk, since we are not looking directly through the lens and the screen does not emit a harmful glare. However, The image sensors of the mobile camera can deteriorate. This is because these cameras are prepared to take images of the sun in the background of a landscape or directly at times of weak lighting, such as sunrise or sunset. However, their sensors are not adapted to the illumination they receive when landing directly on the Sun at a time of higher illumination, especially if it is done for a long time. And of course, to take a good photo of the Sun, a good exposure is important. A quick click is not enough. Tips for photographing the solar eclipse with your mobile phone We have already seen that the first thing we must do to photograph the solar eclipse with our mobile phone is protect the camera. There are specific filterswhich are a very good option. Now, if we don’t want to spend money, we can opt for something more rudimentary, such as placing approved glasses directly in front of the lens. You can even cut one of the two lenses of glasses and glue it in front of the lens. The result will not be as good as with a specific fultro, but we will be able to get by. Most experts recommend that you just watch the eclipse, you don’t always have to take photos of everything Once the sensors are protected (and our eyes if we look through a lens), we must take into account the parameters at which it is best to take the photograph. From NASA recommend use a fixed aperture of f/8 to f/16 and try shutter speeds between 1/1000 and 1/4 second to find the optimal setting. That would be for the partial phases of the eclipse. On the other hand, during totality, the corona has a wide range of brightness, so they recommend using a fixed aperture and an exposure range that goes from approximately 1/1000 to 1 second. Of course, during totality the Sun is completely covered, so the camera filter can now be removed. It can and it should, since if we don’t do it we won’t see the solar corona well. However, the colleagues of Xataka Mobile They clarify that this is useful for cameras, but not for mobile phones. In case we are clear that we want to take the photo with our mobile phone, the best option is to do it automatically and follow some basic tips. Shoot at full resolution: Many current mobile phones have sensors of 50 and even 200 megapixels and manufacturers usually offer a shooting mode to take photos at maximum resolution. If your mobile phone has it, activate it since you will be able to have a huge image from which you can take a crop with very good quality Use optical zoom: Find out what the optical zoom of your mobile phone is and don’t go beyond that. If the maximum zoom is 3x, then shoot at 3x. This way you ensure that the quality will not worsen when using digital zoom. What are the best gadgets? We can try to see the eclipse directly and take photos at the same time. For this, it can be … Read more

Finding approved glasses to see the eclipse is more complex than it seems: here is a guide

by

The total solar eclipse on August 12 will be the first in peninsular Spain since 1912. However, many Spaniards have already seen the occasional partial eclipse. Although we are ashamed, many of us also have memories of having looked at the sun through an x-ray, in the absence of approved glasses. There were many myths about it and it used to be said that this measure was enough to protect the eyes. A very dangerous statement that left more than one person with sore eyes. Nowadays, luckily, there is much more information and we know that, to look directly at the sun, only glasses approved for eclipses are valid. The problem is that, as with everything, there will be people who try to profit by selling at a lower price some glasses that, in reality, do not meet adequate safety standards. Therefore, it is very important that we, as users, know what we should look at. Make sure they are approved. Approved glasses must contain the inscription: EN ISO 12312-2:2015. In addition, if you buy in the European Union, the CE marking must also be visible. On the other hand, there is certain information that must always be included: the name of the manufacturer, instructions on its safe use and conservation instructions. All of this should be included on the packaging or instructions. Make sure they are not broken. Your glasses may be approved and suitable for eclipses, but they may be damaged. If this is the case, they can be equally harmful to the eyes. That’s why, you should check that the filter is not scratched, loose or bent, and also that some areas are not lighter than others. In general, if you see any signs of deterioration in the area covering the eyes, you should look for others. Be careful where you buy. As long as all of these criteria are met, it doesn’t matter where you buy your eclipse glasses. However, it is true that if you buy them from planetariums, astronomical associations or scientific entities, they are more likely to be reliable. No, sunglasses don’t work. It may seem intuitive to us to wear sunglasses. After all, they are made to protect the eyes from solar radiation. However, direct and indirect solar radiation are not the same, especially when the direct radiation occurs under the conditions of an eclipse. Sunglasses meet their own safety criteria for protect us from scattered lightbut not to look directly at the king star. In fact, they can increase the risk, since they don’t block as much UV radiation as eclipse glasses, but enough so that we don’t have to squint. We will have them wide open and those radiations from which they do not protect us will be able to penetrate and affect us more. It doesn’t matter if 99% of the sun is covered. Even if there is only 1% of the sun visible, it is important to use approved glasses. The problem with eclipses is that, since there is a certain darkness, we do not blink or squint as much as we would when looking directly at the sun, so we do not have that perception of danger, but we do run the risk of damaging our retinas. Therefore, always check that your glasses are well approved. This way you can enjoy the eclipse safely.

We have been reading the Bible as a moral guide for centuries. More and more people use it for something else: looking for investment funds

by

When one puts your savings (many or few) in investment funds what you want are good returns. May your money generate more money. The question is… When pursuing this objective, can any criteria be applied beyond the strictly economic one? Is the search for profitability compatible with a moral approach? There are people who believe that the answer is ‘yes’ and that the financial sector must grow with an eye on environmental ethics or social, what happens, for example, by not supporting polluting companies. In that line, more and more people He decides to put his money in another type of investment funds: those that combine the search for profits with the morality of the Catholic Church. Investments and ethics? Exact. Although investment funds and exchange traded funds (ETF) are tools created to generate money, part of the financial sector has been trying to manage them with an ethical approach. Their idea is very simple: they offer returns, but with the guarantee that their analysts will be as attentive to the stock market as they are to the ESG criteria (Environmental, social and governance). That is, the idea is to bet on companies that in theory apply good practices and are respectful of the environment. What about religion? Among these ‘ethical’ funds, not all of them focus on respect for nature or human rights. There are those who emphasize the spiritual. His idea is that money generates profitability thanks to companies that conform to the precepts of a religion. Said this way, it may sound very abstract, but in practice it is very simple: investors avoid companies that make money through pornography, contraceptives, gambling, drugs, child exploitation, weapons, stem cell research… A clear example is the ‘Islamic EFT’funds that operate with sharia on the one hand, betting on companies that comply with the laws of the Koran. Does it happen with Christianity? Yes, too. In fact, just a few months ago, in februarythe Vatican Bank launched two stock indices that aim to make it easier for those who want to invest their money with a Catholic mentality. To be more precise, the Institute for the Opera of Religion (IOR) presented the Morningstar IOE Eurozone Catholic Principles and Morningstar IOR US Catholic Principles, a sort of S&P 500 and Euro Stoxx 50 ‘Vatican version’. “Both benchmarks are developed following best market practices and in accordance with Catholic ethical criteria. They are designed to serve as a reference for Catholic investments around the world,” explains the IOR. In the case of the European index are included for example, the banks Santander and BBVA, the technology company ASML or the luxury firm Hermes, while other multinationals with defense subsidiaries or presence in the alcohol market are relegated. In the case of the USA, Meta or Amazon appear. But… Do these funds move money? Yes. We know it thanks to a recent analysis of Five Days which confirms that Christian funds are strengthening their footprint globally. And clearly, too. The latest report from the consulting firm Brightlight shows that in the last five years alone they have doubled their assets, going from just over 58.5 billion dollars in the summer of 2020 to more than 115,700 million at the end of September 2025. If we look further back, funds based on Christian principles barely accumulated an asset of 16.5 billion in 2009 or 1,500 in 1990. What do they invest in? The increase in variable income assets stands out above all, followed by fixed income assets. In total Brightlight has identified 166 funds Christians, which is also double the number recorded in 2010. Such an increase is not explained only by the launch of the two indices of the IOR in February. Much earlier, in 2022, the Church already published Mensuram Bonama document with “a set of principles and criteria” aimed at the financial sector. “Investors are increasingly looking for benchmarks that reflect specific value- or policy-based criteria,” defend Morningstar. And how are they doing? Not bad. Although in general investment funds that are guided by ESG criteria have not gone through his best moment (last year they saw capital outflows worth more than $80 billion), the S&P 500 Catholic Values ​​Index has located above of the S&P 500 in recent years. Nothing surprising, moreover, if we see the list of companies on which it focuses. The growth of funds with a Christian focus can be explained, beyond the drift of the stock market, by their own characteristics. Some, for example, donate a part of their commissions to entities linked to the Church.

guide them to the exit one by one… with a surprise

In the late 80s, during the call “tanker war”the United States even escorted civilian ships in the Persian Gulf under flags changed in a hurryin an operation so delicate that any error could have triggered a direct conflict between powers. Even so, the simple transit of each ship became an almost surgical operation. A blocked strait that paralyzes half the planet. Since the start of the war in Iran, the Strait of Hormuz has become a critical bottleneck for the global economy. It is estimated that at this time there are around of 1,000 ships who remain trapped since the beginning of the conflict and about 20,000 sailors They remain on board with increasingly limited supplies. Not only that. The blockade imposed by Iran after the outbreak of war with the United States and Israel has reduced traffic at minimum levels and has stressed energy markets. The situation is such that analysts warn of a possible breaking point if the situation continues, since a fifth of the world’s oil normally circulates through this route. The US plan. In this scenario, Washington has launched the so-called as “Project Freedom” with an idea as direct as it is risky. Free trapped ships guiding them one by one outside the strait, yes, through coordination between countries, insurers and logistics operators. However, after the announcement it was learned that the key to the plan is what it does not include and that has become its great “surprise”: in reality there will be no naval escorts traditional boats accompanying each ship, according to Washington officials. Although the United States deploy destroyersaircraft and thousands of troops in the region, traffic will rely more on traffic management and indirect deterrence than on direct armed protection. Diplomacy, threats and an extremely fragile balance. The movement also occurs in parallel to indirect negotiations between Washington and Tehran. The messages at the moment are rather mixed, combining diplomatic optimism on the one hand… with strong warnings from both sides on the other. On one side, the United States insists that it will respond forcefully to any interference in the process. Iran, for its part, has just made it clear through its news agencies that any foreign military presence in the strait will be considered a direct threatso the United States “plan” threatens not to occur. A military deployment present but contained. There is no doubt, despite the absence of escorts direct, the environment remains heavily militarized. The United States maintains a wide presence with aircraft carriers, aircraft and unmanned platforms ready to act if the situation escalates. At the same time, naval mines have been detected and specific attacks against ships in the area. In other words, in the current scenario, transit has become an operation of calculated risk where coordination replaces direct protection. The real pulse: control, pressure and global economy. Beyond the movement of ships, what is at stake is the control of one of the most important energy arteries of the world. Iran uses the blockade as a pressure tool in the midst of negotiations, while the United States tries to unblock the situation in its own way and with one caveat: without legitimizing that control. The result is an intermediate solution that summarizes well the tension of the moment: intervene just enough so that the boats leave without causing an escalation that blows everything up into the air.

The problem with microrobots is that they don’t have a “brain.” The solution has been to use Einstein’s relativity to guide them

by

Making robots the size of a piece of human hair is already a reality, but it faces a big problem: they are too small to bring a “brain” on board. And it is logical, since on a microscopic scale there is no space to insert a microchip, batteries or navigation systems, so in a few words we can talk about “dumb robots” that only react to basic stimuli. But here the Einstein’s relativity has given a small solution. The solution. One of the functions of these small robots is precisely in be able to navigate the bloodstream to react to different stimuli. But the big question here is how they can navigate a bloodstream without colliding with each other. Something that was on the mind of a team of researchers from the University of Pennsylvania what have you seen that the key is not in making robots smarter, but in manipulating the “spacetime” through which they move. To understand this thread, you have to think about how gravity works according to the theory of general relativity. Here Einstein taught us that planets do not revolve around the sun because an invisible force pulls them, but because the mass of the Sun curves the fabric of spacetime, as with the Earth, which follows the easiest path through that curved space. To biology. Here the researchers wanted to apply this same mathematical principle to microrobotics, introducing the concept of “artificial spacetimes”. And since microscopic robots move in response to light, the scientists designed light fields projected onto a Petri dish that mimic the curvature of spacetime. In this way, the variations in light they faced acted like “artificial gravity.” In this way, the robot does not need to know where it is or where it is going. It simply turns on and moves forward, since it is the light pattern that “pushes” it to curve its path to avoid obstacles or find the exit from a maze, exactly like a ray of light curves when passing near a massive object in the cosmos. It seems like magic. In the experiment proposed by the researchers, different two-dimensional light labyrinths are projected. In this virtual scenario, they created dark areas that mathematically act as “black holes”, since when the microrobot approaches these areas, the equations that govern your response to light They are formally identical to those of the path of light falling through an extreme gravitational field. In this way, when the microrobot approaches these areas, the equations that govern its response to light are formally identical to those of the path of light falling through an extreme gravitational field. From here, using mapping, scientists managed to get these robots to ‘patrol’ specific areas, avoid obstacles and group together at an exact point. And the most interesting thing is that all this happens without a single processing chip on board the robot, since the “calculation” falls entirely on the geometry of the projected environment. A future doctor. The implications of this advance will now allow microrobots to be freed from the need to have a computer system inside them, which means they can be manufactured cheaply and even made even smaller. From here opens the door to very important medical applicationssince millions of these “reactive robots” can be injected into the human body. The objective here is to use external fields such as magnetic fields that act as a curved spacetime that allows them to move through our circulatory system to release a drug, clean arteries or perform biopsies at the cellular level.

the look that became a voice and guide

In 2019 we published a 37 minute documentary about Dulce, a girl with motor paralysis who learned to communicate using only his eyes and a system of eye-tracking by Irisbond. When she started with him, she was six years old. The learning process had just begun. The eighteen months of recording culminated with a moment that summed up the entire effort: in front of her classmates, using her communicator, Dulce announced “my mother has a baby.” Pure manifestation of desires, willingness to share. Perhaps the first time he not only named the world but shaped it. Six years later, we have spoken again with Raúl, his father. Today Dulce is thirteen years old, her brother Max is already ten, and Dante, that baby who was beginning to appear in Raquel, is already five years old. The communicator is still your voice, but what has changed is what you say with it and what you use it for. From spectator to teacher When we met her, Dulce was learning to use the device with the patience of first Celia and then Mariano, her educators. He burst virtual balloons on the screen, related pictograms with concepts, constructed basic phrases. The process was methodical and exhausting: each session required prior calibration, sustained concentration, and the diffuse promise that that, one day, would give him communicative independencesomething very remote then. Dulce introducing herself at one of her talks. Image provided. Now Dulce is on the other side. Not only does she now master the system, but she has become a trainer for other communicator users through Gema Canales Foundation. “She is as a teacher, teaching other children to use communicators because she is very good at it and has a lot of patience,” explains Raúl. “He’s taught three or four kids how to use the system already.” It is not a specific activity. According to her father, it is something she would like to continue in the future, when she is an adult. The communicator is no longer just his or her tool of expression, but also what he or she trains others in.. The transformation is complete: from student struggling to articulate simple ideas to mentor capable of transmitting technique and patience to others. Teenage conversations The most notable thing is not the technological leaps—which there have been, although moderate—but the communicative leaps. In 2018, Dulce was pronouncing single words, constructing short sentences and expressing basic desires. Six years later he has more complex conversations. “She has normal conversations of a 13-year-old teenager,” says Raúl. Image provided. The most notable change came with mobile phones. Dulce already has her own, not as the main communication device – for that she continues to use the Irisbond system connected to a tablet – but as a gateway to digital socialization typical of their age. The mobile allows you to access WhatsApp and have conversations with friends, a teenage rite of passage. Although he accesses through WhatsApp Web for fluidity and convenience, he also likes to use his cell phone with the mobility that his left hand allows. This communicative autonomy has also changed its social dynamics. Raúl remembers moments when Dulce, in new environments with strangers, starts conversations using her communicator. The other kids quickly naturalize the system: “Oh, okay, I talk and she answers me like this.” There is no discomfort, just a slight adaptation to the pace of the conversation, which is slower than natural speech but fluid to maintain complete dialogues. The voice that doesn’t want to change Technologically, the system has not evolved a lot in these six years. The most important improvements occurred in the years before the documentary, when the eye-tracking It went from crude to functional. Since then, progress has been incremental. The response speed has improved slightly, the software is somewhat more predictive, but nothing transformative. The most interesting thing is that Dulce has resisted changing the voice of the communicator. The system has been updated with more voices, even from children, not just adults, as some parents had been demanding. Image provided. When the tool added the first children’s voices, Raúl went “with all his enthusiasm” to configure it on Dulce’s tablet, but he found something unexpected: her refusal. She preferred to keep the one she has been using for years, with an adult ring. “She’s already gotten used to that being her sound. It’s like your voice changes overnight, you feel strange, you don’t recognize yourself in it.” His father speculates something obvious but easy to forget: when you’ve spent most of your life hearing yourself speak in one way, changing your voice is not an improvement, it’s losing your sound identity. The limit is still physical Dulce finished primary education with excellent grades, with the only curricular adaptation in Physical Education. Now he is in 1st year of ESO and limitations are beginning to appear, not due to cognitive ability but due to motor demand. Mathematics, which in Primary was numbers, now introduces algebra. “There it could get more complicated for her,” admits Raúl. The solution involves an assistant who transcribes what Dulce indicates with her communicator, a necessary support not because she does not understand the subject but because writing equations with her eyes is infinitely slower than by hand. It is a technical limitation, not an intellectual one, but it sets the pace of your academic progress. The impact of the documentary The 2019 report did not change Dulce’s life or that of her family. There was no media transformation or avalanche of attention. But Raúl remembers a very specific effect: when they had meetings with the Madrid Department of Education or made requests for academic support resources, someone would mention “ah, yes, you are Dulce’s family, the one from the documentary.” “I already had a face, eyes, expressiveness, a story,” he explains. “It wasn’t just a name in a dossier.” In the bureaucratic negotiation for resources and support, this minimal humanization of the file worked in their favor. It wasn’t … Read more

The arrival of the iPhone Air has changed everything. Guide to choose perfect iPhone in Apple’s new family

by

Apple has presented new iPhone, four to be exact: iPhone 17, iPhone Air, iPhone 17 Pro and Pro Max. Unlike other years, alignment has changed. The novelty is that The Plus model tells us goodbye and the new iPhone Air arrives instead. Let’s see how the iPhone family looks after launch. iPhone 17: The always base model iPhone 17 The dry iPhone. Is the successor of iPhone 16 and maintains the usual spirit: a more content size and double camera. It is the iPhone for those who do not need the triple camera or the most powerful processor. This year the iPhone 17 wins points because its screen finally adds to the 120hz, something that so far away further away from its older brothers. It is made of aluminum and, to protect the screen, it has the new Ceramic Shield 2 which is up to three times more scratch resistant. It arrives in five colors; Black and white for the most traditional and three more casual tones (lavender, green and blue). Its price starts from 959 euros For the 256GB version. iPhone Air: The new class comes wearing Tipazo iPhone Air Is The great novelty This year. After The failure of the ‘mini’ modelsApple tested the opposite: an iPhone ‘plus’ that bet on a much larger screen. The formula has not set and the iPhone Air is the new Apple attempt to sell us a fourth iPhone. As with the macbook air, The iPhone Air claim is thinness. Specifically, it measures 5.6 millimeters thick (with the exception of the camera module, where by the way Apple has managed to put practically the entire hardware) and weighs 165 grams. The iPhone Air is for those who want the most exclusive design, even at the expense of making certain sacrifices. It only has one camera and, although the figures of autonomy are not as disastrous as it was rumored (27 hours of video playback), the fact that Apple announced an external battery specially designed for this model leaves us with enough doubts. Another important factor is that It has no physical sim, So if you decide to go for the new ultradelgated iPhone, It is time to hire an ESIM. The iPhone Air arrives blank, gold, sky blue and black and its price starts from 1,219 euros For the 256GB version. This is 260 euros more expensive than the iPhone 17, but 100 euros cheaper than the iPhone 17 Pro. iPhone 17 Pro and iPhone 17 Pro Max: For the most demanding iPhone 17 Pro Max and iPhone 17 Pro If you are looking for the best experience, especially at the photographic level, you have to go for a Pro. They have a triple camera that, in addition to the wide angle, also include a teleobjective that reaches 8 increases. They also have the Apple A19 Pro processor with steam camera to avoid and carry Ceramic Shield 2 both in the front and rear. What model choose? It will depend on the size you prefer (6.3 or 6.9 inches) and also the budget. The iPhone 17 Pro Max Cuesta 1,319 euros and the iPhone 17 pro max 1,469 euros In the 256GB versions, that is 150 euros apart. A point to keep in mind is that, in addition to the screen size, the Pro Max also has more battery. iPhone 16 and 16 Plus: last year’s models still have a lot to say iPhone 16 Plus and iPhone 16 As usual, Apple keeps the iPhone 16 and iPhone 16 Plus on sale one more year. Although they are models with a year old, they are still two very interesting options For those who want to pay less, whenever he does not mind giving up some novelties. The main and most important is the soda rate. In the new models it is already 120Hz, but on the iPhone 16 it was still 60Hz. They also have the chip last year (Apple A18) and the ultra -angular chamber was still 12 megapixels. The output prices are 859 euros for the iPhone 16 and 959 euros for the iPhone 16 Plus, 100 euros reduction. iPhone 16E: The “Cheap” iPhone iPhone 16E Although he was not part of the presentation of September 9, the iPhone 16E It is still selling on the Apple website so it is part of the family. Is the successor of iPhone se And the first of its kind that bets on a Front without button where the screen is the protagonist. Of course, there is no dynamic island but the Notch Classic of previous models. It makes some concessions such as that it only carries a camera or a smaller screen. Is The iPhone for those looking for the most affordable model. However, with a price of 709 euros For the 128GB, it is not exactly cheap, especially if we compare it with the previous ones, whose price was around 530 euros.

Taking spectacular photographs of the Perseids seems impossible. NASA has a guide to demonstrate otherwise

by

The Perseids are already here and, although there are still a few days to reach their peak of activity, it is convenient to keep in mind some clues and tricks if our intention is to capture them in a photograph. Because as more than one will have proven, this is not always easy. AND Who better than NASA to point to any of these tricks. The first step: plan. If we want to get a good image of this rain of stars, the first thing is to think where and when. The Perseids or Tears of San Lorenzo can be seen for several weeks of summer, approximately between June 17 and August 24, and reach their peak of activity around August 11 and 12. Where and when it is also important when it comes to circumventing the great enemy of astrophotography: light pollution. First, it is convenient Avoid full moon And the phases in which it reflects the most light, since, although we do not perceive this light, it reduces the contrast that our eyes require to see the fleeting stars. It is also important flee from light pollution that generate the lights of cities and other settlements, so perhaps we should plan a trip to the field if we want to see these stars. Finally, we must also know where to look. Perseids owe their name that seem to radiate The constellation of Perseus. Knowing how to locating this constellation in the sky is very useful when restricting the angle to which to aim the objectives of our cameras and increase the probability of capturing some of these flashes. Second step: the team. A tripod can be helpful. Photography will require a long exposure. Maybe they are just a few seconds, but our pulse or any other involuntary movement could spoil a perfect shot. If we do not have a tripod we may resort to a “homemade” solution, such as supporting our camera on some rocks, but that will subtract maneuvering capacity. It can also be useful pertrech In order not to have the chamber trigger and thus avoid additional vibrations, but we can also dodge this requirement with the camera timer. Regarding the lens, NASA’s recommendation is in angular. Since we do not know when and where the next flash will happen, it will be best to cover a lot to increase our chances of success. Third step: Prepare. Once in position, we can start looking The constellation of Perseus. Orient our camera towards it will increase the chances of capturing the flashes of this rain of stars. The approach, best manual. The reason is that cameras self -effect systems can be lost in night darkness. Since we will not have to change the focal point, this does not imply any problem once we have taken the ideal approach. We will have, of course, to walk with an eye: sometimes focusing on infinity is not the best option, so it is a good idea to try small adjustments until you find the ideal approach. There is still a detail. We had said that capturing a rain of stars requires long exhibitions. Calculate how long can also require adjustments, but NASA also has a trick to facilitate work: Rule 500. It is about dividing 500 by the focal distance of the lens, and using the figure as time, in seconds, that our open shutter will remain. This value represents the maximum time that we can maintain the exposure before the terrestrial rotation makes the background stars begin to spread. If we have a 20 mm lens, we will have that 500/20 = 25 seconds of maximum. Experiment, enjoy. Rule 500 can be a good start, but we will still have to adjust our ISO and opening values, which will also allow us to play with shorter exhibitions. We can make small changes and verify how each one affects the quality of the image or its aesthetics. He last advice that NASA It has for those who are encouraged to photograph the persistes (or any other rain of stars) is simple: enjoy. These astronomical events offer us an opportunity to see the night sky in a different way, in advance generated by the unexpected flashes that cross the night sky on some summer nights.

If the question is “How to make a good prompt for AI”, Anthropic has just given us his guide

by

Anthropic, the creator of Claude, has published its definitive guide of Prompt Engineering. A free Bible that synthesizes years of research in practical techniques to get the most out of Claude. Why is it important. The majority of users barely scratch on the surface of what the generative AI can do, leaving below even what could benefit in their day to day, even if they are not engineering uses. The panoramic. The guide covers from the foundations to the most sophisticated. From how to be clear and direct in a request to advanced techniques such as Multishot Prompting or the chains of thought. Culminates with strategies such as the chain of Prompts complex And all enlightened with real examples of Claude. In detail. The nine central techniques of this guide function as a ladder: Clarity and direction. Say exactly what you want. Prompts Vagos produce vague results. Various examples. It shows Claude how to think with several cases of use. Thought chains. Ask Claude to think step by step before answering. XML Tags. Structure the answers with greater precision. System roles. The classic “You are a lawyer”, “You are a data analyst”, etc. To change the chatbot perspective. Prellenate of answers. Guide the tone and format starting the answer. The context. Anthropic explains that many of the problems with generative AI are solved with better Promptsnot necessarily with more powerful models. This is an attempt to democratize techniques that they only knew somewhat more advanced developers. Open the guts of what they know it works. For example. The guide includes concrete examples: Instead of ‘Create a Dashboard’, he writes ‘creates a complete analytical analytical dashboard with interactive graphics and filters’. For code Frontendadds specific modifiers: “Includes soft transitions, micro -interctions and visual effects that demonstrate advanced web development capabilities.” And for complex tasks, the guide recommends using XML labels as to structure Claude’s thought. The difference is in specificity: say exactly what you want produces much better than vague instructions. The AI ​​returns you what you give. Yes, but. There is an important nuance: this guide assumes that you already have clear success criteria and ways to evaluate results. Without that base, even the best Prompt It is a shot in the air. And now what. For developers, this is gold. For the user something else casual, It is worth dominating at least the first techniques for minimizing hallucinations and improving the results. He Prompt Engineeringthat some time ago it seemed a kind of black magic to invoke in a mystical way, it is every time a skill that can be learned, measured and better perfect.
