Almost all phones with optical zoom have the same problem. This Chinese brand believes it has solved it in a curious way

The greatest illusion trick in mobile photography is continuity between cameras. When we zoom from 1x to 5x on a telephoto smartphone, we are not moving lenses like on a camera; the mobile jumps between fixed sensors and fills the gaps with digital cropping and AI. The result is those sudden jumps in color and image in the viewfinder and a loss of quality in the “intermediate zooms” that we make when pinching the screen. Tecno, the star brand of the giant Transsion—the fifth largest manufacturer in the world hot on Xiaomi’s heels in some markets—has taken advantage of its annual event to present two technologies that attack precisely this problem: a zoom that does not “jump” and a periscope that shrinks. Optical continuous zoom. And from an increase, up to nine. The most ambitious proposal is the “Freeform Continuum Telephoto”. On paper, it promises to maintain optical sharpness throughout. It represents an important leap, although it is not the first: Sony tried it with the Xperia 1 IValthough its range was more limited. LG also showed similar concepts a few years ago, but no one had promised to cover the main angle lens to the long telephoto lens in a single module. To achieve this milestone without turning the mobile phone into a brick, the Chinese firm moves away from the traditional design of lenses that move longitudinally. Instead, they turn to physical principle of the “Alvarez Lenses”: a system that employs two lenses with free-form surfaces that move perpendicular to the optical axis. By sliding one over the other from the side, they change the optical power of the set and achieve that zoom effect. This technology is related to recent reports that Samsung was developing cameras with continuous zoom for Chinese manufacturers. A periscope that folds on itself. The second innovation presented by Tecno attacks the volume. We are obsessed with increasingly larger sensorsbut the space inside the mobile is finite. Periscopic telephoto cameras require a lot of space, but Tecno and its “Dual-Mirror Reflect Telephoto” promise to reduce the size of the module by 50% and its height by 10%. Instead of a simple prism that bends light 90 degrees, the system uses coaxial optics that bounce light multiple times inside the lens using reflective mirrors. It is what allows long focal lengths in a shorter physical distance. However, this design has a physical trace– When using a central obstruction, the bokeh is not circular, but rather takes on a donut shape. Tecno sells it as an artistic feature, the truth is that it is a consequence of mirror optics. Battle against the accused. The new thing from Tecno comes at a time when mobile photography It depends a lot on the processing what are you looking for the photo instagrammable above realism. Going for better optics instead of digital cropping and AI rescaling seems to be the right direction to achieve naturalness. However, we must maintain some caution. The challenge of this zoom is not only that it works, but that it is bright. Maintaining a decent aperture throughout that range is no easy task. If the system is too dark, the ISO will shoot up, generating noise that the software will have to remedy: back to processing. For the moment, we must wait to see if these concepts end up in a commercial mobile phone.

The curious story of how an eight -year -old girl unwittingly discovered the paintings of the Altamira cave

A few minutes by car from the precious, fresh and walkable Cantabrian town Santillana del Mar is one of the great national treasures, the Altamira cave. Closed to the public now for obvious reasons, but visited through a recreation made to the millimeter baptized as NeocuevaAltamira retains an impressive collection of Paleolithic paintings, the oldest with more than 30,000 years of history. And like many other great discoveries, we arrive at her by chance. This is its story. Modesto Cubillas. Although the discovery of the Altamira cave has always been involved in a certain controversythe Ministry of Culture of Spain He attributes it To Modesto Cubillas in 1868. The story that Cubillas was hunting when his dog fell through some rocks while chasing a dam. When attending his aid, he met the caverns, to which he did not give greater importance for 1) to be common in the region and 2) be covered with vegetation. The first visit. Cubillas told what he had seen his neighbors, but the thing was there. It was not until 1875 when Marcelino Sanz de Sautuola, naturalist, Spanish prehistoriator and great -great grandfather of Ana Botín (president of the Board of Directors of the Santander Bank), visited the cave for the first time to meet zero units of things that called him attention, beyond black lines to which he did not give importance. Input of the Neocueva that recreates the original entrance | Image: Xataka But yes … Years later, Marcelino attended the Universal Exhibition of Paris in 1878 And there he could see prehistoric objects. How were, how to identify them. Armed with new knowledge, he decided to return to the cave with the little girl María San de Sautuola y Galantehis daughter of only eight years. That was in 1879. The innocent curiosity. While the father was looking for remains at the entrance of the cave, little Maria, motivated by the innate curiosity of a girl of her age, decided to continue forward and enter the gallery. Upon arriving at the bottom, Maria shouted “Look Dad, oxen” while pointing to the roof. They were not oxen, but bison, but the error was normal: the oxen were the shot animals used in the area. Marcelino identified the species represented as the bison, which was then considered extinct in Europe, but did not find bones of the animal in the cave. Given the unusual of the cave, whose realistic paintings extended throughout the roof, thus being one of the most important and large discoveries of the moment, all kinds of debates were generated. From the denialism of discovery to accusations that it had been Marcelino himself who had painted the figures. The years, however, would be right, although this could write rivers and ink rivers. They were not oxen, they were bison | Image: Xataka And he got. The news of the discovery of the paintings soon arrived at the nearby corners. Hundreds and hundreds of people approached the cave carrying, in an entire exercise of irresponsibility as a result of ignorance, candles, candiles, compasses and strings. The visitors took the remains to their home, chopped the ground to find more and the cave began to deteriorate. Thus, Marcelino Sanz de Sautuloa decided to place a wooden door on the hole that made the entrance. Puerta that paid from his own pocket and after obtaining the authorization of the village of Vispieres, headlines of the cave. In return, he invited them to a snack that took place, curiously, inside Altamira. In the lower image the signed document can be seen and the promise of making a snack. Later, in 1880, the wooden door was changed to an iron fence and a guard was appointed. Authorization signed by the neighbors to put a wooden door at the entrance of the cave | Image: Xataka Entrance is not the original. An important note: the hole that was covered with a fence was not the original entrance. The great mouth of the cave where the inhabitants of Altamira made life collapsed 13,000 years ago. That entry remained covered until its discovery in 1869. Thanks to the stability of the inner atmosphere, the paintings have been able to preserve well for millennia. The current entrance was built in 1927 and the closest to the original mouth is the entrance to the Neocueva. THE VISITS PROBLEM. Returning to La Cueva, in 1910 the City Council of Santillana del Mar created a conservation and defense board of the cave that, back in 1917, allowed the visit with a guide. In 1924 he was declared a National Monument and the rest can be imagined. The number of people who accessed the cave increased more and more, being the 60s and 70s the most dangerous. Only in 1973 more than 174,000 people accessed inside. Such was the influx of people who, after a study and A debate that reached the Congress of DeputiesIn 1977 he closed. Panoramic roof of the Altamira cave | Image: Xataka Closed. Altamira closed its doors until 1982, when it was reopened with a limited capacity of 8,500 people a year. The interest of the people valued the idea of creating a visitable replica, something that happened in 2001 with the Neocueva located in the newly opened National Museum and Research Center of Altamira. In 2002, the cave closed the public again Waiting for impact studies. It would be reopened in February 2014 and until August of that same year, admitting five people per day for 37 minutes to study the impact of possible visits. The sign.

The Rimac Nevera R has two curious records. It is the fastest electric in the world and, at the same time, nobody wants to buy it

He RIMAC Nevera r He has monopolized the attention of the whole world for his impressive speed and power figures. However, this electrical hyperdeportive, despite break speed recordshe has not managed to conquer the heart (or the wallet) of the wealthiest buyers. That produces the strange paradox that, while motor world fans celebrate the technological advances applied to one of the most brutal electrical hyperdeporters that have existed, the reality of their sales dazzles their track achievements. A world speed record that is not enough. The Rimac Nevera R has beaten the World Speed record For production electric cars, reaching an official brand of 431.45 km/h. However, the fridge R could not maintain Your domain in Nürburgringwhere it was overcome by the Xiaomi Su7 Ultrawhich became the Electric faster in rolling for the green hell of Nürburgring, despite being a superberlina and not a hyperdeportivo like the fridge R. Mate Rimac, founder of the Bugatti brand and CEO, acknowledged in a company statement that “Beating records is in our DNA, and we will not stop here.” However, according to The published by Bloombergdespite these achievements on the track the fridge R has not achieved the expected commercial impact. Why don’t Millionaires want the fridge r? One of the hypotheses that have considered Rimac is that the low demand can be related to the preference of high purchasing power for combustion hyperdeporters. According to collected CoachMate Rimac believed that “the market for electrical hyperdeporters is very limited. Most buyers in this segment still want the drama and emotion of an internal combustion engine.” This reluctance a embrace electrification In the hyper -sports segment it limits the potential market of the fridge R, however impressive their technical figures are. The Croatian brand acknowledges that “it is unlikely that we will manufacture another electric hypercoche in the short term”, reflecting the difficulty of convincing millionaires to change gasoline for electricity, even if it is 431.6 km/h. Only 40 units and record power. The RIMAC Nevera R is a limited edition based on the original fridge, but with an increased power in 200 hp with respect to the Original Neverareaching a total of 2,017 hp. As usual with the hypercoches, of the original fridge only 150 units will be manufactured, but in the case of the fridge R, its roll will be even lower, since it is a limited edition to 40 units, which underlines its exclusivity in the market of electrical hyperdeporters. The price of each unit is around 2.3 million euros more taxes, placing it at the top of the most expensive electric cars in the world. This combination of power and exclusivity has not been enough to convince the richest buyers, who seem to prefer other options. Porsche is worried about Rimac’s sales. In Porsche they are not satisfied with the sales figures of the refrigerator and motives are not missing. According to him annual report From Porsche, the German brand has 20% of Rimac’s shares, which makes it a part interested in the financial success of the Croatian company. “The profitability of our investments in Rimac depends on the commercial success of its models,” says Porsche report. The low sales level has generated a 46% collapse in the benefits up to 182 million euros. According to Autocar, in May 2024, the brand had only delivered 50 units of the refrigerator of the 150 that was going to manufacture. Before such a panorama, the additional 200 hp offered by the fridge R is not expected to be sufficient incentive for the millionaires to queue in the brand’s dealerships to take one. Maybe still Not the moment of electrical supercar. In Xataka | Bugatti has found a new reef: his clients are spent on average 500,000 euros on extras to customize his car Image | Rimac

In South Korea there is a curious phenomenon that keeps economists and fans of the K-Pop in suspense: the return of BTS

For a time BTS’s careerone of the most popular K-Pop bands on the planet (if not the most popular), seemed unstoppable. Their sales added millionslike his Fans legions Inside and outside South Korea or its fame in the music industry, which soon extended to the Anglopartla market. The Septeto broke barriers, crowned in the Billboard 200 And even posed with Joe Biden In the White House. In 2022 however things changed. At its peak, the Boy Band advertisement A temporary pause forced by something that had little to do with music: the mili. Now its seven members have fulfilled the obligations with Seoul and You talk already next resentment With a background question: what will you mean for the K-Pop, a cultural industry Milmillonaria In full transformation? When BTS hung the rifle. In South Korea the law is relentless: all men between 18 and 28 must Comply with mandatory military service (or social volunteering) for a period ranging between 18 and 21 months. The rule provides some exemptions for athletes, dancers or young people who have achieved large awards in their disciplines and suppose a pride for the country. The same does not happen with K-pop singers. At most they can, thanks to a reform approved in 2020, delay recruitment up to 30 years. Hence In 2022 BTS members did something strange in a formation uploaded to the crest of the wave and with a growing fame both inside and outside Korea: they announced a break to do the mili. Its seven components do not have the same age or enlisted at the same time, hence the band’s reunion It was announced already by then by 2025. And the date came. The oldest component, Jin, was enlisted in December 2022 and ended his service in June 2024which has allowed him to return to the stage and resume his solo career. In recent weeks, RM, V, Jimin and Jung Kook have also graduated. The last to fulfill its obligations with the South Korean state, Suga, did it Just a few days ago. In practice, Remember Nikkeithat means that (if there are no surprises) in July all members of the Boy Band They will be able to resume their joint career. And, as expected, that has unleashed the expectation of the international press and its fans. The agency that represents the band has confirmed to The New York Times That he still cannot relieve any return plan, but that has not prevented BTS fans from being celebrated and some leaks jump. A few days ago Variety It echoed of an exclusive of The Korea Herald That states that the group will return to the stage in more or less nine months, towards March next year. Nikkei does not specify so much, but reveals That the band’s environment rules out that a stage is once again on the stage. Much more than pop music. That BTS’s return plans (despite being diffuse still) have monopolized holders in the means of reach of The BBC, CNN either Tnytreveals that Boy Band South Korean is much more than a popular group. BTS is relevant for several reasons. And not all strictly musical. Beyond its success in the West or to break molds by crowning the Billboard 200, BTS is a key exponent of Hallyu, The “Korean wave” that has expanded the culture, music and cinema of the country far beyond its borders. In 2024 Asia Fund Managers assuredciting a survey of the South Korean government itself, which the Hallyu wave added around 225 million fans throughout the world, far from the 9.26 million that its first survey had shown, made in 2012. According to its calculations, in 2023 there were more than 1,700 Hallyu fans clubs in 119 countries and much of them (68%) focused on the K-Pop. It’s culture … and it’s money. Asia Fund Managers remember Also that the influence of the K-Pop is not limited to the music industry or the concert circuit. That there are more pending people of South Korean groups translates into greater interest in the country’s culture, their language, kitchen, tourism or fashion, which has a measurable impact on Wones. Wion ensures that the global value of exports of products and services related to the K-POP exceeded 5,000 million dollars in 2018, a stratospheric figure compared to 40 million only two decades ago. The figures should be handled cautiously, but give an idea of ​​the mayor of the K-Pop as a cultural industry. There is Who esteem which in 2018 contributed 1.7% of South Korea’s GDP. “K-pop has become an important cultural force, influencing fashion, beauty and language trends,” Reflect ROMADHONI FAILUATE IN MEDUM. “This has contributed to promoting South Korean culture and tourism, generating an increase in income in these sectors.” And what does BTS suppose? In 2022 Korea Science published A report which reflects that in full international expansion the “BTS effect” came to boost exports of consumer goods of South Korea worth $ 1.1 billion. In 2021, during An interview In the NPR, Vanek Smith went even further and estimated that the Boy Band It contributes hundreds and hundreds of millions of dollars every year to the South Korean economy. Its effect reminds in a way that of Taylor Swift, whose activity reverses in thousands of millions of dollars for the United States, according to the Federal Reserve. The K-Pop in crisis? Yeah Filtration of The Korea Herald It is correct and BTS returns to the stage in March 2026, the big question is … will it meet the same K-Pop in 2022, when the group announced its temporal break? During this time already measured, some members have continued with solo careers and during these last years their agency has strategically launching issues and videos to keep interest in the Boy Band. The K-POP scene also has other outstanding representatives, such as Blackpink, Seventeen either Newjaans. However, during the last years There has been multiple voices that have identified symptoms of Crisis in the K-Pop. … Read more

This is how the curious creator of LG wallpapers works

We have moved to Frankfurt to see and touch firsthand THE NEW LG TREES FOR 2025 And by the way, try the latest version of Webos. We have found a twist more to a consolidated Operating system seasoned with great artificial intelligence. That artificial intelligence reaches televisions makes more sense than it seems and, leaving aside some profits that have been essential and other more or less useful, if there is one with a point of experimentation, creativity and fun that has caught us, that is the to generate images with AI, called Image Ai Solution (By Google). I have done my TV’s background with ia To get the best results you have to approach the command to the mouth Creating images with artificial intelligence is not something new, but it is fashionable: you have Midjourney, Dall- e3 And in general, A long list of free applications. Do it on devices that are not the computer, mobile or tablet is the order of the day, but Generate your images from TV and with voice is another story. As of tweet With your LG fridge of that teenager who went viral, but really. Why generate images with TV? LG’s response could simply be breastfeeding: ‘Because I can’, but the reality is that he has his one, for example to have a wallpaper of our family in the style of ‘The Lord of the Rings’ or simply so that the next time someone uses TV, a birthday greeting appears just on that day anniversary of his birth. Let it know that it is possible to do it by text, but The most natural and agile on a TV is to pull the voice and make use of suggestions to polish the prompt until we get what we want. For this, the new Magic Remote AI remote control has a button to invoke its AI that we must keep pressed while we talk to capture the entire phrase. This function of generation of images with AI is in beta and I tried it in English (it was ESO or Korean, it is not available in Spanish) in a living room with enough noise, which meant some problems when the remote control captured the words well. In this sense, yours is approach the command to the mouth and that the room is silent. In my evidence I started from simple concepts such as drawing a dog, a cat (we said ‘cat’ but understood ‘God’) and even something much more complex and detailed as samurais with dragon plates armor in the middle of some cherry trees. Overcome the barrier of understanding the order, The results were surprisingly good. The model used to generate images is Exaone-3.5 (whose repository is available In Github) and includes 100 free creditswhat I would give for a hundred generations. If later you would like to generate more images, the specialized engineers told us that the idea is to adopt a billing system. With these generated images, it is possible to download them to save, share them and of course, use them as a unique and exclusive wallpaper made by ourselves, an addition that makes personalization rise level and also, another way of Generate income through TV softwaresuch as integrated advertising or ads LG Channels.
