Enhance Your Photos With NASA's Sharpening Technique

Incredible space photos like those from NASA don't look as stunning straight out of the telescope. They need significant processing, and a crucial part of that is sharpening.

Coming to you from Unmesh Dinda with PiXimperfect, this fascinating video explores the APF-R plugin, developed by award-winning astrophotographer Christoph Kaltseis. APF-R stands for Absolute Point of Focus, and it's designed to enhance photo details without creating halos or artifacts. This technology has been used by space agencies with telescopes like the James Webb, and now, you can use it in Photoshop. The plugin allows for non-destructive editing, meaning you can adjust the radius and detail level without permanently altering your image. This feature is crucial for astrophotography, where preserving original details is vital.

The video shows how APF-R compares to Photoshop's built-in sharpening tools. The plugin offers multiple rendering methods, each suited for different types of images. For instance, the "Center Weighted" method provides a balanced sharpening effect without making the image look overprocessed. Dinda explains how to fine-tune these settings to achieve the best results, making it clear why this plugin is a game-changer for photographers looking to enhance their images with precision.

One notable feature of APF-R is its ability to work with different image types. The video demonstrates how the plugin enhances not just space photos but also landscapes and portraits. For portraits, APF-R can bring out skin textures and eye details without creating the unwanted halos that traditional sharpening methods often produce. Dinda also shows how to combine APF-R with other Photoshop tools, like Smart Sharpen, for even better results. This versatility makes APF-R a valuable addition to any photographer's toolkit.

The plugin's cost is $50, which Dinda considers a bargain given its advanced capabilities. There's also a Creative Bundle subscription that includes APF-R and 20 other tools, offering great value for those looking to expand their editing options. Dinda provides discount codes in the video description, making this sophisticated tool more accessible. Check out the video above for the full rundown from Dinda.

US' ban on high-tech investment cannot stifle China's high-tech development
US President Joe Biden signed an executive order on Wednesday restricting investments in China, intended to further stymie China's advances in three cutting-edge technology areas: semiconductors and microelectronics, quantum information technologies and certain artificial intelligence systems. The "decoupling" of high tech from China began under Donald Trump, and the Biden administration has continued that ambition. However, the new order doesn't target US investments already invested in China, but the new ones. The Biden administration has repeatedly claimed that the US restrictions will be narrowly targeted and will not "have a fundamental impact on affecting the investment climate for China." Biden's new executive order is still subject to consultation with the US business community and the public and is not expected to take effect until next year. The order has been brewed for a long time and has generated a lot of publicity. But almost no one believes that this executive order will deal a new practical blow to Chinese high technology, because almost everyone knows that China needs American technology more than American money. The order has gained much attention because it is seen as part of a broader trend of the US drifting away from China. The promulgation and brewing process of the executive order reflects the strong desire of American political elites to suppress China's high-tech development, as well as a fierce game between those supporting the executive order and the concerns of the technology and economic sectors about a potential backfire on the US. It is a kind of compromise. Washington obviously hopes that major allies will follow Biden's executive order. The UK's Sunak government has made cautious statements, stating that it is consulting business and the financial sector before deciding whether to follow suit. In fact, China also has the ability to influence the extent to which Biden's executive order is implemented, as well as the extent to which the US will go in terms of "decoupling" from China. We are definitely not just passive recipients of US policies. American political elites are eager to "decouple" from China as quickly and deeply as possible, but they fear two things: First, this will immediately damage the performance of relevant high-tech companies in the US, undermine their influence and further innovation. The current Biden administration, in particular, does not want to incur strong resentment from Silicon Valley and Wall Street toward the escalating "decoupling," which will ultimately lead to the loss of support for the Democratic Party. Second, they are afraid of pushing China toward more resolute independent innovation to achieve breakthroughs in key technologies such as chips. If the US "decoupling" policy gives birth to major technological achievements in China, it means that Washington will completely lose the gamble: They originally wants to stifle China's high-tech development, but ends up strangling their own companies. What China needs to do next is to fully unleash our innovation vitality, continuously reduce our dependence on high-tech products from the US, and prove that as long as we are determined to achieve independent innovation, we have the ability to accomplish things. We need to prove that being pressured by the US will only make us stronger. As long as there are several solid proofs of this trend, the US policy community will fall into unprecedented chaos, and their panic will be much more severe than when they saw the rapid expansion of the Chinese economy before Trump started the trade war. Regardless of the future of China-US relations, the current battle will be the key battle that determines the future competition between China and the US. China can only win and cannot afford to lose. High-tech products such as chips are not isolated. The innovation power of China's entire manufacturing industry and the creative vitality of the whole society are the foundation for shaping these key achievements. When pressured by the US, our society needs to generate confidence and resilience from all directions, and we need to accelerate and seize every opportunity, rather than shrink and simply defend. Otherwise, the US will gain the upper hand in momentum, and we will truly be in a passive and defensive position. We must see that the US is on the offensive, but its offensive is becoming weaker and weaker, and it is always hesitant with each step. What is presented to China are difficulties and risks, but also the dawn of victory.
OpenAI's internal AI details stolen in 2023 breach, NYT reports
July 4 (Reuters) - A hacker gained access to the internal messaging systems at OpenAI last year and stole details about the design of the company's artificial intelligence technologies, the New York Times reported, opens new tab on Thursday. The hacker lifted details from discussions in an online forum where employees talked about OpenAI's latest technologies, the report said, citing two people familiar with the incident. However, they did not get into the systems where OpenAI, the firm behind chatbot sensation ChatGPT, houses and builds its AI, the report added. OpenAI executives informed both employees at an all-hands meeting in April last year and the company's board about the breach, according to the report, but executives decided not to share the news publicly as no information about customers or partners had been stolen. OpenAI executives did not consider the incident a national security threat, believing the hacker was a private individual with no known ties to a foreign government, the report said. The San Francisco-based company did not inform the federal law enforcement agencies about the breach, it added. OpenAI in May said it had disrupted five covert influence operations that sought to use its AI models for "deceptive activity" across the internet, the latest to stir safety concerns about the potential misuse of the technology. The Biden administration was poised to open up a new front in its effort to safeguard the U.S. AI technology from China and Russia with preliminary plans to place guardrails around the most advanced AI Models including ChatGPT, Reuters earlier reported, citing sources.
Could a $600 billion funding gap crush the AI industry?
On July 5, Microsoft co-founder Bill Gates appeared on the Next Big Idea podcast to discuss his vision for Superhuman artificial intelligence and technological progress. At the same time, it said that the enthusiasm of the AI market is far more than the Internet bubble. Gates believes that the current threshold for entry in the AI field is very low, and the entire market is in a fever period, AI startups can easily get hundreds of millions of dollars in financing, and even have raised $6 billion (about 43.734 billion yuan) in cash for a company. "Never before has so much capital poured into a new area, and the entire AI market has fallen into a 'frenzy' in terms of market capitalization and valuation, which dwarfs the frenzy of the Internet and automotive periods in history." Gates said. At this stage, the rapid development of the artificial intelligence industry is a veritable gold industry, and Nvidia's market value is therefore soaring, and the total market value reached 3.34 trillion US dollars on June 18 local time, surpassing Microsoft and Apple in one fell fell, becoming the world's most valuable listed enterprise. But in fact, doubts about the field of artificial intelligence have also risen one after another and have never stopped.
Hedge fund Elliott challenges court verdict it lost against LME on nickel
LONDON, July 9 (Reuters) - U.S.-based hedge fund Elliott Associates on Tuesday urged a London court to overturn a verdict supporting the London Metal Exchange's (LME) cancellation of nickel trades partly because the exchange failed to disclose documents. The LME annulled $12 billion in nickel trades in March 2022 when prices shot to records above $100,000 a metric ton in a few hours of chaotic trade. Elliott and market maker Jane Street Global Trading brought a case demanding a combined $472 million in compensation, alleging at a trial in June last year that the 146-year-old exchange had acted unlawfully. London's High Court ruled last November that the LME had the right to cancel the trades because of exceptional circumstances, and was not obligated to consult market players prior to its decision. Lawyers for Elliott told London's Court of Appeal that the LME belatedly released documents in May detailing its "Kill Switch" and "Trade Halt" internal procedures. It also newly disclosed an internal report that Elliott said detailed potential conflicts of interest at the exchange. "It was troubling that one gets disclosure out of the blue in the Court of Appeal for the first time," Elliott lawyer Monica Carss-Frisk told the court. Jane Street Global did not appeal the ruling. "If we had had them (documents) in the proceedings before the divisional court, we may well have sought permission to cross examine." LME lawyers said the new documents were not relevant. "The disclosed documents do not affect the reasoning of the divisional court or the merits of the arguments on appeal," the exchange said in documents prepared for the appeal hearing. "Elliott's appeal is largely a repetition of the arguments which were advanced, and rightly rejected." The LME said it had both the power and a duty to unwind the trades because a record $20 billion in margin calls could have led to at least seven clearing members defaulting, systemic risk and a potential "death spiral". Elliott said the ruling diluted protection provided by the Human Rights Act and also wrongly concluded the LME had the power to cancel the trades.
Diphtheria outbreak in Vietnam kills one person
On the afternoon of July 8, local time, the Vietnamese Ministry of Health issued a notice stating that an 18-year-old girl in the country died of diphtheria. The Ministry of Health asked Nghe An Province and Bac Giang Province to take urgent action to control the epidemic. Diphtheria is an acute respiratory infectious disease caused by Corynebacterium diphtheriae, which is mainly transmitted through droplets and can also be indirectly transmitted by contact with objects containing Corynebacterium diphtheriae. Severe cases may show symptoms of poisoning throughout the body, complicated by myocarditis and peripheral nerve paralysis.
