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.

How China can transform from passive to active amid US chip curbs
On Monday, executives from the three major chip giants in the US - Intel, Qualcomm, and Nvidia - met with US officials, including Antony Blinken, to voice their opposition to the Biden administration's plan of imposing further restrictions on chip sales to Chinese companies and investments in China. The Semiconductor Industry Association also released a similar statement, opposing the exclusion of US semiconductor companies from the Chinese market. First of all, we mustn't believe that the appeals of these companies and industry associations will collectively change the determination of US political elites to stifle China's progress. These US elites are very fearful of China's rapid development, and they see "chip chokehold" as a new discovery and a successful tactic formed under US leadership and with the cooperation of allies. Currently, the chip industry is the most complex technology in human history, with only a few companies being at the forefront. They are mainly from the Netherlands, Taiwan island, South Korea, and Japan, most of which are in the Western Pacific. These countries and regions are heavily influenced by the US. Although these companies have their own expertise, they still use some American technologies in their products. Therefore, Washington quickly persuaded them to form an alliance to collectively prevent the Chinese mainland from obtaining chips and manufacturing technology. Washington is proud of this and wants to continuously tighten the noose on China. The New York Times directly titled an article "'An Act of War': Inside America's Silicon Blockade Against China, " in which an American AI expert, Gregory Allen, publicly claimed that this is an act of war against China. He further stated that there are two dates that will echo in history from 2022: The first is February 24, when the Russia-Ukraine conflict broke out, and the second is October 7, when the US imposed a sweeping set of export controls on selling microchips to China. China must abandon its illusions and launch a challenging and effective counterattack. We already have the capability to produce 28nm chips, and we can use "small chip" technology to assemble small semiconductors into a more powerful "brain," exploring 14nm or even 7nm. Additionally, China is the world's largest commercial market for commodity semiconductors. Last year, semiconductor procurement in China amounted to $180 billion, surpassing one-third of the global total. In the past, China had been faced with the choice between independent innovation and external purchases. Due to the high returns from external purchases, it is easy for it to become the overwhelming choice over independent research and development. However, now the US is gradually blocking the option of external purchases, and China has no strategic choice but to independently innovate, which in turn puts tremendous pressure on American companies. Scientists generally expect that, although China may take some detours, such as recently apprehending several company leaders who fraudulently obtained subsidies from national semiconductor policies, China has the ability to gradually overcome the chip difficulties. And we will form our own breakthroughs and industrial chain, which is expected to put quite a lot of pressure on US companies. If domestic firms acquire half of China's $180 billion per year in chip acquisitions, this would provide a significant boost for the industry as a whole and help it advance steadily. The New York Times refers to the battle on chips as a bet by Washington. "If the controls are successful, they could handicap China for a generation; if they fail, they may backfire spectacularly, hastening the very future the United States is trying desperately to avoid," it argued. Whether it is a war or a game, when the future is uncertain, what US companies hope for most of all is that they can sell simplified versions of high-end chips to China, so that the option of external purchases by China continues to exist and remains attractive. This can not only maintain the interests of the US companies, enabling them to obtain sufficient funds to develop more advanced technologies, but also disrupt China's plans for independent innovation. This idea is entirely based on their own commercial interests and also has a certain political and national strategic appeal. Hence, there is no shortage of supporters within the US government. US Secretary of the Treasury Janet Yellen seems to be one of them, as she has repeatedly stated that the US' restrictions on China will not "fundamentally" hurt China, but will only be "narrowly targeted." The US will balance its strict suppression on China from the perspective of maintaining its technological hegemony, while also leaving some room for China, in order to undermine China's determination to counterattack in terms of independent innovation. China needs to use this mentality of the US to its advantage. On the one hand, China should continue to purchase US chips to maintain its economic fundamentals, and on the other hand, it should firmly support the development of domestic semiconductor companies from both financial and market perspectives. If China were to continue relying on exploiting the gaps in US chip policies in the long term, akin to a dependency on opium, it would only serve to weaken China further as it becomes increasingly addicted. China's market is extremely vast, and its innovation capabilities are generally improving and expanding. Although the chip industry is highly advanced, if there is one country that can win this counterattack, it is China. As long as we resolutely continue on the path of independent innovation, this road will definitely become wider. Various breakthroughs and turning points that are unimaginable today may soon occur.
"Pictures on the wall were falling," New Yorkers rattled by earthquake
An earthquake jolted New York City on Friday morning, followed by more than 10 aftershocks which shook New Jersey, sending tremors as far as Philadelphia to Boston and jolting buildings in Manhattan and throughout its five boroughs. The preliminary quake, measuring 4.8 magnitude, centered around Lebanon, New Jersey, approximately 60 kilometers from New York City, with a depth of about 5 kilometers. Following the earthquake, New York City mayor Eric Adams stated at a press conference that no injuries had been reported, but they would continue to monitor and inspect critical infrastructure. The densely populated New York City was caught off guard by the unusual event. Broadcaster CBS reported that New York had not experienced an earthquake of this magnitude since 1884. Residents in Brooklyn expressed their shock when experiencing tremors which shook the city. "At first, I thought it was just construction next door, but then I noticed the pictures on the wall had fallen," Jennifer Wu, a resident in New York, told the Global Times on Saturday. Video footage circulating online showed the Statue of Liberty and the New York City skyline trembling as the earthquake struck. An angle from directly above Lady Liberty caught Ellis Island shaking during the incident. "It is fine," New York's famous Empire State Building posted on social platform X after the earthquake. The United Nations headquarters located in New York was hosting a Security Council meeting on the Israeli-Palestinian issue, and diplomats present in the meeting felt the tremors, local media reported. According to the Weather Channel, residents in Baltimore, Philadelphia, New Jersey, Connecticut, Boston and other areas of the Northeast seaboard also reported shaking. Tremors lasting for several seconds were felt over 200 miles away near the Massachusetts-New Hampshire border. The New York mayor told the press that New Yorkers should go about their normal day, while the governor Kathy Hochul emphasized the seriousness of the situation. She initiated assessments for damage across the state and had discussions with New Jersey Governor Phil Murphy. The quake caused flight delays throughout the New York area, with temporary control measures put in place across New York's John F. Kennedy International Airport, Newark Liberty International Airport in Newark, New Jersey, and Baltimore-Washington's Thurgood Marshall International Airport, checking for damage to runways. Operations resumed around Friday noon, ABC reported.
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.
South Korean government decides not to punish interns who resign
South Korea's Minister of Health and Welfare Cho Kyu-hong said at a press conference on the 8th local time that after comprehensively considering the suggestions of frontline interns and the situation on the front line of medical care, the government decided that from that day on, all interns and residents who resigned would not be given administrative sanctions such as revoking their medical licenses. Cho Kyu-hong also said that for interns and residents who have returned to work and those who have resigned and are preparing to re-register for internship courses in September, the government will make special cases to try to minimize the internship gap and not affect the relevant doctors from obtaining specialist medical licenses. Cho Kyu-hong said that the government believes that in order to minimize the diagnosis and treatment gaps for critically ill and emergency patients and ensure the smooth training process of interns and residents, it is in the public interest, so it has made a decision not to punish interns and residents who resigned. It is hoped that major hospitals will complete the resignation processing of doctors who have not returned to work before July 15 and determine the scale of vacancies. Previously, large general hospitals in South Korea, such as Seoul National University Hospital, Yonsei University Severance Hospital, and Seoul Asan Medical Center, suspended or limited their medical services in an effort to cancel all penalties against interns and residents.
US foreign policy is advanced smartphone with weak battery
A couple of days ago, a Quad summit meeting in Sydney scheduled for May 24 was abruptly canceled. The US president had to pull out of his long-anticipated trip to Australia and Papua New Guinea. Instead, the heads of the four Quad member states got together on the margins of the G7 Summit in Hiroshima on May 20. The main reason for the change of plans was the continuous struggle between the White House and Republicans on the Hill over the national debt ceiling. If no compromise is reached, the US federal government might fail to meet its financial commitments already in June; such a technical default would have multiple negative repercussions for the US, as well as for the global economy and finance at large. Let us hope that a compromise between the two branches of US power will be found and that the ceiling of the national debt will be raised once again. However, this rather awkward last-minute cancellation of the Quad summit reflects a fundamental US problem - a growing imbalance between the US geopolitical ambitions and the fragility of the national financial foundation to serve these ambitions. The Biden administration appears to be fully committed to bringing humankind back to the unipolar world that existed right after the end of the Cold War some 30 years ago, but the White House no longer has enough resources at its disposal to sustain such an undertaking. As they say in America: You cannot not have champagne on a beer budget. The growing gap between the ends that the US seeks in international relations and the means that it has available is particularly striking in the case of the so-called dual containment policy that Washington now pursues toward Russia and China. Even half a century ago, when the US was much stronger in relative terms than it is today, the Nixon administration realized that containing both Moscow and Beijing simultaneously was not a good idea: "Dual containment" would imply prohibitively high economic costs for the US and would result in too many unpredictable political risks. The Nixon administration decided to focus on containing the Soviet Union as the most important US strategic adversary of the time. This is why Henry Kissinger flew to Beijing in July 1971 to arrange the first US-China summit in February 1972 leading to a subsequent rapid rapprochement between the two nations. In the early days of the Biden administration, it seemed that the White House was once again trying to avoid the unattractive "dual containment" option. The White House rushed to extend the New START in January 2021 and held an early US-Russia summit meeting five months later in Geneva. At that point many analysts predicted that Biden would play Henry Kissinger in reverse - that is he would try to peace with the relatively weaker opponent (Moscow) in order to focus on containing the stronger one (Beijing). However, after the beginning of the Russia-Ukraine conflict, it became clear that no accommodation with the Kremlin was on Biden's mind any longer. Still, having decided to take a hard-line stance toward Moscow and to lead a broad Western coalition in providing military and economic assistance to Kiev, Washington has not opted for a more accommodative or at least a more flexible policy toward Beijing. On the contrary, over last year one could observe a continuous hardening of the US' China policy - including granting more political and military support to the Taiwan island, encouraging US allies and partners in Asia to increase their defense spending, engaging in more navel activities in the Pacific and imposing more technology sanctions on China. In the meantime, economic and social problems within the US are mounting. The national debt ceiling is only the tip of an iceberg - the future of the American economy is now clouded by high US Federal Reserve interest rates that slow down growth, feed unemployment and might well lead to a recession. Moreover, the US society remains split along the same lines it was during the presidency of Donald Trump. The Biden administration has clearly failed to reunite America: Many of the social, political, regional, ethnic and even generational divisions have got only deeper since January 2021. It is hard to imagine how a nation divided so deeply and along so many lines could demonstrate continuity and strategic vision in its foreign policy, or to allocate financial resources needed to sustain a visionary and consistent global leadership. Of course, the "dual containment" policy is not the only illustration of the gap between the US ambitions and its resources. The same gap inevitably pops up at every major forum that the US conducts with select groups of countries from the Global South - Africa, Southeast Asia, Latin America or the Middle East. The Biden administration has no shortage of arguments warning these countries about potential perils of cooperating with Moscow or Beijing, but it does not offer too many plausible alternatives that would showcase the US generosity, its strategic vision, and its true commitment to the burning needs of the US interlocutors. To cut it short, Uncle Sam brings lots of sticks to such meetings, but not enough carrots to win the audience. In sum, US foreign policy under President Joe Biden reminds people of a very advanced and highly sophisticated smartphone that has a rather weak battery, which is not really energy efficient. The proud owner of the gadget has to look perennially for a power socket in order not to have the phone running out of power at any inappropriate moment. Maybe the time has come for the smartphone owner to look for another model that would have fewer fancy apps, but a stronger and a more efficient battery, which will make the appliance more convenient and reliable.
