Researchers Use Nanotechnology to Shrink Optics for Devices

University of Ottawa researchers have done some groundbreaking work on lenses, using nanotechnology to develop so-called metalenses that dramatically shrink down optics. But lenses still rely on space to produce images and the researchers have presented the concept of an optical “spaceplate” that propagates light for a distance much longer than the plate thickness, enabling future imaging systems to shrink even further. A spaceplate can be used to miniaturize all kinds of devices that manipulate light. “It’s a possibly revolutionary development in the field of optical science,” suggests photography and camera news site PetaPixel.

Pinterest: Neural Networks Boost Ad Sales and User Growth

Pinterest allows users to “pin” photos and videos onto boards, helping them to “discover ideas through images,” especially those pinned by people or companies that they follow. It uses neural networks, which make millions of calculations quickly, to surface and suggest the images that people will like. According to Pinterest senior vice president of engineering Jeremy King, this tool is responsible for “nearly 100 percent” of the company’s growth. In Q1, Pinterest’s AI-powered formula drew in almost 480 million people. Continue reading Pinterest: Neural Networks Boost Ad Sales and User Growth

USC Researchers Find Bias in Deepfake Detectors’ Datasets

The advent of deepfakes, which replace a person in a video or photo by likeness of someone else, has sparked concern that the ease of using machine learning tools to create them are readily available to criminals and provocateurs. In response, Amazon, Facebook and Microsoft sponsored the Deepfake Detection Challenge, which resulted in several potential tools. But now, researchers at the University of Southern California found that the datasets used to train some of these detection systems demonstrate racial and gender bias. Continue reading USC Researchers Find Bias in Deepfake Detectors’ Datasets

Pinterest to Foster Influencer Content with New Creator Fund

Although image-sharing service Pinterest has been less reliant upon influencer culture than Instagram and other social media platforms, that began to change when it introduced Story Pins and creator profiles. These features were intended to make it easier for high-profile users to build a following and showcase their projects. Now, Pinterest is unveiling a $500,000 Creator Fund to pay a small group of influencers to create content for the platform. With this initiative, it joins TikTok and Snapchat in paying creators. Continue reading Pinterest to Foster Influencer Content with New Creator Fund

Pew Research Study Finds Social Media Use Remains Stable

A new report from the Pew Research Center found that 72 percent of U.S. adults use social media, a number that has been stable over the past five years. The survey drilled down into use of a variety of individual sites and apps, finding that YouTube and Facebook still are dominant, with 81 percent and 69 percent respectively of those surveyed reporting using those sites. YouTube and Reddit were the only platforms that saw “statistically significant” growth since 2019. Forty percent said they ever use Instagram. Continue reading Pew Research Study Finds Social Media Use Remains Stable

CES: Airpeak Drone Designed for Capturing Photos and Video

First announced in November of last year, Sony unveiled a drone at CES 2021 that the company says is the smallest of its kind capable of accommodating a Sony Alpha mirrorless camera for professional photography and producing video projects. While Sony did not reveal pricing or specs, the drone is is said to be shipping sometime this spring. The quadcopter design shown during the all-digital CES featured two landing gear extensions that are designed to retract during flight so they do not get in the way of shooting stills or video. Continue reading CES: Airpeak Drone Designed for Capturing Photos and Video

Twitter Intros Ephemeral Tweets, Gathering Spaces for Audio

Twitter is launching Fleets, a feature that allows users to post photos or text that will disappear after 24 hours. Snapchat pioneered the ephemeral post, followed by Instagram and Facebook. Rollout of the Stories-like feature is moving forward, but has been scaled back as Twitter addresses “some performance and stability problems.” The platform’s “global town square” continues to be its “marquee product” but, said Twitter director of design Joshua Harris, the Fleets feature creates a space with less pressure for users who lurk but don’t post. The company is also testing Spaces, a new audio feature similar to Clubhouse, a startup that debuted earlier this year. Continue reading Twitter Intros Ephemeral Tweets, Gathering Spaces for Audio

Apple iPhone 12 Pro Max Receiving Positive Camera Reviews

The iPhone 12 Pro Max offers a number of firsts for an iPhone: the largest ever display, at 6.7-inches; the biggest camera sensor ever; a 5G radio and a bigger battery. At the same time, it’s not much more expensive than the next level down, an iPhone 12 Pro, with an added $100 for every storage level. The size of the phone — not just the inches but also the heft and weight — might be a downside for some users, but the iPhone 12 also comes with more choices, starting with the compact iPhone 12 Mini. Continue reading Apple iPhone 12 Pro Max Receiving Positive Camera Reviews

Apple Clips 3.0: New Interface, Multiple Aspect Ratios, HDR

Three years after Apple released its simple video creation app named Clips, the company is updating the app to Clips 3.0, now available in the App Store. Apple streamlined the interface with the intent of making it faster and easier to add effects. Also new are full-screen browsers on the iPhone to make it easier to record and include effects. Version 3.0 lets video creators access multiple aspect ratios, including vertical and horizontal, to accommodate Instagram Stories, Snapchat, YouTube and other popular platforms. Continue reading Apple Clips 3.0: New Interface, Multiple Aspect Ratios, HDR

Facebook Argues Breakup Would Be Costly, Weaken Security

Facebook’s lawyers, relying on research by the law firm Sidley Austin LLP, prepared a 14-page document that lays out its defenses against government threats to force a break from its messaging service WhatsApp and photo- and video-sharing platform Instagram. Congress and other federal antitrust regulators continue to investigate Facebook, as well as Google, Amazon and Apple, and the House Antitrust Subcommittee is expected to release its findings this month. Facebook’s acquisitions of Instagram in 2012 and WhatsApp in 2014 were vetted by the Federal Trade Commission. Continue reading Facebook Argues Breakup Would Be Costly, Weaken Security

Proposed Legislation Would Weaken Shields for Social Media

The Justice Department sent Congress draft legislation to weaken Section 230 of the Communications Decency Act, leaving Facebook, YouTube and other social media platforms vulnerable to legal action for content posted by users. The proposed changes would create liability for platforms that allow “known criminal content” to remain once they are aware of it. President Trump claims that social media companies are biased against conservatives. The platforms have not been protected against some civil suits. Continue reading Proposed Legislation Would Weaken Shields for Social Media

Pinterest Debuts Story Pins, Other Tools Aimed at Influencers

Pinterest is debuting two features intended for lifestyle influencers: Story Pins, which is similar to the increasingly popular stories feature available on Snapchat, Instagram and other platforms; and “creator profiles,” which allow influencers to show off their work. For Story Pins, which is already available to a select group of influencers, the creator can post photos and vertical videos with overlaid text and voice-over narration but doesn’t need to link to an outside website. Story Pins are not ephemeral, and followers can comment and react to them. Creator Profiles highlight projects via Story Pins. Continue reading Pinterest Debuts Story Pins, Other Tools Aimed at Influencers

Microsoft Develops Video Authenticator to Identify Deepfakes

Microsoft debuted a Video Authenticator tool that can analyze a still photo or video to determine the percentage of the chance that it is an AI-manipulated deepfake. For videos, Microsoft said the tool will work on a frame-by-frame basis in real time. The company’s tool is based on a FaceForensics++ public database and detects the “blending boundary” of the deepfake, with “subtle fading or grayscale elements” that may be indistinguishable by the human eye. It has been tested on the Deepfake Detection Challenge dataset. Continue reading Microsoft Develops Video Authenticator to Identify Deepfakes

Quality of Deepfakes and Textfakes Increase Potential Impact

FireEye data scientist Philip Tully showed off a convincing deepfake of Tom Hanks he built with less than $100 and open-source code. Until recently, most deepfakes have been low quality and pretty easy to spot. FireEye demonstrated that now, even those with little AI expertise can use published AI code and a bit of fine-tuning to create much more convincing results. But many experts believe deepfake text is a bigger threat, as the GPT-3 autoregressive language model can produce text that is difficult to distinguish from that written by humans. Continue reading Quality of Deepfakes and Textfakes Increase Potential Impact

Instagram Users Can Be Sued for Embedding Images in Posts

Instagram users have embedded images in their posts, believing that they were protected against copyright claims. Facebook now explains that, “while our terms allow us to grant a sub-license, we do not grant one for our embeds API.” In other words, a user who embeds someone’s Instagram post on her website has to ask the poster in advance for a separate license to the post’s images. Those who don’t could be subject to a lawsuit. Professional photographers will be able to better negotiate with publishers based on these terms. Continue reading Instagram Users Can Be Sued for Embedding Images in Posts
