Twitter will start labeling manipulated and deepfaked content

06 Feb

Twitter plans to crack down on ‘deceptively edited’ and deepfaked media content by labeling tweets that contain these images and videos. According to Reuters, the company also plans to remove edited or computer-generated content in cases where it may put someone’s privacy or safety at risk, suppress voters or cause ‘widespread civil unrest.’

Twitter’s decision comes ahead of the contentious 2020 presidential election season, which is expected to include huge quantities of manipulated and deepfaked content intended to shape the outcome of the election. Other major online platforms have enacted similar rules about deepfaked content, though some critics say they aren’t taking a hard enough stance against such content.

Facebook, for example, likewise labels fake or otherwise altered images as ‘false,’ but won’t remove this type of content unless it is a video generated using AI to make it appear that someone is saying something they never said. According to Reuters, Twitter will take into account the text in a tweet and ‘other contextual signals’ to decide whether a post will be labeled as false or removed entirely.

It remains unclear how Twitter’s platform will detect manipulated and deepfaked content.

Twitter rolls out Live Photo support on iOS, improved JPEG compression

13 Dec

Twitter has updated its platform with two new useful features for photographers: iOS Live Photos support and better JPEG quality. Both changes are live now.

Live Photos are a type of image that can be captured using an iPhone or iPad; in addition to the image, Live Photos include the 1.5 seconds of action that happened before and after the photo was snapped. In order to make it possible to share these images, Twitter is first converting them into GIFs.

To share a Live Photo, iPhone users must launch the Twitter mobile app and select the image from their Camera Roll. Once the Live Photo is selected, the user can tap the new ‘GIF’ option located in the bottom left corner of the image. This will result in Twitter converting and sharing the Live Photo as a GIF.

Converting Live Photos into GIFs has been the primary method used to share the video versions of these images. Lack of direct support on many platforms has forced many iPhone users to turn to apps like Lively. Twitter’s new support merely removes this time-consuming manual conversion process, enabling iPhone users to rapidly share their Live Photos with followers.

In addition to the new direct Live Photos to GIF conversion feature, Twitter is also now publishing JPEGs with their original encoding, according to company engineer Nolan O’Brien.This eliminates the transcoding and compression that obliterates image quality when viewed in full size. O’Brien notes that the thumbnail version of JPEGs will still be transcoded to cut down on file size and that only the bitmap encoding is preserved, not the metadata. As well, the new encoding preservation is only live for images uploaded using Twitter for Web.

Twitter for Web has supported 4096 x 4096 image uploads since last year, according to O’Brien, who details some upload scenarios in which the platform will still encode images:

Twitter now supports adding images and other media to retweets

08 May
Image by Twitter via The Verge

Twitter has announced support for adding images, as well as videos and GIFs, to retweets and quoted tweets. Users had requested this feature for years, but Twitter explained to The Verge that it was tricky enabling media comments on retweets and quotes while maintaining a logical design that viewers could readily parse.

The new support, which is currently rolling out Twitter’s mobile apps and mobile website, allows users to add an image, video, or GIF after tapping the ‘Retweet with comment’ option on an existing tweet.

The company has chosen a design that nestles the original tweet with a timestamp and thumbnail under the full-width media published by the user who responded to the original tweet. This design only appears on mobile at this time, however, and The Verge points out that GIF comments on retweets look clunky on desktop.

It’s unclear when the feature and mobile-like nesting design will arrive for desktop users. The new option is rolling out on Android and iOS now.

Twitter wants you to tweet more photos, makes its in-camera app easier to access

16 Mar

Twitter has announced a change to its iOS app in an apparent move to encourage the tweeting of photos. The in-app camera has received a redesign and can now be opened by simply swiping left from your Twitter timeline screen.

Once the camera has opened you can tap on the virtual shutter button to capture a still image or hold down to record video. There is also quick access to Twitter’s livestreaming feature. Location information and captions are overlaid onto photos and videos captured within the app and you can choose from a range of overlay colors.

Overall the new feature isn’t a groundbreaking change but it shows that Twitter is aiming to compete more closely with Instagram and other image-focused social media apps, most of which offer equally direct access to the camera app.

Twitter is using AI to intelligently crop image previews

26 Jan

Twitter added the ability to upload images back in 2011, and while many people take advantage of that feature, one of its big drawbacks is crappy cropping. As Twitter engineers explained in a recent post, the platform automatically crops image previews for the sake of consistency, but these crops usually focus on the center of the image… often at the expense of the photo’s subject.

A poorly cropped image may hide the most interesting aspect of the photo—instead presenting a glimpse of a wall, empty sky, or something else similarly boring. And that adorable photo of Fido is a lot less adorable when it’s cropped right through the center of his head.

According to Twitter engineers Zehan Wang and Lucas Theis, the company at one point used facial recognition to somewhat solve this issue. With that, the system would identify the most prominent face in an image and base the crop around it. The system wasn’t perfect, though, nor relevant to images without faces.

A better system, the researchers explain, is one that focuses on saliency—that is, on the parts of the image that are prominent and mostly likely to be noticed. In other words: the most ‘eye-catching’ part of the photo.

“In general, people tend to pay more attention to faces, text, animals, but also other objects and regions of high contrast,” the duo explain. While a neural network can be trained to identify the salient parts of an image, it presents its own issue: it is too slow to put into production.

However, the team found a solution to that problem—one that enables Twitter’s platform to immediately detect the most ‘eye-catching’ part of an image and then crop with that at its center. The end result are image previews more likely to contain interesting elements that, as demonstrated in the screenshots above.

Twitter began rolling out its improved image preview cropping earlier this week, which means all of those really pretty landscape photos and product shots that pop up on the DPReview Twitter should be cropped a lot better in short order.

Twitter QA: The Magic Lamp

07 Jan

I get Twitter upstreams pretty often, and enjoy seeing photos from Strobist readers and answering questions when possible. I don't do full-blown critiques or portfolio reviews because of time restraints and an utter lack of any qualification to judge other photographers on my part. But a pic and a Q? Sure, I'm down for that.

Reader Mans Duffani, from Benghazi, Libya tweeted the above photo—a beautiful portrait—to me. It's a great example of a strong photo that could have been made even better if Mans had taken a moment while shooting to consider the image from front to back. Read more »

Why I Moved Comments to Twitter

13 Dec

The traditional blog commenting format may be convenient, but it is in many ways a broken system.

The last couple of posts have been an experiment of sorts, deigned to help me regain some of my sanity. I have turned off comments and instead created a Twitter hashtag around which to group post-related discussion.

And if the early results are any indication, things are already getting better. Here is why I am not going back.
