I'm generally not a big fan of #Apple (understatement of the century), but I've read about the next version of #Safari officially supporting #JpegXL and I'm really glad that this is happening. I'm looking forward to the associated changes to #WebKit making it into the engine as it is used by other #FLOSS browsers too —and hopefully this will finally push @Mozilla into enabling #jxl in mainline #Firefox OOTB.

🆕 blog! “Selectively Compressed Images - A Hybrid Format”
I have a screenshot of my phone's screen. It shows an app's user interface and a photo in the middle. Something like this: If I set the compression to be lossy - the photo looks good but the UI looks bad. If I set the compression to be lossless - the UI looks good but […]
If I set the compression to be lossy - the photo looks good but the UI looks bad.
If I set the compression to be lossless - the UI looks good but the filesize is huge.
Is there a way to selectively compress different parts of an image? I know WebP and AVIF are pretty magical but, as I understand it, the whole image is compressed with the same algorithm and the same settings.
There are two ways to do this. The impossible way and the cheating way.
In theory it should be possible to tell an image format to compress some chunks of an image with a different compression algorithm.
And yet... none of the documentation I've found shows that's possible.
GiMP's native XCF and Photoshop's PSD files work; they store different layers each of which can have a different filetype. I understand that TIFF and .djvu also have that capability.
But those sorts of files don't display in web browsers.
That draws the JPG then draws the PNG on top of it. If the PNG has a transparent section, the JPG will show through. The JPG can be set to as low a quality as you like and the PNG remains lossless.
Embedded images are Base 64 encoded, which does lose some of the compression advantages. But, overall, it's smaller than a full PNG and better quality than a full JPG.
Look, if it's stupid but it works it's not stupid.
But surely there must be a way of doing this natively?
Quick note: If you follow me, you probably noticed that I post occasional photos. Unfortunately, the default display behavior on most Mastodon instances and clients crops many images unless you click on them. I hate this, as does every other photographer here, but it's not likely to change any time soon.
You can disable this broken behavior in the Mastodon web interface by unchecking a box under display preferences.
But in any case, please be aware you might not be seeing the whole photo.
@mattblaze Good reminder! I changed this setting as soon as I started using mastodon - so much nicer to see the full photo without having to click on it every time! 😁
#HitoSteyerl - Mean #images#ai
"#SenseTime is an #ArtificialIntelligence firm that, until April 2019, provided surveillance software to #Chinese authorities that was used to monitor and track #Uighurs; it had been flagged numerous times as having potential links to human-rights violations. It seems the combination of my name and face was not only used to optimize #MachineVision for #RacialClassification, but that this optimization was swiftly put into practice to identify and track members of an ethnic minority in #China. The fact of my existence on the internet was enough to turn my face into a tool of literal #discrimination wielded by an actually existing digital autocracy. [...] We interviewed [...] S., a student who did an internship in an ai start-up that offered personalized luxury travel recommendations to the better-off. His company’s communication strategy emphasized automation, with a recommender system allegedly based on users’ preferences extracted from social media. But behind the scenes, it outsourced all its processes to micro-providers in #Madagascar. It did no #MachineLearning" https://newleftreview.org/issues/ii140/articles/hito-steyerl-mean-images
So many #AI bots being used to make new art by learning about other people's art, not enough AI bots being used to scroll through #images and craft helpful #AltText for people.
Over 30,000 archival items associated with scientific papers presented to the #RoyalSociety (London) are now available on the new 'Science in the Making' archive, covering 1665-1949. https://makingscience.royalsociety.org/
Includes original manuscripts submitted to the RS; correspondence; lots of #images (many never published, and in colour); and >14,000 #peerreview reports.
Essential browsing for historians of science, and not just science. (Search '#mozart'!)
Lately I have been seeing so many posts with images and they are not including Alt text for accessibility.
If you are posting images please always put a Alt text saying what is or what it's showing so people with disability can understand what they are seeing.
images of most common(4:3,16:9,...) image aspect ratios should not be disorted/ cropped to the point where it's unreadable/ unrecognizable in the thumbnail
