JPEGXL literally is able to display images and colors that jpeg and png cannot (32-but floating point, layers, emission independent transparency, spot colors, built im depth maps). It’s not just about compression optimization. So for those use cases standard JPEG and PNG alone will never work. There are “updated” versions of JPEG that support some of these like HDR but those won’t work with any old browser either so back to the same issue.
Bottom line it can deliver greater quality at much smaller filesizes. Considering RAM and storage are more expensive per byte now than they have been in years, I think it's incumbent on everyone in a position to do so, to use those resources wisely.
WebP and AVIF and HEIC had similar advantages but also some disadvantages (honestly chief disadvantage to WebP in my humble opinion was that nothing except web browsers -- to this day -- seem to support it!).
Another important point in its favor is that JPEG XL is designed as a royalty‑free, open standard, and Google provides a perpetual, worldwide, royalty‑free patent license for its reference implementation.
Avoiding JXL (once the rollout is sufficiently complete) seems, to me, like still shipping (non-animated) .GIF files where .PNG is better and smaller.
I imagine the result of this will be social media platforms and such will deliver higher quality images at the same filesize. Currently for local storage any image format is mostly fine, but for web services the image size becomes a massive cost which is why they compress your 8MB JPEG down to a 2 megapixel crunchy mess.
It's trivial to make an image that you can see the 8-bit quantization in. Just make 256 vertical gray bars, equally spaced. In much of the image (usually the darker parts, but depends somewhat on monitor calibration) you will see the border between two values. Note that this is every single possible grey value in 8-bit RGB, so it is a proper un-dithered rendering of a gradient, and the borders you are seeing are definitely quantization artifacts.
Now, if you apply proper dithering, particularly on a high-dpi screen, you can make it look a lot better, possibly even undetectable.
And this is just with the dynamic range that is comfortable on a computer monitor! If we really want to represent vibrant images, then the glare of the sun off of shiny objects should be much brighter than the "paper white" background used in e.g. your word processor. It should be intuitive that the brightest highlight in a real-world image ought to be too uncomfortable to fill your entire monitor with...
Lastly, there's a question what and how the image gets to the browser. Sure for the images on the landing page for $LARGE_CORPORATION you have a graphic designer make everything look great, and since most people still have 8-bit displays, you'll want something that looks good on one. But what about e.g. a site for uploading photos? Are you going to quantize all of their photos before displaying them (possibly to someone with an HDR display)?
The cost of HDR displays is decreasing, and the data cost is minimal. (adding more bits to video actually decreases the size because the rounding errors get smaller)
Yes, a hdr photo in heif or jxl is a night and day difference. And if you apply any kind of color edits to the photo it stretches the colors to the point visible banding occurs on jpeg.
Yes, and image editors absolutely can. If JXL lets me correct over/underexposed images by default everywhere I find them then it's worth it even just for that reason alone
E-commerce is the important use case, particularly in goods where people care about appearance: clothing, cosmetics, food.
Things in these categories have colorful packaging with spot colors, metallic inks, coatings, as well as store displays with carefully designed lighting. The added cost is justified because it increases sales. It makes sense to carry that over online.
JPEG can represent "X" number of colours, but the human eye can detect Y>X colours. JPEG-XL can represent >X colours (but not as many as they human eye, Y):
JXL can do more colors than the human eye can perceive. Some chunks are out of range when using current standards, but it can do other chunks at 100000x the color resolution your eye can detect.
It looks fine sure, but that doesn't make it good either. Are you going to lock display technology to 8 bit forever? Most PC monitors already match or exceeding that limit, phones especially. HDR is something that needs to happen eventually, and for that new format is very important
Don’t think there was ever a time since Netflix started streaming where they only licensed global rights to shows. For their own originals they get global rights but the majority of their content is licensed and has always been slightly different in different territories.
Agree with the premise but about halfway through the writing becomes barely readable AI slop in style. Be honest did you yourself read this all the way through before posting?
If you think he was significantly resourceful strapped making Empire and Jedi you are mistaken. At the time they were some of the most expensive films ever made.
Mostly self-funded too (a higher percentage for Jedi than Empire) so even in the original trilogy it was still Lucas signing the checks and making the ultimate decisions. Him being willing to delegate more in those days was personality driven rather than financially driven.
We should get rid of ramps and handicapped parking at grocery stores too. If it’s such a large market someone can start their own accessible grocery store…
