Use SKIV included in Special K Special K | The Swiss Army Knife of PC Gaming This includes a build of this which is the best HDR image viewer and HDR image converter period. SpecialKO/SKIV: Special K Image Viewer -- Strong emphasis on HDR capture, encode and tonemapping

For people who need an AVIF converter for HDR images, this supports exporting into many formats like JXR, HDR PNG, Jpeg-XL, and AVIF SpecialKO/SKIV: Special K Image Viewer (or at least the starts of one) (github.com) Unfortunately they don't release builds here yet, but you can get builds on their discord (FYI this is largely an HDR TV/Video Game discord not a photography discord). https://discord.gg/Ub93PynEEM

TBH while photoshop supports AVIF it's in the frustrating aspect of only being in Camera Raw for some baffling reason It's like every software company just can't get their act together and support shit properly. It's like the idea of cutting edge outside of 3D and AI is dead.

Edge now supports AVIF! (in the canary version but still) Things are finally settling on a format! AVIF image format | Can I use... Support tables for HTML5, CSS3, etc Alright no more F**king around, let us save in AVIF.

It's used more widely than AVIF or JPEGXL just cause xbox and nvidia use it for screenshots, and the native windows photo viewer supports it in full HDR. It is currently the only consumer level viewer for HDR images. There's likely more JXR images out there than AVIF and JPEGXL combined.

Now microsoft has added support for HDR wallpapers through JXR, is there a way to make this format outside of a game screenshot? NO! Announcing Windows 11 Insider Preview Build 25921 | Windows Insider Blog

I'm just saying from personal experience, saving the same HDR file from photoshop as an AVIF and a JPEGXL, the AVIF is a fraction of the size of the JPEGXL.

AVIF is much smaller than JpegXL though, especially for HDR images.

Agreed! We need more websites like this! Create and edit true HDR (High Dynamic Range) images - Greg Benz Photography

AVIF is MUCH smaller though, a AVIF is a small fraction of the sized compared JPEG XL.

So why is Avif not a saveable format in affinity photo?

Ok I didn't realize this before but I see why AVIF seems to be what people are leaning toward. The compression on those is INSANE. a 8-12MB HDR/whatever is like 200KB in AVIF. Photoshop supports this but affinity does not... At this point maybe I just need to constantly campaign for AVIF support. that would easily replace JPEG. It just needs broader support.

Also to be clear avif DOES work in most browsers just not edge. and does display as HDR in those browsers, it even works for text and such. Just check this out, but finding this kind of support on a publicly uploadable website is a pain.

Yeah there's lots of support in editing programs for all kinds of formats, the problem is consumer level. There's no solution for people to easily consume HDR images in a format that is also easy to create. JXR is the closest I've seen to at least beginning to solve that problem due to native Windows support and Xbox. Or at least help create some sort of demand for newer formats to be supported. If there was a bunch of awesome HDR paintings/photos out there that people wanted to see but couldn't without downloading the file, that would help create the demand. Photoshop is it's own shitshow cause it's not a default saving format it is a saving format ONLY in their cameraraw thing which requires steps to open up in a way that lets you save these formats unless you have lightroom. It's really stupid. Yeah I guess but that didn't apply to videos DX, there's plenty of video support but no images support. Can't create demand if there's no working solution in the first place. Is there even a way to make those? 🤔
