Hi Photo Mechanic + Users >>>>>   JXL format is implemented by Affinty Photo V2 >>>>> 

This format will step by step be taken up by not just 75 year old bumbling computer amateurs like me...............   

Affinity Photo with their release of their major update to V2 will have already been taken up by many many thousands even though it was only released in November this year. 

Cameras are not so important.  It is in Photo processing that this format will gain traction. 

The Technical Team at Photo Mechanic + should  (with all due respect) consider rapid implementation of the JXL format so that users can see the JXL image and not a screen like the image below. 

A mechanic from a UK perspective is someone that fixes a problem when they find it during a service of a car etc.

https://www.irfanview.com/ This image viewer has  already fixed support and got a working PlugIn, (which is a simple download to instal the fix),  out for their clients.

When I process my images and use this new format, seriously, I need Photo Mechanic to display the image correctly !!!!!

Below is a section from an article I found quite quickly on the internet.  https://chromeunboxed.com/jxl-jpeg-xl-new-image-file-type-chrome/

What is JPEGXL (or .jxl)?

Not simply a modern replacement for the aging JPEG, JPEG XL is a far more compact image file with far more capabilities than the standard JPEG. The full breadth of things that JPEG XL files are capable of is very long and frankly over my head, but I’ll drop a few of the things below that you can expect from JPEG XL as it becomes more and more of a standard file type.

    High fidelity to the source image (matches human perception)
    Supports alpha transparency
    High-speed encoding and decoding
    High compression ratio (20:1 to 50:1)
    Improved functionality and efficiency over traditional formats
    Progressive decoding (by resolution and precision)
    Lossless JPEG transcoding
    Support for both photographic and synthetic imagery
    Graceful quality degradation across an extensive range of bitrates
    Perceptually optimized reference encoder
    Support for wide gamut and HDR
    Support for animated content
    Efficient encoding and decoding without requiring specialized hardware

Not only will JPEG XL be faster with better image quality, the files will be smaller and simpler to work with, too. While I don’t understand some of the more-complex decoding/encoding stuff that goes on with images, I can fully appreciate a file format that maintains a better image quality than the standard JPEG while also keeping the file size smaller with a faster encode/decode to go with it.   !!!!

Interestingly, JXL support is actually being removed from Chrome because "[t]here is not enough interest from the entire ecosystem to continue experimenting with JPEG XL"

Doesn't mean it will never be supported, of course. We'll see what the future holds.

Edited to add:   the new HDR capabilities of Adobe Camera Raw apparently ONLY exports in JXL
