Staff Ash Posted January 4 Staff Share Posted January 4 Apps: All Platforms: Windows, macOS and iPad All Affinity apps now support import and export of 32bit HDR PNG files, as described in the PNG specification (3rd edition). Both PQ and HLG are supported alongside full / narrow range and a full set of primaries. Files exported can be used directly in video editing applications or shared on the web (Chrome now supports HDR PNG files). In addition, legacy PNG and TIFF files exported from Photoshop with CICP data embedded in an ICC profile are also able to be imported.

MikeTO Posted January 9 Share Posted January 9 Incredibly trivial, but in the 2.4 feature list announcement, PNG Third Edition is spelled Addition.

NotMyFault Posted January 9 Share Posted January 9 I would love to see the ability to export PNG above 32767 pixel count in x/y direction. The current limit is very unfortunate. All pNG above 32767 will get silently downscaled.

NotMyFault Posted January 9 Share Posted January 9 I Exported a test file having SRGB linear profile without embedding the profile, using ICC profile from document The export PNG shows a different profile BTU 2100. This seems like a bug.

ashf Posted January 11 Share Posted January 11 I didn't know that PNG has HDR mode. Just wondering how many people are using it? Can't PNG be replaced with JPEG XL? Quote Link to comment Share on other sites More sharing options...

Can't PNG be replaced with JPEG XL? It was introduced last year: https://www.w3.org/TR/png-3/ So far, FCPX and Davinci Resolve appear to support this (I haven't tried other editors yet), as well as macOS Sonoma and various web browsers, so it's getting fairly decent adoption. It looks to be a good solution for interchanging HDR broadcast imagery in a lossless format. OpenEXR is supported by most NLEs but has non-user-friendly colour management. JPEG-XL was possibly going to be a good solution, but Chrome dropped it (not long before/after we released V2, I think) and support for it isn't widespread. The cICP chunk in this PNG format allows the image to be tagged and processed with various video-centric colour spaces, which is more robust for broadcast workflows where the imagery needs to integrate seamlessly with video content, rather than being dependent on ICC (particularly for HDR content where you have HLG/PQ colour spaces with different transfer characteristics). ashf, tzvi20, B0R10N and 6 others 7 2 Quote Product Expert (Affinity Photo) & Product Expert Team Leader @JamesR_Affinity for tutorial sneak peeks and more Official Affinity Photo tutorials Link to comment Share on other sites More sharing options...
