Question

PNG Export doesn't match OCIO Document - Urgent

For years I've been working with a regular RGB/32bit Photoshop document with an Output Transform Color Lookup adjustment layer, and then an Inverse_sRGB Colour Lookup adjustment layer for compositing V-Ray ACEScg renders. This was due to Photoshop not using OCIO natively. This set up has worked perfectly for years but is now broken. Example of the correct colours here:

 

 

This is with using ACES Config 1.2.

 

With the latest release of Photoshop the Inverse sRGB adjustment layer now converts overbright pixels to weird colours (hot pinks, reds, or turquoises).

Now that Photoshop can create OCIO documents I've just tried dragging my layers from the regular PSD to the OCIO version. I've hidden my colour transform layers and the render looks identical to the non-OCIO document. 

However, when I go to File > Export > Export PNG the colours are thrown off and it way too saturated.

 

How can I get Photoshop to either stop throwing the colours way off in the standard PSD document, or how can I get the OCIO document to export a PNG with correct colours.

Help needed urgently due to client deadlines.

Photoshop 26.8.1

 

Why is it never easy!

Hi ​@PixelDeluxe, are you having this issue on the latest versions of Photoshop? When working in an OCIO document, exports will save the color in the current working space. If you are using a display transform to encode the data for PNG, you will either need to apply a display transform adjustment layer in the composite (set the OCIO panel view to ‘raw’ so as not to double-up the conversion on the canvas), or use the ‘Edit > Duplicate to Profile’ command. When using this command you can specify the output display/view transform, and embed a profile that matches the display colorimetry. For instance, you would use an sRGB profile when duplicating using the OCIO ‘sRGB’ display. Let me know if this is working for you or not.

I've rolled back to 26.5.0 and the issue with the colours being converted to weird colours has disappeared.

 

Can the devs please fix this bug, and also advise on the PNG export issue? I may switch over to the OCIO docs moving forward, providing they work correctly and simply.

Hey @PixelDeluxe, 

 

Thank you for sharing this color match issue with us. I wanted to check—have you had a chance to try Photoshop 26.9, which was released last week? If so, did you notice the same issue in that version?

If the problem still occurs in 26.9, could you please share a short video showing the issue and the steps to reproduce it? I want to make sure I’m not missing anything.

For now, I’m moving your post to Discussions to get more eyes on it. Let’s see if others have run into something similar.
