Different export result from the final settings in the darkroom

[Vincent1712999]

Describe the bug

After exporting the image, the result differs from what I see in the darkroom. I have tried exporting settings from the "Intent" property (perceptual, relative colourimetric, image settings, etc.) but nothing works.

What modules are you using? Screen display works with a downsampled image for speed, and while most modules attempt to compensate for the reduced resolution, several are known to produce somewhat different results on the downsampled image (local contrast, tone equalizer, diffuse and sharpen, etc.). You'll know that this is the problem if the results match the screen display when you export with size set to screen resolution and "high quality resampling" set to no in the export module.

Current master has a new feature to toggle on full-resolution processing in darkroom view. It's a toggle because when enabled, editing will be just as slow as exporting....

I second what @ralfbrown mentions...set it to no for HQR and it will look more like the screen preview. Also don't worry about rendering intents with the default srgb profile as it doesn't support them you will get the same result. If you do want to see that then download one of the srgb profiles from color.org...they will support outputing to the differnet intents...

Thanks, @ralfbrown and @todd-prior , for the suggestions. I do indeed use the modules mentioned above, but whether I use HQR or not, the output is the same. The darkroom image is much darker, which I want to export in this situation. Can I deliver some other info that will help you understand this problem?

You could share an image and your xmp ... Also how are you viewing the result... maybe color management issue??
