[APh] Urgent. Artifacts when saving 32-bit image to TIF/JPG


Recommended Posts

I've got an image that I have to deliver any moment and I've got a problem that prevents me from doing so. Photo produces strange pixelated dots when I save it to TIF or JPG. It also happens when I convert the document from 32-bits to 16-bits or 8-bits. How can I fix this? Please see screenshot below.

Hey Alex, have you tried flattening your document before converting to 16/8-bit? The issue might be with an adjustment or live filter behaving differently when you convert the colour format. Are there are other details you could give us? What does your layer structure look like?

Yes, I tried flattening before converting to 16/8 bit but it didn't work. The artifacts still appear. :/

OK, is there any way you would be able to share the file to see if I can help further? If it's sensitive and privacy is required you could always private message a link on a sharing service (or we can send you a Dropbox link to upload it). Let me know!

Yes, it's a file for a client that should stay private so I will PM you a download link to the aphoto document. Thanks a lot for your help so far!
