What type of images? What might be different about those particular images?
Apologies for the brief and cryptic question. Frustration.
This is a TIFF file. Originally it was a RAW image that had a preset applied in ACR, then a black and white preset layer added. Then a couple small edits with contrast, plus an unsharp mask and high pass, completed with the flattening of the image and finally saved as a TIFF.
I believe it may have been the flattening, but when I close the image and reopen it it only has one layer. I can go in and edit this reopened image in a new brightness/contrast layer, but hue/contrast seems dead. Unless I colorize the image.
I have a hue/contrast preset I like to use as well, and if I add that preset when the TIFF is reopened hue and saturation can be manipulated.
Your question is exactly the one I have been asking. Any help would be appreciated. Thanks for your initial response.
