I have noticed subtle changes of tone when flattening images in photoshop. Typically, the layers I have are a bunch of curves applied to various tonal ranges of the image - these I simply wish to flatten for the final master copy. Does anyone else notice this and any ideas about how to get around it?
thanks, paul & preston. working on tif in CS5, 8-bit. oddly, when i flattened a different file, it didn't appear to do it. dunno, it's a bit odd. the culprit is this image - or let's say, this is the image that i noticed it on.
you're wise to keep all the layers, preston. i suppose if i were to make significant changes, i'd consider re-scanning and re-processing from scratch!
Hmmmm, not sure what you might have had happen, Stuart. CS 5 and tif should be good to go. I work in 16 bit, but never noticed any issue with 8 bit in the early days of using PS.
I'm very weak in B&W, only done one to date. So, hopefully Preston might have other thoughts here. I think he asked about the color profile too, you might look at that too for additional information to share. I use Adobe 98.

It's possible this is a display/zoom issue. Are you viewing at 100%? If you do a before and after screen cap at 100% do they look the same?
PS could just be rendering the reduced screen view a little differently depending on whether or not there are layers. If you can identify a portion of the image that changes, and it doesn't appear to change in the 100% view, then that's likely the answer.
good points - i'll have a look at the zoom issue - could be related to that. i also used Adobe 98 as colour profile. thanks to all

I think David is on the right track. I noticed this with type layers that have effects applied to them. The effect seems to change when flattening, but as soon as you view it 100%, you realize that the flattening is accurate and it's just the downscaling on screen for viewing that introduces an artifact. It's an entirely different situation, but I would guess that the reason is the same.

Also, which version of PS are you using? And, which color profile is assigned to the image.
Just a note: I do not flatten my 'master file'. You might want to go back later and make small changes to the file.
