Is there a way to select the difference between two layers?

I have a changed image I did, and the original.. is there a way with layers, to select the changes I made from the original image?

Not sure what you mean by "select the changes". You can set the Blending of the changed layer to Difference. Everything that you didn't change will then be black. You an make selections from channels that way I suppose or make a merged copy and make a selection from it.

I changed the layer to difference, but as I thought, you can see only the changed image parts, but you can't select *just them* in any way.

Sure you can. After setting the layer to "Difference", go to "Select - Colour Range", choose "Sampled Colors" and click somewhere in the black area. That will select everything that was NOT changed, so your last step is to inverse the selection.

I tried that, but some of the changes were near black colors, and they always were selected as well.

If they are changes, they should be selected, shouldn't they?

I finally just ended up redoing the changes, and this time saved them in a psd preserving the layers. There has to be a layer/selection combo to solve something like this though. I tried googling, but adding difference to the search gives you about 28,000 hits.

It is always possible to select only pure black, without any tolerance. Use the Magic Wand tool with tolerance set to zero (and "Continuous" NOT selected).

You should always save a layered editable file (psd) in case you need to make changes.

Yep.. usually, I do. But in this case I didn't, and the bottom layer was a copyrighted image, and not redistributable. (There was a possibility of it being so, but that changed)

Now I can supply the layers, and they can just add the original bottom layer themselves, and then save as a jpg. (It's for a 3d character's "skin") I was hoping not to have to redo it, but since I had the original and my redo, it was pretty easy to see what I had changed, and what I didn't. It was about an extra 1/2 hour's work, but still, it would have been nice to not redo it.
