-- Sure. After you change the blend mode to difference, add an adjustment
layer above the 2 layers - Levels works well. First, it will show you
immediately if there are significant differences - you'll see some
data/levels spread across the horizontal axis.
To emphasize & exaggerate the differences, first move the gray slider
(gamma) to the left, then do the same with the white point slider. If the
two layers are identical, the image will remain black, with RGB values of
zero over the whole area. But any difference in pixel values, even tiny
ones, will show up clearly with an extreme levels adjustment like this.
Hope this helps.
