Don't know what you're doing now.
If you're working from customer snapshots, just rubber stamping them onto a larger background with soft edge blending has a lot of customer appeal. In general cohesiveness between the images seems to sell better than just stripping up a bunch of hard-edged individual images. Setting the rubber stamp edge as soft as possible is all you need. Of course I'm sure you are already compositing with one image per layer, lets you backtrack if needed.
If you're shooting the photos consider this. A local portraitist makes a mint with a very simple technique. He photographs people against either white or black backgrounds, then rubber stamps maybe 6 or so of these onto a much larger white or black background, so you see multiple images of the same person or people in the same large background. Most of the shots are full body. The most important ingredient is very dynamic action poses with jumping, gesturing, rather extreme in most cases. The individual images are sometimes presented at different sizes, so you get the impression of depth. Things like basketball players in action poses, ballerinas, cheerleaders, and of course kids, lots of kids...and you name it. Sounds sort of dorky, but I grudgingly admit the result is very dynamic and has super customer appeal. He sometimes creates family groups this way, let's him pick the very best pose for each person.
Then he puts these is the most awful McFrames you ever saw. Card card width gaps at the corners revealing MDF below, the works. At least I can feel morally superior about the frames.
