Ok, I put a hold on the digital tattoo thing, and now I'm doing 3d stereo photos. Sounds difficult but it isn't. It's easier if you have 2 cameras but it can be done with one, I know cause that's all I have. You basically take the left eye picture move a smidge to the right and take the right eye picture. This works better with a tripod but can be done without, again, no tripod here. So I load up the left eye image in the gimp, then drag the right eye image on to the left eye image. The gimp places the right eye image on a layer on top of the left eye image. Due to the lack of tripod I usually have to line up the images vertically and sometimes horizontally to give the subject the focus, hey nobody's perfect. Hint: set the top layer (right eye) opacity to 50% for lining up then return to 100%. After it's all lined up, the manual way is to increase the image "canvas" size by 200% wider and leave the height at 100% (click on the chain so you can change only the one). Then move the top layer (right eye) exactly the width of the original image to the right so you now have the left eye image on the left and the right eye image on the right. Then right click on the layers and choose flatten. I have written a script-fu script which I will post if DA will let me post a text file (i think you can?). This script does the last part with resizing and moving.
