All you do is render two or three (Or More) images of the exact same scene, but render each one with subtle differences. In each scene the light, bumps, and textures can be set to slightly different variations and intensities. Each image can also re retouched differently. Try using two completely different body textures or subtly blur or at noise to one of the images. If you add another figure in one image but not the others it creates a great 'Ghost' effect. In Photoshop or Painter3D overlap all of the renders at various strengths of opacity(transparancy). I find this is a great way of creating fresh looking images when you feel like you have seen it all before. It's actually a very simple trick. I using it alot. No picture but try it out. Just in the mood to share idea, Anton Ps: My modem is still screwy.Sorry about any unreturned emails. I'm at my sisters this week but will be back soon :)
