Lovely photo Thank you for your B'day wishes yesterday :)

There is very little PP, I will get to this in a minute. In this case, I used the storage cardboard cyclindre and I placed the flash in front of it. It basically created a tunnel for the light, this is the reason it looks almost circular. Then, I composed to make sure the hand was where I wanted. You can see the original shot in my "concept" gallery. The post processing is easy I think however I use Picture Window Pro 4, here are the steps;
1. Create a contrast mask using curve
2. Sharpen the image two time using unsharp mask radii=2
3. Apply filter using the mask, filter with 50% gray (I think "multiply" in PS would create the same effect)
4. Increase saturation, adjust color of the resulting image.

Shooting time: 15 minutes
Computer time: 5 minutes

I hope this help. Cheers - JY

Nice Shot. Was that the actual lighting or PP?

This takes me back to when I was 13 years old and studying technical drawing at school! Another great hand shot.

Another interesting hand shot -- which you do so well!
