I'm putting this one up as I have a nude assignment coming up so I had to brush up on my techniques. The reluctant model needed a little persuading to let me put this photo up but it's tastefully done and thought it would be good for illustrating the technique, she agreed. This was taken on full manual mode at ISO100 1/200 sec f/8 at 48mm.

This was shot in a studio with a light either side of her but you can use any photo with a bit of variation in the shadows. As with most fine art nudes the photo was taken in colour but converted to black and white during processing. The effect used to get the shiny metallic look on the skin is called the Sabatier effect. Good old wiki has an entry about it here. As with a lot of old school techniques this can be replicated digitally but also is easy to over cook and time should be taken to get the effect just right.
Once you have your desaturated (B&W) photo add a curves adjustment layer in photoshop. A box will appear with a line running from the bottom left to top right. To the left of this there is a pencil, click this to draw your own curve, then starting at the top left of the box draw a smooth W shape. This will undoubtedly give you a very odd looking photo, if you then click on the points adjuster (icon next to the pencil on the left) you can then move the curve at each point, I remove a few points here by dragging them out of the window, you only need 5 or 6. Then it is a case of adjusting them until you get the desired effect. I'll repeat this can be very hit and miss but thats the beauty of digitally editing.
