The pic I posted would have been ideal if the background light wasn't there. That was my problem when I was trying to do this. I was using a small compact camera which meant putting the lens right into the persons face, it felt uncomfortable.
I tried my 70-210 lens, cant remember what settings but the end result wern't as sharp compared to the compact camera.
Either a macro lens or extension tubes are needed, I haven't got either so we've sorta forget about this project, for the meantime.
If I get back to doing it again with success I'll put some pictures on to show you.
