I had to borrow a friend's DSLR and 100mm macro lens, but I finally got the toning to show up right on this Ike. I've spent a lot of time trying- the toning is light pastel, and I either had to shoot the coin too dark or couldn't catch it at all with my point-and-shoot. I can probably still do better, but for now, this is a win!
Have you ever tried using axial lighting? I don't know of too many people who mention it any more. Chris
