[QUOTE="physics-fan3.14, post: 4983148, member: 19165"]I feel your second set of pictures are definitely superior to your first set. This appears to be a lustrous coin, which lends itself to the bright white highlights and blowouts we've been discussing. I'd say that your second set of pictures, however, doesn't really have "blowouts" - a blowout is a super bright white spot where we don't see any detail. In your pictures, you show brighter areas due to bands of luster, but that's expected in a high grade coin like this. I'd actually say your second set of pictures are really good (without having the coin in hand to compare). I'd be proud of them. To continue improving (because that's the point of this thread): First - what camera are you using? Second - what mode are you using (full manual, Aperture Priority, etc.) -> I learned about a year ago that using the "aperture priority mode" was the best choice. Third - what ISO are you using? -> I have learned that an ISO of 100/200/400 is best. Anything higher is undesirable Fourth - what lights are you using? -> you seem to have the lights worked out better than you did. I encourage you to continue playing with angles. Different numbers of lights and different angles work better for different coins.
