[QUOTE="rmpsrpms, post: 3068339, member: 31773"]For raw coins I put the coin on what I call a "transfer disk". I place the coin on the disk, then transfer it to the stage where I will take the picture. The disk makes it much more convenient for moving the coin around on the stage to get proper framing. One side of the disk is a true grey surface that is useful for white balancing. Other side is photographic black velvet light absorber material that the coin sits on. With proper exposure settings, the background goes "nearly" black. It often will show up as 2,2,2 or even 4,4,4 depending on lighting and settings. This is easily pushed to black by changing the black level to darken it a bit, or alternatively increasing contrast a bit. This method eliminates the need to do circle crops. It also more faithfully preserves the look of the visible edges of the coin, so they don't end up looking jagged due to cropping. I make these disks myself...PM me if interested.[/QUOTE]
