First Try. New Camera

I think they look good (but I'm not an expert). Maybe you can get some more light on the coins, to show off more detail? Once again, I'm not an expert and they're better than mine, so what do I know?

thanks! I dont think its the light, but it might be the exposure. It might not be long enough ill give it a try.

What mode are you shooting in?

I think you're off to a good start. These are nice photos. Are you using a tripod or other support? The focus appears just a touch soft which could be the result of movement, or of using too large an aperture setting in order to get a faster shutterspeed. If you can use a smaller aperture (higer f-stop) you'll get a greater depth of field, but you will definitely need a support for the camera to eliminate shake.

I see you're using a black background, which I normally prefer, too, but you will want to play around with other colors to best display coins of different color/composition. Also, black really shows any lint, dust, etc. which can be a detraction, so you might want to crop as much of the extraneous background as possible before posting photos.

These are all just my opinions, so take them for what they're worth! Or ignore them.
