Like the way you have used a shell to display them,
though the background drowns it out a little, I am not
very good at PS but had a little go anyway, hope you
dont mind?
adjusted the contrast and saturation a little, maybe a little too much
saturation?
This shows off the detail much better. Maybe macro is the way to go I too really like the use of the shell in the shot. Well done glad youre happy hope it gives you the desired results. Might try macro mself now never thought of it to be honest.
Yep, what Mark said, with shiny things, the reflections are what counts, looks like you’re using a light-tent or something similar. You might like to try putting some strips of black, or random dark bits of card at the sides of the tent, to give more depth to the reflections…
