No color adjustment. Black light turned whites purple and browns green. Most difficult task was keeping dust off the glass. I'll try a static sheet from the laundry to see if that helps. Also, I seem to be in a rut; I have to move away from small subjects with odd lighting. For a while, anyway.
Hi, Andi. That reflection is a very difficult, highly technical effect. Actually, it's just both surfaces of the glass the shell was on reflecting at slightly different angles. I didn't do a thing to achieve it. You have a sharp eye,though.
