Big shell, little shell

Two shells - both, I am told, varieties of the species Murex - laid on a mirror in front of a black background, with natural lighting.

"I have the world's largest collection of seashells. I keep it on all the beaches of the world...perhaps you've seen it."
Steven Wright (1955 - ), US comedian, actor and writer

-2.0EV looks fairly extreme, but the brightest parts of the shell were being illuminated by strong directional lighting to the point where they were being "blown" (recorded as pure white 255). This was evident when I reviewed the shots on the camera's LCD with "Highlights" selected. So, I took the EV down in steps to the point where this didn't happen, knowing that I could recover the detail in the areas of the image that were now too dark. I always shoot in RAW, and this makes the process easier. Thanks for your interest and comment.
