High Key Abstraction

Another fascinating image came up on Nikongear again. I got permission to show it here as a very nice example of high key abstraction. ....

Sea Urchin:

Andrea commented about her photo:
"I found the empty Sea Urchin shell on the granite slabs at Schoodic Point on the Atlantic Ocean in Acadia National Park in Maine. The gulls drop clams, crabs and urchins on the rocks to crack them open for a tasty snack. (Poor Urchin !!)
The urchin shell had such intricate designs both inside & out.
I made several documentary photos with my 60mm f2.8 AF-S Micro Nikkor, but something so beautiful deserved a more artistic, impressionistic approach.
I tried some multiple exposures and various extreme exposure and colour effects. This high-key abstraction made via an overexposure of the inside of the urchin shell (followed by a white/black point reset in the editor) pleased me the most. BTW, it is not obvious, but the greenish areas are from algae in a nearby tidal pool."

Not much "trickery" in here. Just an interesting subject (and naturally: the eye to identify it!) and the idea to abstractify it through over-exposure.

Comments welcome.
