Derek -- I'm assuming many of the animal shots are taken at a zoo. If so you manage to evade the various obstructions that routinely hamper me when try to get a clear shot. Kudos. Which zoo?
Thanks again Larry. Yes, they are faintly visible but I doubt that one would see them if one's not looking. I can't figure out where they're coming from. I took this image on my cellphone which is very unusual. It is in the original .jpg (still don't shoot raw on the phone). I haven't seen it in other phone images. It reminds me of scans of printed pages sometimes show bleed through from the reverse side.
Larry -- Thank you for the comment. The day we were there it was 105 deg. in the shade and it was only early May. Death Valley has lots of different "faces" and it's hard to capture them all. An earlier image that I've posted of Zabriskie Pt. was another attempt.
