Hi all, this is coming out of another thread where I was asking for C&C on this photo. After posting it up, someone made me realize this odd and very noticeable banding/quilt-looking effect in the green leafy background in most of the pic (but not on the flower at all; it is seen mostly on the left side in the green and also on the right side and bottom green).
Can anyone help me explain why this effect happened in this photo and shows very easily with the little PP tweaks I did? I am worried that it could possibly be a camera or lens issue but I looked through all my other photos taken with this body and/or lens, and I haven't really noticed it anywhere else (as far as I can tell).
The photo was taken in RAW at 200 ISO, and no other abnormal settings, just typical to get the right exposure, and a little cleanup was done in LR2. Taken with my EOS 50D and Canon 50mm f/1.8 II lens.
Exposure: 0.002 sec (1/500)
Focal Length: 50mm
ISO Speed: 200
Exposure Bias: 0 EV
