Just playing around with my kids batman figurine, some manual flash with home-made diffuser, 4 digital composite images, and a little fun time in photoshop. Thank you very much for viewing.
From the original file that I have, I don't see any banding issues on the sky but if it is noticeable due to the upload from flickr kindly accept my apologies.
Nikon D70, 50mm lens, ISO 400, f/4 at 1/125 second, SB-24 flash in manual mode, digitally composited using photoshop.
