I was asked to please clarify the rules:
1. The photo must be taken at 50mm.
2. It must follow a Nature/Wildlife/Pet Photography theme
3. It must be taken during the 30 days that the challenge was created
4. It must be posted by November 19th 2012 at 11:59 PM (LOL, we can take into account your time zone).
That's about it - I think. Usually people ask better questions to things I overly simplify.
