This picture was taken with flash (pretty obvious...) with my Nikon N50 and I don't know why it's so reflected on the wall of our lobby... What should I do to avoid that? And this one came out with very dull colors (I am aware of the fact that the artistic level is below zero, but that is not my concern...). While this came out with very bright and nice colors IMO at least (once again, the artistic level is the least here...). I am using an UV filter on them all... Thanks for you input!
