This is an example video of how some of my shots messed up in high light areas. The zoom is just to enlarge the affected area and not in the original shot.
Shot with the 7d and Nikon 80-200 at F2.8 in M mode, ISO 200 and HTP turned on because I was going to do a lot of night shooting.
Not sure what caused this, whatever it is I hope someone can tell me. Otherwise I will need to do a lot of testing to figure it out.
