Yes, I have Picasa, even had an update to it and I can find nothing to help me out. Is this condition called "flare". I have a Nikon HB-57 Lens Hood that Nikon says will: By reducing the amount of non-essential light falling onto the front lens element, lenses can better achieve their optimum optical performance, producing more saturated images. Use of specifically engineered Nikon lens hoods is highly recommended. In less-than-ideal lighting conditions, the performance difference can be substantial. Do you think using this will help avoid the condition I experienced?
