Hi, I was hoping to get some advice on green spots in my photos. I'm a relative beginner and just got myself a Nikon D80 recently. Was experimenting with night photos and found green spots streaked across one of my photo (shot with 50mm/1.4D, f/2, 1 sec, ISO400). However, I retook the same photo at f/11, 30sec, and there were no such green spots. f/2, 1 sec exposure (hv circled the areas with the green spots in white): <http://www.medioluna.com/images/f2-1sec.jpg> f/11, 30 sec exposure (downsized the image because no real problem, just for comparison's sake): <http://www.medioluna.com/images/f11-30sec.jpg> Does anyone know what the problem is? When I examine the latter photo in greater detail, I can spot similar aberrations, except they're not so obvious so I can live with them. However, those in the earlier exposure were very glaring. Is this a problem with the lens or the camera? What can be done to fix it? Hope for some advice. Thanks!
