Last night, small fire ;D ;D I went out and tried out my new D80 - and 70-300mm Sigma lense. Im a noob, havent done much night stuff, or let alone anything with lot of flashing red lights. Can someone please tell me ( im a noob ) what the green dot is in one of the pics, its in a few, but not others, should i be worry about a pixel out? or is a weird reflection - I dont recall a cell phone tower, or anything there, but im gonna go back today and see. Please, suggestions, thoughts, advice, comments, all welcome.
