So my D80 decided to get me a present for New Year i photographed the whole party, came back home, opened up the shots and noticed that most of them had a red dot on them in the same place. Higher iso images seem to have it in most visible way. Here is an example: WTF?! Photos are not spoiled since it is easily removed, but WTF? And what should i do about it? It appeared in the everning today. Morning photos were clear. I havent touched the camera between then. I tried wiping my filter, my lens and blowing dust of the insides. No chanhe.
