So, I was screwing around, taking pictures of the ember on the end of an incense stick, and I noticed these bright splotches of light here and there in the pictures. I thought it was strange and set a 30 second exposure with the lens cap on and took a pic, and I got the same result. Whats the issue here? Does my sensor need a cleaning, or what? http://i16.photobucket.com/albums/b35/airsoftsilent/IMG_0449.jpg http://i16.photobucket.com/albums/b35/airsoftsilent/IMG_0456.jpg EDIT- being told by a friend that it's just pixel noise from lack of light. Can someone verify this?
