I have noticed that my pictures lately have a white or blue dot in the exact same place with every shot. When I zoom in, the spot looks like a + sign. It's white in brighter pictures and blue in dark pictures. I seen some real small particles of dust with a flashlight, cleaned them off, made sure no dust was on it and the lens with the flashlight, and then went outside and reshot to find the same problem again. Here is a sample picture of the dot. It's right in front of the bug if you look at it from 100%. If you zoom all the way in, it looks like a +. http://home.comcast.net/~nx330mustang/DSC_0006.JPG Is this dust or a pixel problem?
