Question about Canon PowerShot A75 Digital Camera
A few days ago, I bought a new digital camera canon A75. But I find in some picture I taken by this camera at night with flash open there are some grey rings on it. I don't know if there is some thing wrong with my picture. Can you help me?
Perhaps your camera flash reflected off a glass window directly back into the lens? Many camera lenses will capture "ghostly" reflections of the lens elements when a bright light shines directly into the lens. If you aim at the sun, you may also see spots or rings. Depending on the makeup of the camera lens (number of lens elements, types of coatings, etc) you may see spots, crescents, circles, or blobs of irregular shapes and colors in the final photo. Experiment to see if you can cause this behavior again, but don't look directly into the sun. Some photographers like the effect, others don't. Cal
