When I take digital photos in low light (ie. concerts) my pictures are turning out with white blemish dots all over them.
I got my iso set to it's highest (400), I'm using a slow shutter speed and I have the aperture set to auto. I'm taking close pictures with a high flash setting. The pictures are nice except for the white blemishes. These blemishes dont' show up under normal lighting conditions. Anyone know what's up? |

Do you have a polarizing or UV filter on (or any other, for that matter...)?
They do weird things in low light, methinks. |

Hot pixels.
Some cameras have a feature in their software to identify their CCD's hot pixels and then deal with them. This is not common, though.
If the pixels are appearing in images at normal lighting/normal speeds, you probably have a defective camera. But it's normal at ISO 400 in a long exposure with dark lighting for them to appear. Take any digital camera with manual shutter speed, turn the flash off and let it do a 2 second exposure in a closet, and the resulting image will look like a photo of a starry sky. |
