Question about Canon EOS-20D Digital Camera with 17-85mm Lens
Posted by Anonymous on
It's a hot/stuck pixel. It's not dust. If it's always the same shade of white and on every shot it's stuck. If it's some shade from grey to white and only shows up on longer exposures, it's hot. Can't be fixed. Canon should be able to map it out, but I'm not sure of their warranty policy. Sometimes warranties on sensors specify a maximum number of defects. Very few, if any, warranty a sensor to be perfect, with zero dead, stuck or hot pixels. If you don't specifically look for it in a print, it's unlikely that you (or anyone else) will notice it.
