Hot pixels are photosites on the sensor that are, in layman's terms, more
sensitive to the light striking them, than average pixels. Therefore they
turn 'ON' sooner and tend to be more visible during long exposures. Cold or
dead pixels are photosites that are always turned 'OFF'. There are also
stuck pixels. These are photosites that are always 'ON'.
From my own experience, if you don't look for them you probably won't see
them.

Subject: What Are Hot Pixels?

I recall seeing some discussions about these things, but never paid much
attention to them. So now that I've joined the Pixel Parade, it might be
helpful to know what they are and if I should be concerned about them. Are
there "cold pixels" as well?
