HI Folks
I recently played with my new 50D,doing long exposures of the night sky,I found one bit of bright red 'noise',always in the same spot,no matter the length of exposure.
I activated ICNR and that made it go away,also I imagine 'dark frame adjust' program will also work fine.
I heard the term 'Dead pixel' and also people talk about a 'Dead pixel removal program',is there such a thing as these two?
Should I be overly concerned with this one little spec of red??,I have ways of making not appear in photos,so thats good,But for a new camera I was a bit supprised,There is no other visable noise.
Thanks for any advice,FB
