Hello all,


I went out shooting with my mother last night (me on a 7D, her on my older XSi), we were shooting long exposers if this makes a difference. When we uploaded the photos I found about a dozen pixels that we stuck on in every shot taken on the XSi. A couple red and a couple blue. I looked at some of my mother's older shots (normal exposure times) and found the same problems. Any idea what may be causing this? Perhaps any ideas of what I can do to fix it?


Thanks.
