I just tested my s404 P&S and if I put it on 64 iso...I have one hot pixel showing. If I put it on the highest sensitivity...400 iso...ugh....I got all kinds....8-10 second exposures. I'm wondering on the high sensitivity about the relationship to digital noise and hot spots.
I ran the program from the link previously listed and it found a couple of dead pixels and about 25 hot pixels. I'm only noticing the one in the pictures I looked at though.
