How many hot/dead pixels are normal?

[debeers]

I got my 10D yesterday. After doing some tests, I found it has 3 hot pixels on pictures with exposure over 10 seconds. Is it just normal or I'll get a better chance if get an exchange?

Are the dead pixels visible to naked eye when prints are viewed or photos are viewed in jpeg format?
If they are visible, perhaps you may want to get another.

If not, I wouldn't worry about it. Just enjoy the rest of six mega + pixels. A few thousand brain cells die each time we drink beer, but I got to have it after hiking.

And cheers to Sumerians (and their descendants, Iraqis) who invented beer and invented the sexadecimal system. Canon as well as all other cameras still owe a lot to them, because shutter speeds are measured in terms of seconds.

I have a hot pixel on my 10D that is barley noticable, but two clicks with the healing brush and it's GONE, typically you are only going to notice it if that portion of you photo is "pitch black" And like you said the exposure has to be 20 or more seconds, maybe I should be concerned but in the grand scope of things, it's a pretty small deal. Now if your picture looks like swiss cheese I would send it back.

My dead two or three pixels are blue? why? they appear on very underxposed areas even if I shot at a 200 mmmm tele-bearable speed (for example in the black silouetthe in a counter-light)

I found out I have 3 hot pixels, after shooting several 30 second exposures at a recent night race.

Long exposures are a once a year event, at most, so I can live with them.

Are these hot pixels on in-camera jpgs? I had some on another camera, but they disappear when using RAW files - seems the jpg conversion exaggerates them.

3 on a 10 sec. exposure (out of 6.3 million) isn't anything to worry about. Now 300 on 1/1000 - that's a problem (and still only 0.005% of the pixels).

A few hot pixels on exposures longer than 1 second is normal.
Also, shooting in warm/hot weather will make the hot pixels more visible.

I've never noticed any on my 20D, but I don't do many long exposures.
