I do not know the name, but there is software that will automatically clone out hot pixels. As I recall it uses a blank black exposure to identify the hot pixels, and the just clones those pixels to the surrounding area in each exposure.

A hot pixel is the digital equivalent to a pinhole in the emulsion of film. Of course with film you do not get one of those very often, but on the otherhand they are not in the same place every time so it is hard to automatically correct them.

I don't have this problem with the DS2 as yet, and I don't want to.  How do I 
avoid it?

My D you say.
I have never noticed them before,but then it might have something to do with you shooting high iso and the background.Alot of my D shots have open sky and grass, so i might have missed them.

Dust i just clone out. I'd say do the same for the stuck pixel.

I'll have to look closer to my newer shots and see if i can see anything.

Quoting Aaron Reynolds <[EMAIL PROTECTED]>:


Dave, that's from your D. The spots I'm asking about are on the player's chin, on the jersey logo and on the Nikon sign. So they're not dust -- how does one get these bad pixels in the first place, and how does one get rid of them?

Poping in late on this one.

I don't see any dust Aaron, but i see 1 bad pixel, upper left.

Dust on my sensors shows up as dark grayish blobs. A good hurricane
blow seems to work best.

FWIW i seem to have more dust problems on the D than with the Nikons.

Here's a chunk out of the middle of a file, unresized, unsharpened,
uncorrected, compressed a little more for the web.  It clearly shows a
couple of the mean dusties I'm talking about (plus some not-so-bad
ones):

Is this out-of-the-ordinary for an *ist D?
