I was taking some pictures of a storm going through the other day and noticed some white spots on my pictures, when I zoom in they look like little white crosses. After some research it sounds like they are hot pixels. This isn't only happening on long exposures or high ISO. How are they dealt with, can they be fixed?

It's not that unusual. I had one on my D90, but only on high ISO and it eventually went away.

First thing to do would be to see if the hot pixels keep recurring in the same place. If they don't, then it's just a matter of editing them out (if there aren't too many!).

If it appears in one place for a period of time, then you may need to get it mapped out.

Have you been using live view a lot? That can contribute.

Strange to say that I have taken time lapse movies with my wife's Pentax S6 over a period of an hour, leaving the camera hot to touch, and never a hot pixel at any time then or subsequently. I wonder why DSLRs are so sensitive?

I almost never use live view except for last weekend I took some portraits of my family outside and used it to set up the tripod, then I turned it off. The worst one is almost in the middle of the picture and is always in the same spot. Any clue what it might cost to have this fixed?

This requires just a software-update remapping dead pixels.
So it shouldn't cost you an arm and a leg.

I can about 3 on mine, usually red and blue maybe white.
Only really happens on high ISO's for me.
I ignore it these days and if its a real problem then i will Photoshop it out.
Don't normally notice it to be honest unless its a dark photo.
Shame Nikon didn't give us a function to map out the hot pixels ourselves, ive seen this function on a older E300 Olympus DSLR. That was terrible for hot pixels hence i didn't buy it..
Ive always wondered if there's a service mode on the D90, one of those hold a button down while powering up ones..
