Yeah, those sensors in the Nikons do that in certain conditions....high heat, longer exposures,
I have yet to document all the times it tends to happen. That's how I got my 2nd D200 for $150.
"DEAD PIXELS ON SENSOR" I couldn't order it fast enough. Now the joke would have been on me
if there had been a ton of em, and at all times. But I was pretty sure I knew what I was gonna get.
The D200 is the worst I have seen, but you won't see it much on the D90. But since I process files pretty
easily through Photoshop, I can take care of them on the most important files in about 15 secs per shot.
If I don't plan on printing them I usually blow em off. You can go to the menu and use both Long Exposure
Noise Reduction and High ISO Noise Reduction and see how you like what that does. It targets em pretty
well, but I don't use it since I fix em myself. i'd rather not have a copomputer fix my pixels, though I ought
to test it to see how much other problems it does or does not cause.
