D800 , strange NOISE !
Hello everyone!
i'm so confused, i hope some one can help me...
Last evening i have made few shot of on spot,
when I loaded it in LR . I notice on the last raw`s some strenge noise or spots what imposible to remove like an noise. I gues it is hot pixels but , i was shooting maybe 30 minutes , and made 10 frames maximum..
And it`s not only in the dark tones.
I was shooting with 5000 iso and I couldn't see any hot pixels before. It was really clean. Now it over the all image ! on 100 % crop . Do any one have idea why it happend ? today in the mornig i have made few shoots and the image is clean again... :confused:

If those spots are always in the same place from shot to shot I might suspect some dust on the sensor. This doesn't look like hot pixels to me. If the spots are in the same spot try blowing off the sensor.

those spots (dots) has different color : red , blue , white , and you can see them only on 100% zoom .. :-(

It sounds like hot pixels to me, especially if they aren't always there (if they were always there, you would have stuck pixels). You might try taking some longer duration exposures with a lens cap on and see if they show up again in the same place. If you're getting them with normal (short) duration exposures though, it would probably be worth a call to Nikon.

Sounds like hot pixels to me too. There are some other mentions of this problem on the internet if you do a search. I'm not sure how many of them you're getting or if it's realistic to clean them up with the clone stamp.

For what it's worth, I've long experienced this with my Canon 5DII and it's just something I deal with in that manner. Long exposures in particular can have 2-3 dozen hot pixels. It's annoying but they're so small, it's a relatively easy fix with the clone stamp.

Its just part of dealing with digital cameras Ive seen this in all makes and models. Clone stamp and move on.
