strange pixels showing up

[morgan]

I'm new to the R-D1 and I think I'm having an issue. There are red, blue, and green single pixels showing up in the same place across multiple images (although they are scattered across the image) even with different lenses. It's definitely in the image and not my monitor. Any ideas? Dirty sensor?

I believe these are "dead" pixels. If you have the latest firmware, then go into the menu and perform the dead pixel correction function.

Thanks, I'll gave that a shot once my battery recharges (I clearly need another)...

You need to do the dead pixel correction several times to clear all of the dead pixels. I usually do it about 5 times, minimum, to clear all of mine. That usually works 100% of the time.

Sounds like the problem I recently had, where I was getting colored pixels in the same place and thought that meant dead pixels. They were in fact not dead pixels, but rather hot pixels.

First, try to activate the long exposure noise reduction and see if that helps (it did in my case). If not, postprocessing may be necessary.

There are two free programs that I recommend for post processing hot pixels. Here are the links:

Looks like dead pixel correction thing cleared it up. So this happens often?
