Sensor Noise (green dots) on Low Light, Long Exposure Photos

[joenami]

Okay, so this isn't video related... but still rather frustrating. If you look in the darkened area of this photo, there are green dots everywhere. Anyone else seeing this?

i had these dots pop up before but not in the raw image... it was very strange. i edited the rw2 file in photoshop and never saw these dots, then upon exporting they appear, and I can't get them to go away no matter what during export!

:huh:

Hot sensor leading to hot-pixels. Shut it off, let it cool down. Turn on dark frame subtraction for long exposures.

yeah I've seen that on long exposures.
