Long Exposure Fixer


(MarkdenHartog) #1

I Find that doing long exposures always shows hot-pixels and they are a pain to remove. It Would be great to add in denoise.
It also happens on higher ISO with moderate exposures of 5 sec.

Camera’s I have used that have this problem include: D800e, D810, A7R, A7RII, 5DsR

Don’t all of those cameras have a ‘long exposure NR’ setting?

Yes they do. but it doesn’t work in the field. If you do a 15 min exposure you have to wait another 15 to let it do it’s thing… (black frame subtraction) and then they are still there.
I know I am not the only one with this problem, there has been lot’s of talk on the fora about this.


#4

Understood… which is one reason I sometimes choose to map them out manually. But without the dark map, how is the software to know which pixels are hot?

Is there other SW that does this correctly?


(MarkdenHartog) #5

No, and that is the point exaclty!
There must be someway to determine what they are. They are easy to spot with the eye, so why not software.

Anyway, this is like a feature request list and I would like to see this.
