Re: Noise averaging handheld bracket

Noise reduction can be done by stacking in Photoshop too.

The amount of noise reduction is by the square root of the number of exposures.  It takes 4 shots to double the noise reduction from 2 shots, 8 to double it again, then 16 to double it again.

If you are doing long exposures in low light situations where noise can become a problem then look into astrophotography software.  It is specialized software that allows for dark noise removal and stacking for noise reduction.
