Let's clarify two things first.

1). Noise averaging is usually referred to by the name Image Stacking. Noise averaging is an effect of Image Stacking.

2). Image stacking utilizes multiple exposures of the same exposure value NOT bracketed   exposures, that's HDR.

Software of choice for this purpose: Photoacute

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.

Re: Noise averaging handheld bracket

I'll grant you that a bracket refers to varying exposures. I contend that noise averaging is the right term as stacking can be for different purposes.
