... for those suffering Nex envy... :smile: Just give a try. On "another" forum... this interesting Ctein's article (i'd forgot) was linked: Now, a bit of an experiment based on that theory, Photoshop or equivalent needed: - get 5 identical shots in a row (high iso!) - have photoshop stack and align them, creating 5 layers - number one (background) remains untouched - the other four layers as mode=luminosity, opacity 25% ... done. look at 100% and compare noise with one of the 5 originals. I'm a bit busy to post examples right now, I've tried quickly with a series of B&W jpgs, and what happens to the noise is impressive... Hope it works with color too, let me know.
