Bayer CFA and drizzle versus combine RGB

Hello,

First of all, THANK YOU so much for this new version 1.077. The pleasure of processing our images is all the more pleasant.

I am validating a procedure to obtain the best possible treatment for color images produced using a camera whose  Bayer pattern is RGGB.

After having realized the "split channels" of my color images and in order to obtain the best "realize / ideal noise reduction ratio (ratNR)", I used the zero tab "Bayer CFA" where I used the following parameters and continued processing until integration:
* RGGB Pattern
* Adaptive Airy Disc Algorithm
* Force Bayer CFA

For stacking, I got the best results with "bayer drizzle 1.0" and "droplet size 2.59".

Thus, I obtained for each filter (R, G, B) three channels each having their own "ratNR".

For the combine RGB, I did some tests by considering all the channels R-c1, R-c2, R-c3, G-c1, G-c2, G-c3, B-c1, B-c2, B-c3 or by not considering only one channel per filter is the one with the best "ratNR" (eg, R-c2, G-c2, B-c1).

At this point, I wonder what is the best or the best strategies to test to take advantage as much as possible of the captures of our color images.

Is there a tutorial on this?

Tanks in advance and Have a nice day,
