Am I right in thinking that the recommended process for monochrome camera images is to stack the subs from each filter first into an LRGB or RGB file all at the same time (not stacking them individually into master colour subs and then stacking them into an LRGB or RGB image), then split that LRGB or RGB file, make the background adjustments to those master colour channel files and at this point then recombine them into a colour file?

Am I understanding this workflow correctly?

Thanks

no - stack each filter, after having registered all subs to the same subexposure, to the same subexposure (so meaning pick one sub, L,R,G,B or whatever, as the registration reference for all of the different filter subs).

then do whatever you want to do to the 3 or 4 master images - deconvolution, linear noise reduction, etc.

then combine to RGB and process. process the L separately. then do LRGB combine, effectively replacing the L component of the RGB image with the processed L master.

Thanks Rob. This is what I was originally thinking, just wanted to make sure.

All the best.

no prob, sorry for the typo there "to the same subexposure" should only appear once :)
