UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
I have been using the RGB tool more and more as I have switched to a monochrome camera. It has taken me a while to realize that I need to click the "new formula" button every time I change the preset if I want a re-calculated image. Now that I have the hang of that ...
What does the bg slider do?
I'm assuming that the first slide of each channel changes the weight of that channel (default of 1x is all channels weighted evenly).
The RGB sliders all make sense - the relative weights of each color being associated with the assigned channel.
And finally, how does the L slider work?
If I have taken LRGB at exposure ratios of 0.5:1:1:1 (e.g. luminance exposures of half duration of the R, G and B filters), then what settings would most closely represent what a OSC camera does with a typical Bayer matrix?
Thank you!
I realize that there are a few questions in here, but the ones I'm most interested in have to do with the bg slider and the L slider.
Any advice there? I'm just trying to get a general description of what those are doing.
Any additional advice / tutoring on RGB combining would be appreciated, too.
And the "0.51" above is really "0.5-to-1".
