I'm interested in pulling out the L and RBG from OSC for processing. I've looked for tutorials on processing OSC images this way (I'm using PixInsight and relatively new to the game) but I can't find one that explains the nuts and bolts (I'm sure there are tutorials out there but can't find one). So my question is, at what step do you split out L and RGB to do the separate processing? For example - use the integrated file (just before postprocessing) or right at the beginning (split out each sub)?
Easy, although like everything in PI, obscure. ChannelExtraction and ChannelCombination. Some stuff is on the default top bar, but all can be done off the menus. The wrinkle is the (6?) choices in color space.
Generally it's done after calibration and stacking, I'm sure you can find all kinds of workflows. Part of the challenge involved in using PI to it's maximum capability, and likely user, setup, and target specific.
There's no cookbook. There are a number of competing cookbooks. <smile> I think this guy is the best guide to developing your own workflows for L and RGB.
A fine example of how the $250 financial cost of PI pales in comparison to the time spent learning how to use it.
