very interesting. I do not use that. i use a variant of laplacian image blending
posted about it here: discord.com/channels/270023348623376395/1260727356746764308/1342984912009171025
Here is another really useful color corrector.
It has the usual hueshift stuff.
but it is the along/perp stuff that makes it really neat. You select a direction. (say the classic teal and orange) then you can increase saturation along that axis and reduce it in the perpendicular axis. then if the image it too orange you shift the whitepoint towards orange to get the teal orange balance more centered.
I made this one for nuke a long while ago and use it very often. So here it is now for houdini! thanx to @jake rice 😮 for pushing sideFX to fix the mat3inv() function 🙂
