You can save your curves settings and apply it to other images..
But the curves tool in Leaf Capture 10 only corrects the "L" luminous(?) channel.
You can set it to show RGB channels, but you can not adjust individual channels.
it's this kind of stuff that makes me wonder why Leaf even shows the color channels if we can't correct them.
After all this is not new territory as photoshop has had curves for each channel for about a billion years and this is one of the basics of color correction and manipulation.
As far as I know Canon and Nikon are the only manufacturers that allow you to work a setting and apply it back to the camera. I know, with Leaf you can send it to a card or the digital back, but that always gets erased under pressure, so it's not really that great an option and you have to use V-8 which is limited to contrast, click wb and global color.
At least with Phase you can make your own presets that are very precise and save them in the software then apply then to each image as they load up and the Phase software is stable so it will work.
All of these softwares could use more basic film presets than just AGFA or portrait WM Y4 (what the hell is Portrait wm Y 4?).
Still, for skintones and an excellent starting point the P-30 is the best I have used because you start from a good first frame, rather than trying to correct out issues with wb and input profiles.
The cleaner you start the easier it is to get to final.
