I work with a matte painter who paints in LOG under an ICC profile that matches our LUT. Once the LOG image comes in, Nuke converts it to lin space. This is important because if your painter paints in srgb and you bring in an srgb image you might want to change the structure a bit.
The tool converts to LOG applies the curve then converts back to lin.
It's pretty straight forward. just take a point value from the curve, enter those values into the corresponding inputs of the tool then click the button of the curve you want to add it to (thanks Ivan Busquets for the python buttons).
So far it worked great for me but I haven't done any extreme testing. I would be really interested to hear other experiences.
*there was a small lableing issue. in v2 but v2.1 has been fixed.
v2.5 - Now with built in color space conversion. If your painter paints in LOG set the tool to "LOG", etc..
