About colour correction and oscilloscopes

I often use this filter with certain Panasonic cameras that are a little heavy on the red tones.

I use Panasonic cameras; this is a very useful heads-up for me to look into.
Thanks.

A better way of course would be a … Curves filter

RGB-curves, Saturation-curves

The three-wheel color grading is nice, but doesn’t give enough freedom. Could it be possible to have curve-based color correction tools? Similar in Gimp, Blender, etc. Thank you for all your work!

Curves filter possible?

One thing I miss during colour grading is using curves. Is this particularly difficult to implement as a filter - I noticed it wasn’t listed on the roadmap page. I have used levels, but with just three points (shadow, mid-tone and highlights) to modify the separate RGB and luma channels makes it harder to achieve a personal film-like contrast, compared to using multiple handles on the curves. Another thing that is useful is having a curves-specific eyedropper tool that, when clicked in the monit…

I am more comfortable with the “transfer function” conceptualization, as exemplified by the “Color:Curves” tool in The Gimp image editing software.
I have been wondering if it would be possible to build a filter which used this conceptualization, this set of controls (and maybe even the same software; The Gimp is Open Source) as a front end for the same underlying filters used by Color Grading and Contrast.
That would be a whole lot easier for me to use, and I suspect for many others like me.

The cheerleaders shout “Curves!”
…and the crowd shouts back “CURVES!!!”
