I’ve been using the new color balance rgb module recently and I think it’s fantastic. I really appreciate the fine level of control it offers. However, I’m a little confused over the handling of midtones.
The 4-ways tab is where colour is added, changed or neutralized, but the sliders are different to the master tab in that they are not separated by shadows, midtones and highlights. The power sliders seem to be more focused on the midtones, but there’s no masking for these ones and they still affect the entire luminance range except the extreme black and white level as far as I can tell. With the shadows and highlights, you can control where the effect is applied and the rolloff by using the masks tab.
But, as per the manual, global power is not masked, so I’m wondering if it’s possible to narrow/expand the midtone range without using parametric masks.
I find the masks tab incredibly powerful for shadows and highlights, but there doesn’t seem to be as much control for midtones. Is there something I’m missing or is there a good reason for this?
