    tips on deepening shadows in a clip?

    rbsiv

      I'm curious about the best combination of effects for deepening blacks and the other darkest areas of a clip whilst leaving the lighter areas relatively untouched. I have a bunch of material where the general brightness levels are perfect, save for washed-out 'blacks' that appear more dark gray at the moment. Any thoughts?

          The three-way color corrector can help you here as there are separate controls for Highlights/Midtones/Shadows

          - Just select the shadow option and you can adjust the input/output and gamma to suit. You can also adjust the range of dark to light that is affected in the shadow range:

            In addition to the Thrre-Way-Color you can also use the Luma curves effect (GPU accelerated as well).

             

            We would generally add Luma Curves to DSLR footage, as an exmaple.

              I'd probably just use the Fast Color Corrector and bring up the Input Level till the blacks reached 0 IRE.

                +1 on Luma Curves... or more specifically, +1 on RGB Curves. It does everything that Luma Curves does plus give you chroma control as well. That's convenient, since if you have to adjust the color of a shot (to a certain extent), you can do so with one effect rather than two or more. With CUDA acceleration, it's not too much of an issue, but my general feeling is that less is more whenever possible.

                  Interestingly (and I only just spotted this myself) there is a Luma 

                  Correction plugin (CUDA) which does this too (CC without the color 

                  section) - but you do need to bear in mind that the two plugins 

                  (curves vs CC/LC) work in different ways and will give you different 

                  results. Try both and use whichever looks best.

                   

                  Another tip while you're at it - it's useful to have a waveform 

                  monitor panel setup so you can see where your shadows are ending up 

                  and not getting crushed out of existence.

                    Many thanks for all the suggestions. Been doing a little trial & error, looks like the Three Way CC will suit my purposes for these.
