Thanks for the demos Perry. Quick newbie question: is there a standard 709 conversion lut to use with the scans? The alexa 709 lut seems to work pretty well. I also get similar results with the "cineon to linear" and then "linear to 709."
P.S. I've got my first Bolex coming in the mail next week, so I'll probably be bringing some little projects your way the next couple months.
We don't use luts for grading at all, and we only work with film scans, so on our end, we have a pretty dialed in method for doing it manually.
I would start like this, on the flat scan, in resolve: Use Lift/Gamma/Gain controls, lower the Lift on each channel so R, G and B are all just touching the bottom of a waveform monitor (use the RGB parade to look at this). raise the overall gain up to about 90 or so on your waveform. Use the gamma and lift controls together to get the main blob on your vectorscope more or less into the center.
I usually try to have one black and one white in anything I grade, unless the shot obviously doesn't call for that. Something I learned in a photo class in art school that's stuck with me.
There's more than one way to do this, but this works well for us and it's quick. In most cases, this will get you an acceptable starting point for fine tuning in another node. We're running a render right now on our Resolve, but when it's done, I'll do this and post a screen shot of what it would look like. Only takes a few seconds.
