I fucking love using all of the graphs. learnt how to use these well and I have realy improved my game as far as the quality of my footage.
Heres an example of how my left screen always looks when I edit. This is for a short film Im working on, I color corrected, graded and added a practical effect on the walking signal.
I use the waveform monitor to place my black limit, vectorscope to see what direction to compensate color to have a balance that I like. I use the histograms and waveform a bit deeper than most people, and this is huge for me, I use it to know when my colors are blocking.
Glad do see people are using this, or even know what they are!
