There are two kinds of key lighting techniques we learn.
1. Short Light
2. Broad Light
In the above samples of a music video that Black magic provides as a practice. I found one single shot that can't be match to any other shots.
DaVinci is a such a great color correction, grading tool.
However, there are something that you can't fix. It's direction of the lights.
Out of total 8 shots. Only second shot is short lighting.
Rest of them were used broad light. I wouldn't judge this project as 100% high key project, it's because there are some 6:4 a little bit of contrast between close and far depth.
As a director, and cinematographer, you must choose only one theme/mood/tone lighting technique to keep your continuity of the shots.
It would be such a helpful to your DP, if you can actually tell them in advanced.
(Broad light/ back ground depth is short)**
(Short Light/ Depth is deep and far)
(Broad light/ Depth is middle)
(Broad Light/ Depth is close)
