For all of the people teaching filmmaking and videography online for free, very few have any real quality. For a documentary style, Philip actually has some quality to back his opinions compared to what else is out there. His resume/portfolio isn't incredible but compared to the thousands of awful "teachers" online he has some quality that makes him really stand out.
Okay, I'll bite.
Yes, of course you can use different things to cue your audience in that a person is evil, but if your goal is to use lighting it usually involves choosing a proper location to set the scene in to create the mood.
I would say you pretty much have 2 options: 1: use acting and color. or 2: do what the movies do and use the location and time of day as a storytelling device. How often do you find out a character is evil on a hot sunny day when watching a movie? Rewrite the scene to make sure the tone and emotion come off properly. Maybe if it HAS to be on a hot sunny day the scene takes place in an alley? Or the character has some sort of physical indicator. The location and set design play a lot into the lighting of a film, so when considering emotion of a scene the two should go hand in hand.
The genre of film will also help dictate how much room to play with light there is before it becomes "unbelievable".
I'm curious how the 10-bit video will be in reality. At 150 mbps that is a smaller data rate than a Pro Res proxy file at 4k...
I don't know anyone shooting Nikon that would be interested in this lens...I could imagine a Canon mount but these lenses appear targeted at FS7 and FS5 shooters who haven't gotten a lot of lens love.
