ALL OF THE LIGHTS: HIDING LIGHTS ON SET
We all hate it, it takes forever, but it can make all the difference between your project looking like it was filmed on an iPhone or on a RED - lighting. You have to balance that need of making sure your film actually shows up on camera and making sure the lighting looks believable. Nothing will take you out of a shot more than crazy white lights creeping in out of nowhere, ruining the illusion of normalcy in your scene. Luckily, Filmmaker IQ has put together a video explaining how to use and hide your lights on set.
Watch, learn, light. You're finished product will thank you for it.
