This film was made to look like a single take, where the camera moves seamless from room to room without any hard cuts. I decided to film this with my iPhone 12 on a DJI Osmo 3 gimbal, to be able to move freely in the cramped rooms.
The footage from the iPhone looks pretty good, although it needs a bit of work in post. Even when using Filmic Pro it still makes some annoying auto adjustments to the exposure.
