kk... well, I'm starting to get a workflow down.

Here's my question. When there's a lot of changing light throughout the day, how do you setup your cameras and film?

Do you folks stick to a certain film all day and just underexpose or overexpose?

I've been in a lot of churches where 800 ISO would've been best but had a 400 ISO film in the camera and... well, couldn't easily change unless I had another camera.

Curious if you folks load up one camera with one film, and a second camera with another or.... something like that? I'm planning on using two 35mm cameras + 1 medium format (645) camera.
