Thanks for these suggestions! @dhopewell and @ColSebastianMoran, you guys are thinking along the exact same lines for I am.
This is actually a bug in the current version, it’s using color negative conversion for black and white images. Correct black and white conversion is coming soon.
This is the direction things are going, although it will be a few more betas before the UI for all of this gets built out. Everything that’s manually editable (film type, borders, exposure, contrast, etc.) should be adjustable after capture.
I’ve been thinking along these lines, and agree that this makes sense. I definitely want to provide as much real-time feedback as possible in the UI so you can understand what the automatic settings are doing and make correction as necessary.
