here's your situation:

you're shooting a short short (3-4mins) budget of 2-2.5K with super 16mm. and almost NO dialogue (3 speaking lines from one character)

the majority of the film happens on a meadow and pond, you want to film walking in grass, outside nature atmosphere, water in the pond.

how much happens during the shoot, and how much comes in post with foleys?

i'm glad you opted for 16mm. what kind of camera are you using?

considering your sounds... i would prpbably record everything on location, but not at the same time as shooting.

I could produce a short soundtrack on a Sunday morning if I could get a DVD copy.
