Hah! As you say, one man's micro is another's mega-budget! Exactly ten years ago I DP'ed a 16mm feature for a friend, and he took it all the way through post and music, right down to box art and pakaging for a grand total of 10,000 . This was a true 10,000 dollar budget, as it had VFX, original music, and nothing left to "improve" if picked up by a distributor. He literally had boxes of shrink wrapped product at the end of the work.
Now here's more interesting info... out of that 10,000 dollar budget, fully 7,000 went to Kodak, processing and telecine. So, in essence, it was a 3,000 dollar feature!
So, the "micro" budget of 150K to 300K is fully 15 to 30X more than we had to work with!
We've often done the thought experiment on what would have been improved if we'd had, say, 100K to work with? Well, the story and directing wouldn't have changed... nor would the format (16mm). We might have had a couple more grips, or a better lighting package (maybe a real DP instead of me), maybe a talent "upgrade" somewhere in the mix, but it wouldn't have been a significantly "better" film, IMO.
In fact, my firm belief is you either pay no one or pay everyone. For 10K no one expected to be payed (yet the main actors actually got stipends), but for 100K people start stretching out their hands for just compensation.
My friend set up a website to talk about his experience, with brutal honesty about the process...
