I think the way you're taking what I'm saying a bit too, um, intensely. I mean that in a non-antagonistic way. But, look, everyone here understands there's more on the film than there is on the Instant, and that anyone would always try in the end to get the most out of the film. Of course.
Still, I don't ever like til people on set, hey, don't worry, it'll be on the film. Not at all, unless there's something exceptional I can't control or change. Otherwise, say if there's not enough light on part of the instant, or fill or whatever, then I change it til it is. (But this is just a preference of how to work, and is really no big deal if done differently by others; if someone does it differently, or more loosely, cool. But I grew up assisting and learning from a few very good commercial still life photographers, and I took from them a certain perfectionism in these matters. Bottom line, these sort of specific of the way I work really doesn't matter, not here.)
And for what it's worth. The Fuji instant isn't crap imo at all. It's actually remarkably good. I'm surprised, if you've used it, that you'd say that. Now the old Polaroid stuff was a different beast. A lot of guys shooting color I knew preferred it, b/c the Poloroid stuff, made the film such a treat when it came back from the lab, b/cit looked so much better. Whereas the Fuji Instant was so good that they'd get contact sheets back and the client would want to know why it wasn't as gutty and colorful as the Fuji instant. Lol.
Anyway, we all work differently and do our own things. There's not right way here. Imo. B/c, yes, I do see Instant film as an aid to my film work flow on commercial jobs. As I stated, it makes them possible (no proof film, then it'll be digi for the most part). Unless I have an extra assistant who can literally run some test rolls of film quickly as I shoot the job (a la Avedon), which is a good option in studio.
