Waaay back in the '90s, Polaroid made large-format (18x24" ISTR) instant film that you could shoot in a purpose-built camera/studio for US$25 a pop, at (e.g.) the Boston Museum of Fine Art. The quality was really, really good. They also made b+w instant film that did a pretty decent negative from MF film backs. It's these dumb, modern plastic toys with shit lenses, and grossly inferior 'reverse-engineered' instant film that suck dogs balls.
There's something odd going on. Maybe I should start a conspiracy theory. Apart from the cameras with tiny fixed focus lenses (more or less) which are a throwback to various points in the C20th, most of these ridiculously expensive toys appear to have all the build features of cameras that actually work. So why don't they? That said, it has been commented that the auto-exposure system on the expensive Polaroid I linked to is really bad. One wonders about the quality of other stuff like shutter etc. Of course, this isn't Polaroid the company that launched instant film. It's Polaroid the recent start-up under the steady hand of the Petters Group. (Yes, the Ponzi scheme that ended with founder Tom Petters in prison for 50 years amidst bankruptcies, drugs, ramapant fraud etc etc). Polaroid (mark 2) simply bought up all the licenses and trademarks.
Auto exposure of film is a solved problem since several decades ago. It was built into the cheapest point-and-shoot cameras, and performed pretty well, at least in daylight. I think the issue here is the film, poor latitude, stability, and qc in general? I guess it's some kind of a miracle as it is.
True enough. I think the point I've seen made in a couple of places is that either the components are of the lowest quality under a slick outer shell, or they have been incredibly poorly set up for use with instant film. Or both.*
Yes, everything you say about the film seems correct, although it's pretty piss-poor if a company at the forefront of film technology like Fuji cant get it right. And yet I've seen artefacts such as a starburst of white at the corner of some shots caused by poor chemical dispersal as the film is ejected, which is just crap.
*I take your point, in fact I think I said something similar at the start of this thread. That said, I am deeply suspicious of just how badly some of these things work. I mean, the basics of decent sounding medium priced music systems were known in the 30s and 40s, but that didn't stop Bose building speakers out of dollar shop speaker-units in budget chip-board boxes and snazzy vinyl wraps. A ton of pseudo-science and they convinced half the buying public that they were the bees'-knees of music reproduction.
