A quote from the Daily Finance article: "But the film is more sensitive to heat and, as the photo develops, direct light than the original Polaroid products. For best results, Kaps suggests, a photo should be put in your pocket for a few minutes after emerging from the camera. And the probable result of shooting in the cold, Bosman remarks, will be photos that are almost whitewashed."
And this quote, from the BJP Blog: "I first took my SX-70 out in the street, removing the ND filter from the lens. Big mistake. One it was a bit cold outside (around 14 degrees) and Impossible did recommend shooting at temperatures of 17 to 25 degrees (Celsius)."
It's obvious at the outset that this, although being instant film, is not Polaroid. It's its own thing. I suspect the ISO of the new film doesn't match what Polaroid intended for the SX-70 camera, given BJP's remarks about having to fiddle with ND filters on the lens.
I think people will learn, over time, how to work with this new film, especially in regards to temperature. May be some new tricks that are discovered. The artisans and other process-oriented types will love the challenge of the new film. The real question, however, is whether it's successfully marketable. This doesn't look like the reliable Polaroid product that real estate agents, for instance, relied on for quick grab shots of properties. I suppose those days are over.
