There is also rubber that you can cast. Be careful, most of these resins/hardener compounds are highly exo-thermic while they cure, make sure you keep things cool or spontaneous combustion or deformation are possible.
Thank you for contacting Polaroid Originals. Unfortunately, that film is no longer in production. Polaroid ceased production of this film type years ago, and we are unable produce new film packs as we do not have the production machinery.
I don't know if they bought the patents for the old chemical process, and I don't think they are using it.
I myself think that the colors of the Instax line are fantastic, but if you want a larger image, Polaroid is yet again the place to go.
Polaroid runs about 2USD a picture (being 8 pictures by cartridge).
Instax Wide, by its B&H price, is around 0.9USD a picture.
I think Polaroid image size is 3.1 by 3.1 inches
Instax wide is 3.9 by 2.4 inches
Instax Mini film can be bought in a ludicrous number of physical retailers (considering the overwhelming ubiquity of digital photography now) - Target, Michaels, Urban Outfitters etc. Instax Wide not so much, another indicator of it’s increasingly niche little market.
I have the latest Fuji Instax Wide model given to me as a gift and it’s really not difficult to see why Mini is so much more popular - it’s significantly more expensive and much bulkier than the cute little mini models. I used it three times and then left it in a cupboard, it’s simply too large to carry around regularly.
Finally I’d argue the difference between 3.1 inches of image height on a Polaroid and the 2.4 of the Instax Wide feels much more different in person than the numbers alone might suggest. For me personally, I don’t think it’s a nice substitute for the look and feel of the traditional Poloroid format.
The Impossible Project had to do a lot of research and find alternative recipes to get the thing going again.
As for expensive, you can get single packs of 8 images for under $20. Not exactly cheap, but not prohibitive. If you compare price per image area with Instax, it's not bad.
Both come in at around 30 cents per square inch.
I still haven't bought a Wide camera, but even with all the Polaroid 600 cameras I have around, I think I'll buy one...
The Instax film, while I adore it, is almost too good at times. The colors are natural and spot on, of course there's always a fraction of the market that wants something else.
Thanks for pointing that out. I might get an Instax Wide. But I will try out at least one new formulation Polaroid pack in my 600 camera. I am curious about the colors. It's fun to not have only one formulation to choose from.
There's also the issue about lens quality. Some Polaroid cameras have very sharp glass lenses, while the Instax cameras have so-so optics.
It doesn’t help that square instax as a format is new and cameras compared to mini / wide are more expensive, along with the film.
I've toyed with the idea of putting the individual sheets into a sheet film holder for use in a Mamiya 23 camera. But it requires working in the dark and then repacking each sheet of film and running them through the camera to process with the rollers. For the same effort, I could be shooting regular film. Theirs is a much better solution.
The chemistry of those systems is incredibly complex, but the mechanism is simple.
