Question: does anyone know where I can purchase instant NEGATIVE B&W film FOR MY Polaroid Pro pack?
Document: This is the only instant B&W; film left on the market. It's the intended film for the Polaroid Swingers, 100-400 series, Colorpaks, and other cameras that can use it. The whole purpose to the 3000 speed film was to get a superfast ISO with a narrow aperture and thus make a "focus free" camera.It can be used in other cameras that are adapted for pack film or used the color film only--but then it's almost too much of a good thing.
I am giving one star because I was told this Fuji instant film would work for a Polaroid 600 camera but it does not. I have not actually used the film to know it's quality because it doesn't fit said camera.
I bought both the FP-100 and 3000. Maybe I just like B&W more or maybe the 3000 iso isn't that bad. But the picture came out great. I loved the result and its a hell of a lot cheaper then SX-70 or 600 film and you get 2 more shots than the others. I used a Polaroid Land Camera 104 with a external flash for indoor use. I love it!
Not much to say here since most people who buy this know what they are buying. I never shot instant as a kid because it was so expensive. My parents bought me a cheap Polaroid Swinger for a birthday without ever considering that I wouldn't be able to afford the film on my $0.25 per week allowance, nor did they consider that was the entire reason for the Swinger to exist. That is, to extract a kid's allowance or after sufficient whining the parents would kick in.
I have three different models of pack film cameras. This is is the answer, instant results, brilliant prints, dare I say better than the original polaroid film.
Used this film with my Hasselblad and Polaroid back and my Polaroid land 100. It is nice. The 6x6 positive from my hasselblad scanned in well. It's really fast film. Fun to use plus you get instant pic and the cost is about the same as it would be to purchase 120 film and have it processed. The bonus is having a print. This is a must have if you own a Hasselblad.
There is nothing like Fuji FP3000 except now-defunct Polaroid 667, which it replaces. Fuji has done a perfect job copying this very high speed instant film that fits millions of still functioning pack film cameras being used today.
When I heard that Fujifilm was making film for my Polaroid Land Camera I had to purchase some! Every picture turned out flawlessly! You won't be upset.
Still looking for a decent Polaroid camera to use the film with, but so far the images come out relatively clear. Hopefully I will find a better camera down the road that will give me the crystal-clear shots I know this film is capable of doing.
I recently discovered an old polaroid land camera in my closet that was in need of some film. I was inexperienced with this type of polaroid, so most of my pictures turned out dark or black. Once I got the hang of it though, my pictures turned out so nicely! I'll definitely be getting more in the near future since I now know how to use this type of camera.
Answer: The Polaroid makes a negative when you peel apart the images. After the chemicals dry you can scan the image (s).
