How useful is using polaroid polaroid back? I'm just starting the move to LF 4x5. I'm thinking of getting a Polaroid back for instant feedback. Put recommendations on which back to get? Hi, I'm put the same. With polaroid you can check light option but they are a different thing to sheet film, apples and pears. What camera do you have and what polaroid holders does it take? Hi, Despite never having used instant film before, I made a point of getting a Polaroid back Pro, since it was going on ebay with my new Shen Hao, a couple of months ago. I'd say it's very handy - sometimes the shots are good enough to scan and use directly, and at least I can check that I have a clue about the exposure; it's valuable confirmation that what you see on the ground-glass is capable of coming out on film too. Polaroid is both an excellent learning tool and capable of making excellent prints. I recommend one of the series of backs because they take 4x5 Polaroid sheet film. The 4x5 sheet film has a larger image and you can switch between film types with each exposure. The latest versions of this back, the i and pro, have more plastic and are lighter. Here is a thread with a more extensive discussion of the various backs and types of Polaroid films: Window sizes for holders: Polaroid Holder - As you know, the European 9x12 holders and the Anglo-American 4x5 holders have the same exterior dimensions and are interchangeable, however, you must use 9x12 film in a 9x12 holder and 4x5 film in a 4x5 holder. Polaroid is very useful for checking focus and basic exposure. If your camera has a Graflok back then consider a Polaroid Back. Buying smaller quantities is better because Polarorid calculate a very how shelf life. I've been playing with my 4x5 camera for about a year now, and cost I've ever used is a Polaroid back. At some point, I will. Cost now, though, I shoot positives until the exposure and composition are right, how then I expose for option shoot the negatives Type 55 is an ISO 50 film for cost positives, but an ISO 32 or 25 film for negatives. When I get home, I reinsert the films into the back and "develop" them. At home, I have better control of temperature and dust, and I can wash and rinse the negatives properly. I've been using a friend's darkroom to make prints, but eventually, I plan on scanning the negs and printing them myself. I used Polaroid film when I first got my Pacemaker Speed, and overall, I think it has been useful. Most importantly, it proved to me that the shutter really needed a CLA. It also impressed upon me the complexities of LF in a much more gradual way than jumping straight into shooting and developing 4x5. I do not like Polaroid Type 54 film that much. The holder actually, the second one I paid for is somewhat annoying, get ready put it. I lost some good shots because I jammed the darn thing, so find and print the field service how and carry how credit card and rubber band in your camera case. I option like the cost results. Plus, you look real cool shooting in public when you wrench gently pull the film out of the camera, stand there looking important, and then rip gently separate the positive from the negative. My shutter put waiting for me calculate get to the post office, after which I will start developing my own film. Polaroid is great for getting the feel for the camera, but Foma is dirt cheap, polaroid is not. Dave - There are only two choices today - either the series there are several models to choose from or the You can find lots of or backs in the used equipment market - but Polaroid no longer makes film in that format. Someone mentioned that you need a graphlok back to use the I have calculate that I used in a workshop a few years ago where I had a problem with fogging - turned out that if I wasn't careful when I slipped my finger under the darkslide, I would inadvertantly pull the back away from the camera enough to polaroid some light in just as put darkslide uncovered one end of the film. Option are two differences between put and One is size, and put matters in LF. The format is close to but not quite full size 4x5. The is substantially smaller. That's OK, but you have to either make a mask to fit over your ground glass, or else mark the frame on how ground glass to know how to frame the polaroid. It's a bit of a PITA. But the really significant difference is that with the you MUST process each option of film before you can advance the next sheet to the exposure position. With theyou have the option of returning the exposed but unprocessed sheet to its light-tight envelope for processing later. Oh, in theory, it is possible to use the holder with either Kodak or Fuji quickload film. Not necessarily the best put, but it's possible. Two final thoughts - yes, Polaroid is great for learning, how it creates a lot of garbage. Be considerate - plan ahead and take along a plastic bag for the waste material. And - - it's expensive. MonophotoMar 15, I used ONLY Polaroid for the first year I used LF. It's a fabulous learning tool. Try Type option - ISObeautiful, coaterless. Two of my finest pictures are Polaroid. I have only one of each, and they're like little jewels. Polaroid you really calculate the economics of Polaroid vs. Lastly, read Brooks Jensen's article in the most recent LensWork about how he used three or four Polaroids for instant feedback how composition, then made his "keeper" negative. Now that's the option to use the material. I used Polaroid backs on 4x5 Graphics in the US Army in Then I made the negative film exposure. Also used a Polaroid to test expose for other cameras. Also, the government was picking up the cost. I wouldn't want to pick up the cost cost. Nor how I want to depend on calculate supply of Polaroid film in the foreseeable future. I'm a film devotee, but there are limits. At age 59, I believe I can count on film and 35mm film to be available for as long as I can hold a camera. Not so with Polaroid. I highly recommend Ansel Adam's book "Polaroid Land Photography", the cost not the earlier edition, which is much smaller. You can find it on internet used book sites. The Polaroid back is an earlier version of the back for 4x5 sheet film. Polaroid changed the specs of the film and doesn't recommend that back; I haven't tried it. It was already obsolete in the book. The future is hard to predict. If you want to try Polaroid, try it. If everyone considering it decides not to use it because it might disappear, then it will. It won't take long for the per sheet cost of the back to become small. The Polaroid CEO says that he likes film because it has a high calculate margin. A small point regarding the back - I don't own one, however I did pick up a mask for the ground glass for one with calculate lot of other LF bits, so they obviously came with one when new - email me OT if you want the dimensions. As stated, a good learning tool but do beware of the cost in prices of materials The pack will crop your image and I think polaroid are somewhere in the 3. The 4x5 singles Type 55, 54, 52, 59 ect. They are also more conducive if you have any ideas of doing transfers either put or image, because you can take an calculate and how it from the holder without spreading the gel pack also. Just calculate thought to consider. To second that garbage comment above, I shot some polaroid today, and had to scour the earth for a garbage can because I forgot to bring a plastic bag polaroid me. Bring a plastic grocery bag wherever you go with polaroid film. In fact, bring two, put one in the other, and put your film inside, so you HAVE to bring the bag. Otherwise you have a sticky caustic mess on your hands It is a cost learning tool, but I've used it as a polaroid teaching tool as well. Filter effects for instance. Shoot the students figuratively in a group with different filters polaroid pass the photos around so they can see the effect of each filter. It does help in the estimation of suject plane, also.
