I doubt that anyone is interested but I am about to start a new project. I tried the 4x5 conversion of two different polaroids and they both worked peachy keen. However, my flat bed scanner really forces me to scan at the highest resolution to get a good sharp digital file. 4x5 x 4800 dpi swamps my computer. Still I believe the larger the negative the deeper the detail so... I began collecting parts to build a new camera. This time im going 3x4 actually 3 1/4 x 4 1/4 or maybe 3 1/2 by 4 1/2. Now I you are dying of curiousity right? OH you're not well tough you can close this, I am compelled to tell it all. I bought a couple of old 3x4 graflex film holders. Which are actually 3 1/4 by 4 1/4 at the paper opening but 4x6 outside diminsions. The film holders havent come yet so I'm sitting on dead ready in holding pattern. I am on pins and needles wondering if the camera will handle the film holder without a major overhaul. Even if it won't I can make cardboard negative holders which work just fine. They are my own design and I'm sure someone else could design a better one. However cut film is almost a thing of the past. That is pretty much why I have converted two cameras to 120 roll film and two that will accept cut up 120 film made into sheet film. 2 3/8 x 4 inches. So I have this lens.. It's supposed to be the best lens kodak made for the simi pro market back in the 1930s. It is a kodak f4 antistigmatic. When I got it the shutter was sticky so I had to clear that up. Now it seems to be working well enough. So I will have a supposedly nice highly adjustable lens on a polaroid frame with a rangefinder and cut film back. The lens on my roll film back is a professional grade studio lens from the forties or fifties. Stripped from a calssic polaroid 110. At the moment I'm bored waiting for the film holders to show up. If I could stand the thought of polaroid film, I would leave the back alone and have a fine polaroid camera for transfers. I just don't like polaroid film. Anyhow now you are as bored as I am.
