|components of my new back for "modern" sheet film holders|
Time has come to construct a first model in life size. One of the things I don't make myself are the holders for the 4x5 inch sheet films. As this part, with its specific measurement is a given fact I have to deal with, I decided to start the 1:1 version with it's back, which I made for usage in horizontal and vertical position.
|almost ready for use|
This was not the first back I constructed and I already knew some of the issues that will need special attention, like: the film holder has to go in and out easily and in the same time it has to get enough pressure to hold it firmly against the opening where the image will appear. And it don't have to move while handling the camera or pulling out the dark-slide etc. In a former project I bent for instance an old spring of an alarm clock to give the right tension.
|it fits like a custom made jacket: easy and smooth|
My new design is even more practical, minimalistic and easy to use. Two rubber bands are strong enough to secure the holder on its position, pulling the holder in and out goes smoothly and of course without damaging the holder. At the end I will give the inside a lick of black paint.
|a simple but effective design|
My next step is to construct something like a box, where the back can connect to. This will be continued soon.
