So, having scratched the itch, I also successfully tried the 35mm-in-120 project with the 6×6 Bronica SQ-A which gave a negative 1.5cm longer than the ETRS. I was still forgetting on occasion though that horizontal and vertical are reversed because of the way the film is loaded onto the Bronica back, resulting in some odd compositions. Then I had another thought (awful habit, must stop doing this thinking malarkey) the film back of the Mamiya RB67 runs in the conventional 35mm manner, lengthways, and the film back itself can be rotated to shoot the 6×7 frames in vertical format. The itch flared up again!
So, despite saying that this was to be a project that I picked up very occasionally, I found myself loading 35mm film into the somewhat larger film back of my Mamiya RB67. One thing to note however. The RB67 film back did not detect the presence of a film and so the first time I tried this I ended up winding the entire 35mm roll onto the 120 spool without shooting a frame. So, out with the changing bag and I removed the now unwound film from the back and rewound it into the original cassette. The solution was the multi-exposure mode of the RB67. In normal use this enables the shutter to be cocked without winding on the film thus allowing multiple exposures on a single frame but I found that by leaving the camera in multi-exposure mode I could still wind the film through without a problem. The longer throw of the 6×7 mechanism means a bigger gap between frames and potentially more waste but I still managed ten shots by attaching the leader of the 35mm film to an eleven inch strip of 120 backing paper to reduce wastage at the start of the film.
The film still needs to be removed in a changing bag (I transfer it straight onto a reel and store it in the developing tank) but that is still only a minor issue especially when shooting at home! I cannot envisage this being something I would spend a whole day doing but if I did for any reason the changing bag is light enough to tuck into a corner of my rucksack.
No one needs to read an account of loading the film, shooting the images (the rotating back on the RB67 and the horizontal orientation of the film were a huge help) or processing the negatives. The first thing I noticed however when removing the processed film from the tank was the bigger spacing, but then the length of each negative struck me. It’s only 1cm longer, but that is an increase of 1/6, almost 17% longer than the 6×6 negatives and over 50% longer than those from the 6×4.5 film back in the Bronica ETRS.
The negatives were scanned using my old Epson V550 flatbed scanner and the Vuescan software. Rather than lay the negatives flat on the glass as before I used a Lomography Digitaliza 35mm scanning mask to hold the negatives. The Digitaliza holds the negatives by the very edges leaving the sprocket holes revealed. I had read mixed reviews but thus far its proven to be effective and relatively fiddle-free. The loaded mask needs to be handled carefully as it is very easy to nudge the negative out of its magnetic grip – especially with a blast from a can of compressed air! I also varied my technique for converting the negatives into positives but that’s for another day.
Here’s to the next itch – I’m off to load a roll of colour 35mm into a RB67 film back!
