Imprint size on Fuji film 6cm x 6cm

[Dan Berg]

As this question will show I am new to mf film and have a question.
I have a 6x7 Bronica GS1 and was loading the film back with Fuji 120 velvia 100 yesterday.
On the edge of the roll is printed Fuji 6cm x 6cm.
Are all transparency films square or will I get a 6x7 slide?
No size information on the box or film sleeve.

If the camera is a 6x7 you will get 6x7.

You will get 10 frames with 6x7 rather than 12 with 6x6.

Any 120 film I used gave whatever format the camera body had; a 6x6 body gave 6x6 and a 6x7 gave 6x7, though none of these is exactly what it says it is. I had a GS for a while (very short while). Film never came with any pre-set formats. Think in terms of the ultra-wide cameras... same film.

Thank you for your response. Just found it unusual to find 6cm x 6cm printed on the edge of the film.

That is unusual.  Usually it just says '120'.  But in theory, if you had the right camera you could make one 6x80mm or so image from the roll - there are no built-in dividers on film.

The only films I can recall that had edge-masks in the latter 20th century were the 126, 110 and dic formats from Kodak, the Instimatic, Pocket-instamatic and the Disc cameras.

For both 135 and 120, the frame size can be from quite small to the length of the roll.

For instance, in shooting 35mm film through my X-Pan, I had the choice of both 24x36mm and 24x66mm on the same roll. On my different 120 cameras, I had the choice of 6x4.5cm, 6x6cm, 6x7cm, 6x8cm, 6x9cm, 6x12cm depending upon the camera I used. That gave me anywhere from 16 frames/roll to 6 frames.

Some of the panorama cameras like the Fuji/Linhoff cameras would use even 6x17, about 4 shots per roll. Going to something like a Hulcherama you would get one shot and that wasn't for a full rotation. You almost need to run 70mm film for those specialized tools to use them well.

As long as the film (and most roll film is this way) doesn't have pre-exposed frame edges, frame length is dictated by your camera/back combo and in most cases, the back or camera will have some designation somewhere on it or in the instructions what that frame size actually is.
