Actually, 2.25" x 2.75" for 6x7The nominal size is 2.25x3.25"
The best you can do is plan for 61mm. I'm not willing to pay for a copy of the ISO standard to obtain greater precision than that, but most secondary references, including this one...i am wondering about the entire piece of film that makes up the width of 120 Film.
Isn't it standard for all brands of 120.?...
That accounts for different manufacturers' image width, i.e. across the film's roughly 61mm width, variations. Different image lengths (perpendicular to the roughly 61mm film width) are entirely arbitrary manufacturer decisions made for a variety of reasons....The edge printing and the need to have unexposed area around the outside of the image area is part of why the actual image sizes vary from camera to camera...
For example, my Beseler 23CIII's "6x7" glassless carrier opening is only 53mm x 67mm. My LPL 4500II's "6x7" glassless negative carrier opening is 56mm x 69mm....It would be worthwhile to measure the "gate" of your enlarger's 6x7 negative carrier...often slightly different than the size used in the cameras.
I'd wager it won't measure anywhere close to the commonly used misnomer "120mm."...pretty sure the school has some 120 laying around. i can measure that.
That's funny.....though i would bet it is a common and intuitive mistake.I'd wager it won't measure anywhere close to the commonly used misnomer "120mm."
Because, like 120, that's the numerical designation Kodak invented for it many, many moons ago. 135 refers to 35mm film in a cartridge/cassette. The number of standard 24x36mm frames it's capable of is appended as a hyphenated suffix. For example, 135-36, for 36 exposures....why is 35mm film often referred to as 135.?
A better question is why is 135 film referred to as 35mm film?For that matter, why is 35mm film often referred to as 135.?
Right...i may have been unclear on that point.Re-reading the OP, it seems he is not interested in the 'frame dimensions' of the image area, but is more interested in the actual film dimension that is set aside for a shot to be taken.
A roll of Kodak 120 that I keep around is 61-1/2 mm (I do not specify decimal because I cannot accurately determine 61.4 vs. 61.5 vs 61.6mm, so I list a rounded (to nearest half millimeter) dimension.
OK, i will measure the Neg Holder for my enlarger.
This has been an eye opener for me. It never occurred to me that The Neg Holders, of the enlargers, would vary by that much.
Right...i may have been unclear on that point.
I am NOT worried about the size of what gets printed.....wondering about the size of the entire film itself.
I am making a film holder for a Pinhole Cam, and want the frame to be snug in the holder while it is in the camera.
