Originally posted by Alex645 As the term "Medium Format" is a relative and not technical term, I can imagine a few folks with a different definition than others. But I haven't seen that reference, even with 'googling' although if I did hard enough, there is everything on the net both fact, fiction, and editorials.
And although Wikipedia is not 100% factual, the consensus there is that, "Generally, the term applies to film and digital cameras that record images on media larger than 24 by 36 mm (full-frame) (used in 35 mm photography), but smaller than 4 by 5 inches (which is considered to be large-format photography)."
I could imagine these terms evolving since the introduction of various rolls films. Your reference from the early 40's may be the Graflex Speed Graphic format 2.25''x3.25'', which was a miniature version of their 4x5" camera and was considered medium format.
I have to tell you that press photographers considered the 2x3 Graphic to be "small format", and 35mm Leicas and Contaxes were "miniature cameras". You've read the literature from that time, I'm sure. The 2x3 Graphics were called "Baby Graphics", after all. Then, there was the in-between size--quarter plate, or 3-1/4 by 4-1/4, and press photographers probably (note use of speculative adverb) thought that was "medium format". A very handy size for putting contact prints into an album, actually. But Rolleiflex was the only game in town for a commonly available, high-quality camera that used 120 roll film, so the term "medium format" had not come into being. At that time, consumer cameras (box Brownies) used 120 or 620 film (which is the same size. They called those cameras...cameras. That was the most common default size. It wasn't until the 50's and 60's that 35mm became ubiquitous enough to become the default, and then we needed a way to describe how much bigger cameras that used 120 roll film were. The guys that taught me photography 45 years ago usually referred to 35mm as "miniature", even when holding a brick of a Nikon F with that enormous prism (well, enormous for a miniature camera
). They had learned their terminology in the 40's and 50's, when a working pro, plying his trade doing group photos and the like, used 4x5 Graflex cameras. When I was a kid, the commander of my Civil Air Patrol squadron was a working pro, and I learned stuff that 13-year-olds can learn. His gig camera was a Crown Graphic. But he brought a screw-mount Leica on trips with us. Great photos--but lots of flare. His lenses were uncoated, probably from the 30's. That was his hobby camera. Several of us were getting into cameras at that time, and all we could think about was an SLR--the mark of serious photography. He laughed at us. "How can you do serious photography with a miniature?"
I came to the same conclusion only a few years later, when in college I knew that if I was going to get pay photography gigs, I had better be sporting a camera that was bigger and more technical looking that Uncle Harry's Spotmatic or Yashica Mat-124. The Mamiya C3 was that camera for me, plus a potato-masher flash.
Wikipedia is just what one guy wrote that is sufficiently unchallenging not to compel another guy to replace it with something different. On the Large Format forum, we've had endless threads debating the different ways it might be done. Some argue for area--6x17 has more of it than 4x5, so it must be large format. Some argue for packaging--sheet film is large format and roll film is medium format (nevermind that 2x3 and 6x9 are nominally the same size). Some argue that if you can fill the dimensional capability of a large-format camera, such as 6x12 does with 4x5, it must be large format (but then there's the Brooks Veriwide). Some even argue (apparently with little knowledge of the breadth of camera designs out there) that large format is a view camera (with a little grace towards certain press cameras, but there it gets sticky) and fixed-body cameras are medium format. Fact is, when wanting to claim some marginal format is large format, the temptation is to find a way to define that something into the fold. We landed on 4x5 in full recognition that it was entirely arbitrary, based (just like that Wikipedia author) on what would draw the least fire. But draw fire it still did.
Of course, pursuant to your point, nobody these days argues that 4x5 is NOT large format. But the point being made was that it wasn't always that way. And who can resist a pointless but entirely fun history discussion?
