Two and a quarter square camera?
Ben Norris
Please could someone explain to me what a 2 and a quarter square camera is.
I have been asked to take some shots by a friends dad and he asked if I had
one. I don't, I have a 35mm, I just wondered what the differences are
between the two and what a 2 and a quarter square camera is used for.
Thanks for your help

P.S sorry about the silly tagline, I don't know how to turn it off!

The 2 1/4 format is slightly larger camera than the 35mm. If you look at
the film formats from 110 or 16mm being the smallest image size and going
up the scale, you'd get 35mm next; then 120/220 (2 1/4); then 4X5; then
8X10; then 11x14. The 2 1/4 cameras use the next larger film size than 35mm
and yield a bigger negative or positive. You could look at some 2 1/4
cameras such as Bronica, Hasselblad, Pentax 6X7, Mamiya 645 to RZ67, Rollei
6000 series; these use 120/220 film and primarily yield 2 1/4 negatives.
The 645 yield 16 exposures on 120/220 film and the 6X7 yield 10 exposures
on 120/220 film. Finally, the term 2 1/4 relates to the size of the
negative when measured in inches - 2 1/4 inches across and down is
considered 6X6 or the square format. And to end - 6X4.5 relates to
centimeters, as does 6X6, and 6X7.
Hope I haven't confused you too much.
BTW: your 35mm takes a negative that is 36mm X 24mm; a square format camera
2 1/4 takes a negative that is 60mm X 60mm.

Beth:
A 2 and a quarter square camera uses 120 film to take negatives
2.25" X 2.25", or 56 X 56mm, usually abbreviated 6x6cm. It might be a
rangefinder, a single-lens reflex or a twin-lens reflex.
You use such a camera because of the bigger negatives, which, all other
things being equal, will give you sharper prints (of the same size) than a
35mm will. For 100 pounds or so you can get a used twin-lens reflex which
will allow prints as sharp as you can make using any 35mm camera, at any
price. Post in rec.photo.equipment.medium-format for more information.

2 1/4 Square refers to negative size in inches. These cameras use
120 size roll film, and make a negative (or slide) 2.25 inches by
2.25 inches. Hence the name 'two and a quarter square'. This is
in comparison to your 35mm camera with an image size of 1 inch by
1.5 inch. Hasselblad and Rolleiflex are two camera companies that
make 2 1/4 square cameras. Nowadays, it is often called 6x6, which
is the approximate negative size in centimeters.

"Two and a quarter square" refers to a camera that uses 120 or 220 film
and exposes a square area approximately 6cm X 6cm. It is roughly equal
to 2-1/4 in. X 2-1/4 in.
Cameras in this category include medium format SLRs such as Hasselblad,
Mamiya, Bronica, Pentax, etc., and twin-lens reflex cameras like Rollei,
Yashica, Mamiya, etc.
The square format is used extensively by wedding photographers and others
who want something other than the 4:5 aspect ratio print.

You certainly confused the *issue.* Beth's question concerned 2-1/4
*square* format. Any discussion of 6X7 or 645 formats was out of place.

This is 120 fillm and considered medium format such as Mamiya 330 or

Beth (I assume):
2-1/4 square is also called medium format, 6x6 (six by six), roll
film, and others.
Basically, it uses a roll of film that is backed by paper. It's a
very old system that was dropped by amateurs many years ago. Now it's
used almost exclusively by professionals.
The major advantage is a much greater size of negative and thus better
quality. I use both 35mm and roll film and rarely, if ever, use 35mm
for anything but casual, fun photography. When I do serious work,
it's almost always with the roll film cameras or even my 4x5 (again
the film is 4x5 inches in size and the huge negatives mean a much
higher level of quality compare to 35mm.
My major camera is a so-called 645. The negative is 6x4.5 cm. This
is smaller than the common 2-1/4x2-1/4 square format. But it's still
almost 3 times the size of a 35mm negative.
While I don't know the motivation of your friend's father, I might
speculate that he wants a professional quality photograph and knows
the difference. This might simply indicate he expects professional
results, or it might indicate that he knows that you can't produce
those results and is trying to intimidate you. You know the situation
and I hope you aren't insulted by my speculations.
In any case, I hope I've helped.
Good luck!!
