Default question about mf aspect ratio

I just got back my 1st roll from my Agfa foldup which is 6 by 6.
These tiny 4 inch square prints were exposed properly etc
but having used 35 mm I'm used to rectangular prints.

I can go up to 12 by 12 using 13 inch by 19 paper on my Canon S9000,
but my goal is larger prints in the papers format.

My question is , what format is similiar to 35, I've seen several
folders on ebay that are 6 by 4.5, anybody using this format?

Thanks for any info.

6x9 has the same aspect ratio as 35 mm, but it's not as common as 6x6, 6x7

or
6x4.5 ...

Here are the actual image sizes for 35mm and MF. There may be slight (1/2
mm) variations between manuafacturers.

35mm - 36mm x 24mm
645 - 56mm x 41.5mm
6x6 - 56mm x 56mm
6x7 - 69.5mm x 56mm
6x9 - 89.5mm x 56mm

Ya mean you shoot so perfectly that nothing can be cropped to match
rectangular paper?

format, aspect ratios:

6x9cm 1:1.6
35mm 1:1.5
645cm 1:1.4
6x7cm 1:1.3
6x6cm 1:1

So, take your pick. Note that folding 645 cameras have a vertical format.

Paper aspect ratios: 20x24, 11x14, 8x10, 4x5 are all about 1:1.25 (ideal for
6x7) and 5x7 is the oddball at 1:1.4 (ideal for 645).
Frankly, I would never worry about paper aspect ratios. Trim and be happy.

Actually, some of the old 6 cm by 9 cm folder cameras are close to the
same aspect ratio as 35 mm. Rather than try to match, it is easier to
acknowledge that some cropping is needed in many prints, and can
actually improve the final results.

A 35 mm frame fits better to 8" by 12" rather than 8" by 10". If you use
6 by 4.5 or 6 by 7, then that framing will often fit closer to 8" by
10" prints, just as an example. Using 6 by 9 would require similar
cropping as for 35 mm framing.

Also, I do use an AGFA Jsolette that is 6 by 4.5. It also has little
flip doors to allow 6 by 6 shots, though I prefer using it as 6 by 4.5,
since I do not like square prints. I recently changed out the
lens/shutter unit for a more modern (and useful) version with more
possible settings.

One way to tell if an old folder is multiple format is to look for two
windows on the back, though that might not always help you. The old AGFA
I have is somewhat of an exception, with the flip doors, since most
multiple format folder cameras used a mask. Often that mask might be
missing. Also, once the mask, or doors, are put in place, the entire
film roll needs to be exposed at that framing.

Ciao!

That certainly happens he the vast majority of the shots I take with my
Rolleiflex need to be printed square, since they were composed to be square.
With 645, most shots can be trimmed to A4, the main exception being vertical
shots with the 35mm lens that have too much forground and need to be cropped
to be square (i.e. are equivalent to shooting a 42x42mm square with a shift
lens.).

If you are using a flatbed scanner, 645 would probably not produce the
quality you are looking for. Get a used (they went out of production last
year) Fuji GW690III. It's not a folder, just a rangefinder. (I't called the
"Texas Leica". You'll know why the first time you see one.)

All of them? :-)

There is plenty of film to crop as you need/want. Just -one- of the cool
things about 6X6 is you don't have to bother holding the camera sideways.
Also you can crop the upper part off the frame and you end up with some
shift etc.

You can crop the Square Anywhere! (Wish I could remember who first said
that. David Vestal?)

Aw crap. There goes my new product: The Custom Hasselblad Tripod Head Flipper.

Thanks guys for all the responses!As I said, I am truly a medium
format newbie, but hopefully I'll learn fast!

I apologize for what probably was the dumbest question ever posed
here. And I'm especially grateful for the cropping advice. I forgot
how HUGE the negative is!
