Thx for the explanation of what you were truly after...trying to figure out what European size format the camera which you had was.
I knew it was not the simpleton 'convert by 25.4 mm per inch' no-value answer which you were getting from many!

i was actually after 2 answers :smile:
will the metric film holders work with the imperial camera of nearly the same format
and then the equivilant to "how tall is the person with a size 7 1/2 shoe"


:smile:
 
Sure there is..........payroll tax,VAT,poll tax,ect...........you're just accustomed to it.
But it's the same price if you don't use it and no nasty surprises!

Can you please explain how this comment helps the OP in any way?
I think it's 'not at all'. But this is a forum and this is what happens!

Is it a conspiracy, or is it that we are simply all doomed?
 
I have a ruler with both. An inch is just slightly larger than 25mm. A inch to millimeter converter is quick to find on google.

Don't tell anybody but the US has been on the metric system for several decades. An inch is officially defined to be exactly 2.54 cm in length.

In Canada we buy 4x8 sheets of plywood that are 8 mm thick.

In the UK, we used to be able to buy timber in lengths measured in 'metric feet' - 300mm.

As a result of my livelihood I speak metric as well as 'murican. It's not the big deal some make it. My post was nothing more than a pun............apparently a poor one.
 
he borrowed a 5x7 film holder from a friend, the format is determined to be a 13x18 ...
i am kind of upset that i already have a 5x7 camera, this thing is a thing of beauty ..
 
5x4 film is not quite 5x4. Glass plates were the exact size, but when film came along, the same holders were initially used with a folded metal septum to hold the film. This required the film to be slightly smaller than 5x4 to allow it plus the folded edges of the septum to fit in the 5x4 holder.

The same would be true of all of the formats which were originally glass plate sizes.


US measurements? They're British!!

Steve.
You mean that Britain which had a chance to be part of Europe and is now all alone by itself?The sun has finally set over the British Empire!
