As stated by someone else, I do not understand the OP issue of this thread at all.
my issue is that a seller had a somewhat rare camera and he had no idea what the format was
he had no film holder to test it with, he measured it with a ruler/tape measure by the ground glass
when i asked what size the glass was. knowing the maker made mostly european format cameras
( cm, not inch ) and knowing the actual european formats accept inch format film holders ... i was
trying my best to deceiper what format camera he had from his 5 inch by 6 1/2 inch ground glass measurement.
i have both the export to usa versions of the 5x7 and 8x10 of this camera - 50 5x7s were made, and 5 8x10s
there were equally as scarce numbers of 4x5s made. while the european versions versions are very nice, too,
and supposedly plentiful overseas ( not here in the states ) but to be honest, i dont' want / need a 13x18 format camera ... i would, however,
love to have the somewhat rare 4x5 version of this camera, and i could have lived with it being 9x12 seeing it is a beautiful camera
and would readily accept my 4x5 film holders.
so, while i am well aware of filmsizes, how plates are larger than film, how graphic film holders (slotted ) don't fit international back cameras,
polaroid image sizes, the difference between a #500 and 545i/545ipro back, pack film, pack film adapters,
what the dimensions & / tolerances are of 4x5 even "t" distances ( having made my own film holders before ), how before a certain time period
film holders were proprietary depending on the camera manufacturer &c, ( takes another deep breath !)
..... what i dont' know is what size a 9x12 ground glass might be in inches
when i converted 5 x 6.5 into cm i got something that could have been close enough to be the european version of 5x7 ( 13x18 )
it is bigger than a breadbox, and smaller than a house ... inbetween the 2. sizes, and unfortunately depending on the maker it varies.
i am friendly with someone overseas with the 9x12 version of this beautiful camera ( what i had hoped it was ! )
and he measured his ground glass in inches for me and it was smaller than 5 x 6 1/2 so the mystery is probably over, i think it is probably a 13x18..
i appreciate everyone's help, suggestions, weblinks ( sorry for the frustrations ! ) as you helped me decipher what was a mystery. all the size info, plate info, format info is wonderful, and ...
if someone wanders into this thread, not wanting to know what i was after, but the differences between
large format stuffs, this thread will have a lot of interesting and useful info !
ANd some humor to boot ! a sense of humor is needed when asking questions
that are obvious to some, worded wrong, meandering, confused and vague to others
