The desired location for the ground glass is easy to state. The rough side
should face the lens (normally, anyway), and lie at the same place as the
emulsion of the film during the exposure, while composing and
focusing. For normal film holders you must then measure (or look up
somewhere) the distance of the film emulsion from the surface of the camera
against which the front of the film holder is pressed (i.e., measure on a
film holder. I wish I could add a sketch here!!)
When there is no film in the holder, the pressure plate will be at the same
location as the emulsion when the film is later inserted. If you have some
odd film holder for which this is not true, just waste one sheet film as a
test and study object. One case would be somebody using a vacuum holder;
depending on the design, the vacuum plate itself could be somewhat removed
from the ultimate emulsion plane.

Hello:
This has probably been asked, discussed, etc. many times before, and maybe
I've already asked.
I haven't built a camera yet...still collecting parts and so on.
If someone can please refer me to a website that discusses the requirements
for spacing ground glass relative to the film holder focal plane, I will
have a 'permanent' answer. Of course, replies to the list are
appreciated...I think they get lost in my archives, and eventually when I
start thinking about how to do something, I end up asking again.
Since my wife I own a gallery frame shop, I have access to finished
mouldings that would, in my opinion, make suitable standards for a view
camera, and that's the direction I want to pursue.
I usually see requests for sources of camera hardware, presumably 'proper
hardware'...I am curious what people have adapted from others arenas to
accomplish rise and tilt shift. Cosmetics are NOT especially important to
me...I get satisfaction out of getting good results from ugliness.
Thanks
Murray
