I guess the subject title is self-evident, but I have a slightly embarrassing question on how to orient a Sinar P (one from the 70's, I think?) into the portrait or vertical orientation. I haven't been able to figure it out myself. Thank you in advance to anyone that can help.
there are 2 ways
the normal way is to unclip the back with that little clip on the top left of the rear standard
take off the ground glass/film holder and rotate it to portrait and clip it back on
another way is to slacken the rail holder and tilt the whole camera off to the side into portrait mode but this makes operating a bit awkward and puts the tripod off balance a bit which mat cause other problems
