So I'm ashamed to say that I've had my lovely Crown Graphic for over a year now and have not used it in all that time. (teachers are busy!) But I'm going to rectify that this week as I am now temporarily unemployed for a few months and have the time to really play with it. I've pulled it out and have been going over it, really thinking about what I need to do to shoot properly with it. I've done some research about Crowns (and other press cameras), but most information about large format largely ignores press cameras (due to their limited movements), and specific information about the camera just focuses on various parts of the camera, or shooting film with it. But there's so much more to it that that -- I haven't found any real information to help me with the following problems: 1. I have a top-mounted Kalart rangefinder on the camera which seems to be working and calibrated to my lens (135mm Optar). I know where the battery compartment is, but can't seem to open it -- pressing on either side of the 'door' does nothing, or both sides together, trying to slide it, etc... Am I missing something here? Although it's working I'd like to get in there to make sure there's no corrosion since I have no idea how long the battery has been in there. 2. I've just figured out (from a few posts and one guy on youtube) that once you open the camera you should pull the camera out to the infinity stops. Is that right? Is that only for the rangefinder calibration or is it necessary for making the best use of the lens? 3. If I don't extend the bellows beyond the length of the 6' focus marker, do I need to worry about bellows extension exposure? Do I need to worry about it if I extend the bellows to the end of the bed? If I do, is the measure from the ground glass, or the infinity stop? 4. Finally, the side shutter release (the one that would allow me to do 'press-style' photography) will not depress the shutter button fully -- it only goes about halfway. Is there a way for me to fix this simply, or will I just have to rely on the lens shutter? I've had some very limited experience with view cameras in the past, but not enough to help me with this. I'd appreciate any help people can offer.
