I have an old crown graphic that I've been using every now and then for the past year. 4x5 is alot different than 35mm or MF, but I do like using it. What bothers me though is changing from the ground glass to the film. Not only does it take along time, but I worry about the glass getting damaged. In a workshop some time ago I remember the instructor showing me a large format camera where the film plate slipped in front of the glass. If I get a new camera I'd like it to be a field 4x5. Does this feature exist, am I remembering correctly? Sorry this is such a stupid question, I don't have much LF experience.
