You do indeed ask too much from a $20 plastic camera. You have to visualize the frame lines, just as you do with the focus distances....by guessing at them. I understand that the newer Holgas come w/ the frame lines previsualized on the film itself if that helps. I'm waiting for the newest, newer, most new, models that have the actual photographic images previsualized on the film. That way I can be done w/ the whole damn thing. Just buy your film, run off 12 (or 16) shots, frame it, and put it on the wall w/o all the hassle of going out to shoot things and stuff.
Truthfully, even if they did have them, do you think they would be accurate?
