Hey, So last night was my first darkroom session with my new enlarger, the Leitz V35. The main thing I'm confused about are the masks that are controlled by little knobs below the film stage. There are 4 knobs, and they extend or retract masks from all 4 sides (if you had one, you'd know what I'm talking about). At first, I thought, AWESOME!, these are built in blades for cropping and what not. But that's not the case, because since they are a few cm's lower than the negative stage, they are out of focus and don't create a sharp line. So what's the point... is mine broken or what? I don't think so, but I'm at a loss.
