Is the aperture mechanism of a large format lens located within the shutter? If so, does that mean that when you buy a shutter (copal), it comes with its own ap erture mechanism? I assume that it does, but wouldn't the aperture have to be ca librated for the specific lens it was being used with it? Does this mean that th e aperture is fully adjustable from completely open to completely closed when yo u first buy the shutter, but is just not calibrated for specific apertures?
What about the apertures of enlarging lenses? Are the apertures limited to speci fically calibrated stops, or are they fully adjustable from open to closed?
