Almost all modern consumer and prosumer level cameras (and all of the mainstream SLR systems) use focal plane shutters. The alternative is a leaf shutter, which needs to be built into the lens. That was common on rangefinder cameras, and many medium format and all large format cameras use leaf shutters in the lens. > now if you'd use such a device in a moving camera so that the slit was > small, but the exposure was long (I'm not sure this can be done with > these shutter as they come) you might end up with an image similar to > what you'd get from a line camera.

You can't do that with any focal plane shutter I'm aware of. The curtains of the shutter move at a fixed (fast) speed. Sometimes you can see the effect of the moving shutter, e. g. when photographing a propeller-driven aircraft. -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
