Electronic flash.... Bare Bulb = extra bulb on top of the flash that has no reflector so that the light goes in a 360 degree pattern. Bulbs ( 1 shot, gas filled..) had a turn on time. While I forget precisely, the M position allowed the shutter to start to open while the bulb was not yet at full peak output. Your shutter speed WAS an important component in the total light that hit the film,,, because the flash would last for many many milliseconds. Exposure is dependent on shutter speed, light output,, and f stop. X was for electronic flash. The shutter was opened and then the flash was fired when the shutter was (presumably) fully open. This works because even in the early days. The flash duration was like 1/10,000 or faster of a second. Therefore for electronic flash. The shutter speed is of no consequence... as long as the shutter is open when the flash fires. Exposure is dependent on aperture and light output. Advantage of electronic flash is that the ambient light in the room would be overpowered by the flash and the fact that you could use 1/500 of a second shutter speed ( we are talking here about leaf shutters) to underexpose. This would mean no ghosting effects from moving objects. Frank Filippone Red735i at earthlink.net I am thinking about somehow hooking up a small flash to the SWC for some indoor shots. (yes, I know flash is death) what kind of flash would work? I guess I will need to hook it up to the flash sync socket on the lens - presumably setting the tab at X (for X-sync?) - what do V and M mean anyway... So many questions :-) -- // richard <http://www.richardmanphoto.com> _______________________________________________ Leica Users Group.
