    Flashbulbs were/are often used in large reflectors. And they put out a deliciously large amount of light.

    Electronic flashes are often designed to be as small as possible. That means smaller amounts of light pumped into smallish reflectors.

    The size and the shape of the reflectors and the quantity of light emitted by the source makes a big difference on how the photos appear.

    As far as I know, Congress has not passed any laws prohibiting the use of flashbulbs. I have two or three thousand squirreled away. A few years ago, on eBay there was a guy selling cases of Press 40 bulbs and I got seven cases of 120 bulbs for fairly cheap. There are still lots of M-2 and M-3 bulbs available. Press 25's and #5's are common but run about $1 per bulb. If you want something specialized, like the bigger focal plane bulbs or infrared bulbs, they can be quite expensive.

    I am confused again. I've had a reply from an APUGer( Henry Finley) telling me why you can't electronic flash with Speeds other than on the B setting and yet you have managed it.

    Were there Speeds that were usable with electronic flash. There must be a difference between what Henry Finley is referring to and what you are referring to.

    Is there a simple explanation that reconciles what seem to be irreconcilable statements? The only one I can think of is that you did it on the B setting but this would seem to pose great if not impossible difficulties unless the scene was pitch black and the only illumination was the flash so opening to B and shutting it again resulted in no other light reaching the film

    Thanks

    Interesting, I didn't know the Speed Graphic didn't have an equivalent to the 35mm world's SLR flash sync speed, like 60, where the first curtain opens, syncs and then second curtain closes...

    Lens shutters would solve that problem, certainly.

    I sometimes use flash bulbs with 4x5 rangefinder, because I am shooting a Grafmatic with 6 shots. Maybe I am prepared to shoot 24 shots max if I am ambitious, for any one excursion.

    A small flashgun with a handful of bulbs is reasonably lightweight and fairly convenient for the purpose. I'm not taking that many pictures, so the fact that I only have a few total flashes is not as significant when shooting 4x5.

    There are flashbulbs available which are more powerful than electronic flash, also. (in case you need extreme amounts of light).
    The most powerful handheld electronic flash does not produce as much light as the tiniest "Peanut" bulbs.

    Graflex used a moving slit curtain. The slit was fixed sizes. It is one moving curtain, not two independent curtains.

    Lens shutter solves the problem only if that shutter supports X-synch. Many, if not most, do but there were some shutters that did not have synch except that improvised using a solenoid... and that can't fake a X-synch.

    EDIT: what Serius refers to as "O" setting on the Graflex focal plane shutter is FULLY OPEN - meaning the opening is 4 inches on a 4x5 camera. That is not a shutter speed setting, per se, but a way to keep the focal plan shutter curtain out of the way when using a lens shutter.

    Flash bulbs meant for focal plane shutters had a longer burn time to accommodate the moving slit. Electronic flash cannot do this, AFAIK. I think the bulbs were labeled FP or something similar.

    If I remember correctly, FP bulbs were bayonet-base, gas filled fast peak bulbs designed to be used with X sync at faster shutter speeds. Regular flash bulbs didn't work well at high shutter speeds because you only got to use a small part of the burn (and thus got a low guide number).

    There were long peak bulbs designed for focal plane shutters; I think they were all screw-base.

    I understand FP to stand for focal plane. However, regarding X-sync- I have several cameras with separate sockets for X sync and FP sync.
    So it would appear they were not designed for X sync.

    Sunpak makes, or made, the 120J flash, a bare bulb with large parabolic reflector, to emulate bulb-type flashes. Anyone I've talked to who has used one has loved the quality of the light from it, compared to regular strobes. Prices on used units have remained strong.

    Some other companies made similar units.
