Now, the old Braun flash I remember fondly is the RL-515.Â This was the flash I learned to do bounce flash with (at the behest of the editor of Carleton’s Alumni Magazine, for whom I was the primary photographer at the timeâ€”Jane Kellogg maybe?).
Powerful enough to bounce the flash off the ceiling in most institutional rooms and expose Plus-X (ASA 125)Â at f/5.6. Recycled in 1-2 seconds to full power.Â Being able to shoot the slower Plus-X rather than the grainierÂ Tri-X, and being able to bounce (producing softer and more suitably located lighting) really set my pictures apart from others in the early 1970s.
Fully manual, of course; it had two power settings, and two reflector positions (normal and wide), but after that you were on your own.Â To bounce, you estimated the distance the flash traveled, figured the aperture for that, then added some more exposure (generally 1-2 stops) to account for the reflectivity of the bounce surface and the diffusion of the beam. Then you made up for any miscalculations in the darkroom.
It was a monsterâ€”square flash head about 3Ã—3 inches, an L-bracket to attach it to the base of the camera, and a separate battery pack that hung over your shoulder. Note it’s set up to go on the right side of the camera; in those days the right hand was the support hand, with the adjustments (aperture, focus, zoom if you had it) being done with the left hand.Â The hand positions are the same today, but with the conveniently-located control buttons and wheels, the right hand also controls exposure and AF trigger and things.Â (Not everybody does things the same way, either than or now.)
I owned two of them at various times (the first perishing in a friend’s car fire!).
What that pack contained was a weird historical relic: a 510V primary dry-cell battery.Â (Eveready 496, NEDA Listing 741)! Even in the mid 1970s they were expensive, I remember paying $35 (which was about what four 100-foot rolls of Plus-X cost, about 75 rolls of film). But that was the only flash I ever had with that speed of recycling, and I don’t think I’ve ever had a more powerful one either.
I wouldn’t wonder if the 510V rechargeable packs for various flashes derived from this and thus were electrically compatible with it. I don’t think there’s much chance of finding any of the actual dry-cell batteries at this late date!Â (Huh; I do find a place claiming to have them for saleâ€”for $200; electronicplus.com)
My Sunpak 555 with Quantum Battery 2 was a better flash than this, because of the ability to work with OTF flash exposure control in modern cameras (I used it with Olympus OM-4Ts and many different Nikons). None of the others I owned even came close, especially the Honeywall Auto-Strobonar 892s.
