LF Studio Flashbulbs last night: Selfish images

Those constructions are excellent. If your artistic friend runs out of dead flashbulbs,you could introduce her to radio valves.
Essentially similar, but amazing levels of internal complexity.

I gave her 6 small ones recently. She prefers small pieces. I let her go through my tiny nuts, bolts and other parts drawers every so often. Some guy wants to use one for a product trademark. I told her get a supply of the consumable product for life as payment. She was not going to ask for anything...

Thanks Peter, I actually have secondary use for used flashbulbs. a close friend uses them in her sculpture. She wants all I produce, Here is her work, but she prefers the interesting shapes of used ones.

How did I miss this post? Your friend has resurrected Gyro Gearloose's helper!

Randy, you very rarely need a meter outside with flash bulbs,either. I used the same Sylvania Press 25's outdoors as well as inside. I used to run around the western San Fernando Valley as my beat for the local rag that I worked for as a teenager. I got the job because I had my own Speed Graphic. Essentuelly, you control the background light with the f stop, and the foreground people illumination with the distance from the lens. Once you get the guide number locked in your head for the film/bulb combination you use, it is very simple.

Jac, you are the flashbulb expert, and have given me much advice. I am slowly wrapping my head around how they work.

I love the fact if I calculate correctly, I don't need to meter. It's Sunny 16 inside now!

Lumenate me. Please!

Good advice. I understand Press photographers always used a flashbulb, inside, outside, daylight and not.

I am old now, but never used flashbulbs or strobe when younger. GN usage took me a while and to complicate matters I have a large quantity of M2 and M3 which are unmarked and mixed up. They differ by 2 stops I believe.

Hey Randy... very cool! I use flashbulbs but never a shield, and never had one "explode" either. I understand the value of the shield, though. Question: is there any significant light loss with that translucent shield?

The translucent shield is more to diffuse the light than reduce it. The loss is probably less than 1/4 stop.
You are bringing back memories. Iused thousands of flashbulbs prior to the invention of the light weight electronic flash. I still prefer them, and rarely use the strobes. I have never had one explode.

Keep in mind that you can use a flash meter with flash bulbs if the meter has a cord. Bulbs come up too slowly to trigger the meter on their own. The cord triggers the meter and bulb.

Bulbs generally take 20 milliseconds to rise; that's what the shutter speed M takes care of - it fires the flash before opening the shutter.

Enjoy!

SOme bulbs have a 20 ms delay, most have a 5 ms delay, and argon filled ones have zero delay.

SOme bulbs have a 20 ms delay, most have a 5 ms delay, and argon filled ones have zero delay.

We have a simple disagreement possibly about the meaning of 'some' and 'most'. All my M synchs delay ~20 ms (M and MF). I have Edison/Mazda bulbs, none the newer small bulbs that might rise at 5ms. The tiny zero-delay bulbs are uncommon and useless to me.

And I have a case of bulbs with a duration of 1.75 seconds, allowing just about any delay wanted, but I can't imagine not using M and a longish exposure. They are great for motion work.

Yes! Is it still going?

Green Sheet??

Long gone, unfortunately. When they decided to become a real newspaper they let the Green Sheet die. What great memories, though. I loved that newspaper. The Daily News still exists, as LA's second largest newspaper.
