While the 'T' setting seems common on cameras that provide shutter priority I'm not so sure about the 'B' setting - can anyone confirm/deny this?-- Hooperbloob 01:50, 1 May 2006 (UTC)
I reverted my possibly mistaken historical interpretation, after finding two books supporting the other (pneumatic bulb) interpretation. Apparently the flash bulb was invented in 1929, and the B setting was common on cameras long before that. Dicklyon 18:14, 1 May 2006 (UTC)
It would be useful to have links to photos demonstrating the technique. Lee M 01:03, 3 February 2007 (UTC)

With the rubber bulb, you could make exposures of about 1/5 sec. and with a dark slide in front of the lens too if you give it a swish. In portrait photography, it made a more satisfying sound. The pneumatic shutters made a hiss with the escape of air. Bulb was for any speed you could manage. T was when the exposures were longer - minutes or hours. Rubber bulbs are still sold: Kaiser does one with yards and yards of tubing. There is a hemispherical one you put on the floor and step on. They let you walk around and interact with your subject or have someone else do so. RPSM 15:44, 13 November 2007 (UTC)
"By early 1898, Mattie's interest in photography expanded; she purchased a 4"x5" plate camera that offered ground glass focusing, and a multispeed shutter thereby allowing her to keep a more detailed photographic journal of her new life. Curiously, Mattie appears in many of her own photographs. She made this possible by using a long piece of rubber tubing which was attached to her camera's pneumatic shutter at one end with a rubber bulb at the other. Squeezing or stepping on the bulb released the shutter and made an exposure." http://www.vpl.ca/branches/LibrarySquare/spe/gunterman/biography.html (Vancouver Public Library) RPSM 15:52, 13 November 2007 (UTC)
I have used a camera with a rubber bulb without a pneumatic shutter. It was in The Camera Club in London in about 1968. They had a dangerous looking flash that crackled and sparked, and you were supposed to use open flash (no article yet) keeping the room lighting low; pressing the rubber bulb then the flash switch and then releasing the bulb. I have also seen a collection of mahogany cameras for sale, one of them fitted with a shutter of rubber I think like two eyelids in some material with concertina box pleats.
Previous to a rubber bulb or shutter, there were cameras without shutters using the lens cap. You take of the lens cap, wait a moment for the camera to stabilize while shielding the lens. Remove the lens cap. Count seconds and then replace.
Withdrawing the dark slide completely it can also be used as a shutter, and then it is possible to achieve 1/4 of a second or so. Normal expose for portraits with tungsten lighting is around 1/8 second in any case. —Preceding unsigned comment added by RPSM ( talk • contribs) 14:01, 14 November 2007 (UTC)
The M and T information in this article may be original research and may be specific to a particular manufacturer. Some references would clear this up though. The article should first be neutral to any manufacturer though some examples would be fine as long as it's clear that they are specific to a manufacturer.-- RadioFan ( talk) 03:38, 30 May 2009 (UTC)
In order to help out with one of the "citation needed" tags, I just added a citation in regard to the existance of a BULB setting in shutter priority mode on some cameras, notably the Minolta Maxxum 9000, Maxxum 7000, Maxxum 8000i, Maxxum 7000i. I am not aware of any other cameras supporting BULB in S-mode, certainly no Minoltas, but I would be interested to learn about them, if they exist. It remains unclear to me why Minolta might have implemented it this way in these cameras, when at the same time they warned about using BULB in S-mode in their user manuals and suggested to use M-mode instead. After all, these are fully electronic cameras, so this cannot be down to some mechanical constraints. Also, these cameras are quite different internally, so it cannot be a design oversight or bug, either, in particular since the low-end models did support BULB in M-mode only. Minolta must have designed it this way on purpose, but why? Any ideas? -- 84.63.26.178 ( talk) 01:43, 13 October 2009 (UTC)
Should the section on digital photography perhaps be last, rather than first? History and uses seem more general, and thus applicable to all cameras, and perhaps should be first? 69.115.19.58 ( talk) 01:42, 24 June 2009 (UTC)
