Zeiss Ikonta Shutter - Rapid and Synchro - both have flash?
"Ken Hart" wrote in message ... "Nicholas O. Lindan" wrote in message ... "Ken Hart" Snipping here.... Back in my college days, (Pennsylvania Governor's School for the Arts at Bucknell University), we used to sneak into a dorm room, remove the light bulb from the ceiling fixture and screw in a flashbulb (#5?). Then we waited for the occupant to return. 110V was plenty of voltage to fire those things! Maybe either a General Electric No.50 or Wabash-Sylvania No.3. These were about the size of a No.2 photoflood and were meant to fit into standard studio reflectors. These lamps are listed as having six million peak lumens. The open flash guide number for ISO-100 film is around 780. These were the most powerful bulbs made. If more light was needed you had to use flash powder. The GE No.5 or Wabash/Sylvania Press-25 was a bayonet base bulb, very common for both press and small amateur cameras. -- --- Richard Knoppow Los Angeles, CA, USA |

I have the flu from hell despite getting flu shots not long ago. I sure wish someone would come up with a real cure for this. I agree with that wish! My wife came home with a "cold" in late January. My "cold" started on 7 Feb, a week later it became a "flu" with fever, a week after that i developed a sinus infection, all despite my having received a flu shot in November. Penicillin killed the sinus problem. I am in week four, and still have some symptoms. We live in Victoria, BC. This particular virus strain is a really nasty one, and widespread from the sounds of it. I know this is off topic, but i wanted to wish Richard K. a good recovery. I don't have large format camera, but a 20 year old Pentax 6x7 instead. Just had the foam light trap gaskets replaced last summer so that i can go out and take more shots without danger of getting the sticky old foam bits on the film pressure plate. Typical cost for such a job is CDN100. -- Regards / JCH |

Whatever is going round now is nasty and seems to take forever to heal. I thought I was getting over this but it began to get worse again a couple of days ago. No fever, mostly lots of congestion and a bad cough, slight sore throat (new symptom). This doesn't have the symptoms of a bacterial infection. Both colds and flu are viruses so anti-biotics won't do a thing for them. -- --- Richard Knoppow Los Angeles, CA, USA |

My GP gave me the anti-biotic to act as a preemptive measure in case the weakened immune system gave pneumonia or sinusitis a chance to develop. Some people up here actually did develop a pneumonia after this "cold/flu" combo virus. I don't know if the pneumonia was the viral or bacterial variety. -- Regards / JCH |

Could you name three brands and formats i should look into? Back in 1982/3 i rented a 4x5 camera once to complete an assignment for a glossy magazine spread. I used Ektachrome sheet film if i recall correctly. I can recommend one: get a nice used Crown Graphic (*not* a Speed Graphic), with the Kodak Ektar 127mm lens (one of the most common). Yes, it lacks movements (tilts, swings, etc.), but it'll get you started very nicely, and folds up into a nice compact package. My Durst enlarger can handle a maximum negative/positive size of 6cm x 9cm. I would need to get another enlarger. My darkroom (still to be rebuilt) is _very_ small. Like LF cameras, used enlargers are now going very cheaply, either locally available or on a certain little web auction site. (If you're in an area served by Craigslist, check there.) A 4x5 enlarger doesn't take up that much more room than your present one. |

I have _never_ looked at MF or LF enlargers. Are they mainly condenser types, or the diffusion types? For example, the condenser in the Durst is already pretty massive and heavy. I shall also have to design the enlarger base surface for multiple enlarger mounts. -- Regards / JCH |

I shall also have to design the enlarger base surface for multiple enlarger mounts. -- Regards / JCH The usual reason for rejecting the Speed Graphic is weight, the Crown is lighter and has a shallower box. However I do find the focal plane shutter to be useful especially for barrel type lenses. Also, Crown Graphics, originally the economy model, are often more expensive than the Speed Graphic on the used market. Either will give you a taste for LF although they have very limited movements and limited bellows draw. Graphic cameras were intended to be hand held and offer a way of getting a large negative for situations where a tripod can not be used. Older Graphics do not have some features of the later series but these may not be important to you. The Pacemaker Graphic has a front tilt which is not available in the earlier models and a body release. I would choose a camera on the basis of condition rather than model. Graphics made after about 1951 had the Graflok back as standard. However, the back could be refitted onto any Graphic so many earlier Graphics, including the Anniversary series, are found with the Graflok. This back is desirable because it allows using certain accessories like roll film adaptors but has no particular advantage for shooting sheet film in conventional holders. Make sure any Graflok back has the Ektalite field lens (Fresnel lens) installed. Some very early versions did not have the lens but later ones all did. The problem is that they are sometimes missing and replacements are hard to find. The presense of the lens is important in establishing the correct plane for the ground glass, that is, if the Fresnel is missing the ground glass will be in the wrong position. As for lenses, the best of the standard lenses were the Kodak Ektar f/4.7, 127mm and f/4.5 152mm (not often found). Next best are probably the Zeiss Tessars found on older models. I have not had good results from the Wollensak Optar series standard lenses although the telephoto lenses are very good. Unfortunately, Graflex went to the Wollensak lens as standard in the early 1950's. The Wollensak shutter was better suited for use with a flash synchronizing solenoid than the Kodak Supermatic and that may have been one reason. Both the Wollensak and Kodak shutters are excellent but many of the Wollensak lenses leave something to be desired. The Kodak Ektar can IMO hold its own against modern glass. There is a great deal more on these cameras at the Graflex org site at Http://www.graflex.org -- --- Richard Knoppow Los Angeles, CA, USA |

I shall also have to design the enlarger base surface for multiple enlarger mounts. The usual: Omega (D2), Beseler, etc. Shoot: I just saw a Beseler 4x5 enlarger, at the Oakland Museum White Elephant sale, going for about $25 (no lens, but otherwise looked complete). These are all condenser types. In the event that you need parts (which is likely, since many enlargers will come without needed parts, like negative carriers, lensboards, etc.), you can find these on that small little on-line auction site. Likewise, lenses (including really good ones, like Componons, Nikkors and Rodenstocks) are going for cheap. Hint: get the next-size-up lens for your format if you don't need to make big enlargements; for instance, get a 165 mm instead of a 135 mm lens for 4x5. This will give you better corner-to-corner sharpness. Older enlargers, like the Elwoods (mostly found in 5x7 size like mine) are diffusion types. The baseboards are a little larger than your Durst, but not by much. |

Crown vs. Speed Graphics [was Zeiss Ikonta Shutter - Rapid andSynchro - both have flash?]
On 3/2/2008 3:35 PM Richard Knoppow spake thus:
The usual reason for rejecting the Speed Graphic is weight, the Crown is lighter and has a shallower box. However I do find the focal plane shutter to be useful especially for barrel type lenses. Also, Crown Graphics, originally the economy model, are often more expensive than the Speed Graphic on the used market. Either will give you a taste for LF although they have very limited movements and limited bellows draw. Graphic cameras were intended to be hand held and offer a way of getting a large negative for situations where a tripod can not be used. (Like that famous picture of Jack Ruby shooting Oswald, where at least one handheld Graflex is visible.) Since we're on the subject, yes, I should have mentioned about the barrel lenses, though these are more rare than lenses with shutters. Questions: 1. I didn't know that Crowns go for more than Speeds. Is this because people like the former better, or for other reasons (see question #2)? 2. Do Speed Graphics typically have working focal-plane shutters? I would have thought that because of the complexity of this mechanism, it might be likely to fail in cameras of this age. (I've never even seen a Speed Graphic up close and personal.) |
