Not a lot of UV or blue light in tungsten. You'd be better with some blue LEDs and save a lot of energy too.

I have used one J.Lane glass plates. The most interesting aspect is working out how to dry them: you cannot just hang them like your other large format sheets. Some cheap, commercially available...
Wrong Vaughn. But yeah, phone selfies have changed what is acceptable for portraiture.

Wista 45 metal field cameras.
The flat metal frame has a couple of raised bumps. Generally all the bellows, backs and lens boards are interchangeable between cameras; the older frames and rails are not interchangeable with newer...
I have both the Toyo 4x5 metal and plastic framed bellows, and replaced both with those from eTone. The metal frames need the smaller size bellows, the plastic the larger size.
The “S” is for "Seemed like a good idea at the time." これはアメリカ人を混乱させるだろう
Forget it and buy a replacement, the pinholes will keep returning. I purchased a new-old-stock still-in-box Toyo 45 bellows and every corner leaked light. The Toyo synthetic bag bellows also leak...
What do you want to know? The published marketing literature has errors and does not really document when specofic chamges were made. The web site (I forget the name right now, jyst search for...
Yes you're right.
What makes you say that? I bought a 5x7 tank a couple of years ago, a few days after it arrived I tried to order another for 4x5 and am still waiting.
The tank is good, similar to the Nikor...
The question is equivalent to "should I get a 20mm lens or a 28mm lens?" The only honest answer is "Both, of course."
If you can only get one then a deciding factor may be which angle of view you...
Of the single-coated lenses, those in size 0 shutters (150mm and shorter) are always Seiko. Lenses in size 1 shutters are often found in either Seiko or Copal. The front and rear cell thread diameter...
There are two versions of the lens, one in a Seiko shutter the other in a Copal. In my testing the Copal shutter version has a slightly larger circle.

A downside to continuous agitation is the inability to take advantage of localised compensating effects produced as developer is exhausted and restrainer is produced at edges. Another may be...
Many, many new-to-large-format YouTubers do this. That, and shoot wide open with extreme tilt to get whacky planes of focus because bokeh.
JOBO solved the problem a decade ago with the 2520 tank and 2509N reels. Not cheap but works well for 6 sheets
It would have been designed for 8x10. I believe Toyo updated the M810 with longer bellos extension specifically or the 1200mm version.
The Fujinar 250mm (or 25cm) f4.5 lens covers about 286mm. In huge Shanel 5 shutter, or barrel. IN the Shanel 5 shutter they appear to be common on Rittreck View 5x7 cameras (the shutter was made by...
The challenge is that for a 4x10 camera it's the 10 inch dimension that needs to be accommodated. You really need to start with an 8x10 camera.
If you choose a telephoto lens, note that the design severely limits tilts and swings. The long lens barrel and optical design cause mechanical vignetting when the lens is rotated around the shutter...
The Fujinon T 600mm won't cover 8x10, it just covers whole plate 6½x8½ and 5x7 with some movement, but note that tilt and swing are difficult with telephoto lens designs.
Differentiate between a...

They probably mean an infrared light source, or an extremely deep, barely-visible red. More likely it's a translation error.
Some panchromatic film data sheets allow for use under a deep green...
It's good that car makers do that, otherwise there would be half the number of lanes at the gas station to fill up on. Fun fact: the little picture of the gas pump on the dash indicates the side of...
A dry cabinet would be ideal but air-tight food storage boxes, a humidity indicator strip, and a couple of bags of desiccant also get the job done and scale well. If storing in the camera bag I keep...
That lens has an image circle 141mm, will not cover 4x5 (152mm) at infinity.
That's probably dichroic fog which can look like image reversal. Probably exhausted fixer, or used fix with dissolved metallic silver that's precipitating out (causing the dichroic fog). Try...
ALL colour commercial work was photographed in reversal (slide) film. That's what the printing industry required. The only pro photographers that used colour negative film were wedding and portrait,...
The wd40 washed off the protective layer of oil. Next tine clean with wd40 then wipe with light machine oil.
The thing to understand about rust is that the iron-oxide molecule is larger than the metallic iron so it breaks the crystal lattice and becomes mechanically weak, which exposes fresh iron underneath...
Unexposed developed reversal film will be Dmax black.
I use a JOBO 2552 tank (actually a Chinese copy made by Poilot) and a Poilot reel, which is similar to reels made by Catlabs and others. The reel holds six sheets, can be fiddly to load (they all...
I've bought a Rittreck View that had Dymo tape with "STUDIO 2" written on it. I've also read that they were favoured by commercial street portrait photographers around tourist spots in Japan.
Note...
Hmmmph. REAL photographers do it in water from Homebush Bay.
(The suburb of Rhodes, adjacent to Homebush Bay, was an industrial area that included many chemical factories like Union Carbide, where...
A lot depends on the amount of movement you require, and how wide you want. Before you get too carried away with wide, consider whether your camera bellows will compress and if it does, whether the...
Given the lens isn't in the correct shutter I'd recommend returning for a refund and getting one that is in the right shutter and mounted on the right lens board. Futzing around getting apertures...
Before buying the lens, get in touch with a repair person familiar with Copal 1 shutters and get an estimate for a CLA.
Why not use UV LEDs? They generate a lot less heat, use a lot less energy. Probably cheaper too.
Thanks Mark, I will henceforth refer to cos^N falloff. :)
