Hi Aaron,

Well, I have painted the film sheaths and have received my film (NP27 ASA 400) from Wephota in Berlin. I ran a rudimentery film test last week using my 12" Commercial Ektar (which is mounted on a Sinar lensboard). The reason I used this lens was because the cabinet maker still has my origional lensboard in his workshop as a pattern. The good news is, he has made 4 lensboards and is in the process of hand fitting them to the camera as I write this post.

Loading the 12X15" film was quite an experience. The film from Wephota was cut to order, and surprisingly, had no notching to indicate the emulsion side of the film. Using my vast experience as a photographer, I GUESSED which way the film should be loaded, and luckily, was right. Just the handling of these large pieces of film, compared to 8X10" is rather intimidating the first time around.

I exposed the film, making a rather artistic shot of my dining room drenched in the soft light of a grey, overcast German winter sky. 30 seconds at F45. Developed in ABC pyro by inspection and pulled from the soup at 9:45 seconds.

I discovered to minute light leaked in the wooded darkslide, which were easily repaired. Otherwise, all went well. Hopefully I'll have my finished lensboards back in a couple of days, and can then mount my Ross / Dagor f 7.7 480mm and my new Apo Ronar 600mm lenses.

William, the Ukranian company Svema carries 30x40 film, it might fit perfectly. I have been trying to find out more info about cameras in this format (like a russian 30x40) and have come up with nothing. I wonder who uses all these unusual formats in Eastern Europe?

I have only met one other person, a photographer from England, who has this format camera. I believe I mentioned buying film from Wephota (near Magdeburg in Germany) for a very reasonable price of EUR 80,00 for 25 sheets of ASA400 film, cut to order.

I just got back from my cabinet makers shop. He made 4 new lesboards, three of which are blanks, and the fourth has been fitted with the retaining ring from my Apo-Ronar 600mm lens.
Just for information, he charged me EUR 50,00 for the work. All handmade with a beautiful finish.
Here is how they turned out...

an interesting read! keep us updated!

for checking the coverage of your lenses and light leaks in general, you could use a paper negative (must be cheaper and easy to process to see the result)

Actually Nige, I did use the paper neg method to discover the light leaks. And after seeing where they were located on the paper negative, they were actually small hairline cracks in the darkslide.

These were easily located by placing the darkslide on a lit light table in the dark room, and covering the remainder of the light table with black cloth (in the dark of course). After letting my eyes adjust to the darkness, I turned on the light table and immediatly found the culprates.

To make sure the slides wre completely fixed, I decided to completely cover the inside of the slides with a black-out film, which I had used on the windows in my darkroom. A sort of VERY stickly opaque black film, I cut it to coer the entire inside of the slide, but not covering the edges that run in the tracks. This solved the problem and now I can bring the filmholder out into the light without fear of fogging.

I have done that too, and then contact printed it to get a positive. It was a fun experiment.

Sorry for dragging this off topic for just a second, but how do you contact print a paper negative? Wouldn't it be all diffuse if you shine light through it from the back side?


Sorry. Back to the topic at hand...

I'm only guessing as I don't know any theory behind this, but when the two pieces of paper are touching the light has nowhere to difuse. I only contact print pinhole images which are soft to begin with but they look are sharp as the negative

You contact print it just as if you were using a negative, placing the papers with emulsions facing each other. It just takes more light and/or more time.

I thought I heard somewhere too that sometimes they would treat paper negs with an oily substance to make it more translucent. Or is this just a myth?

You could treat the negative with some sort of oily or waxy stuff but you don't necessarily have to.
