My UL 20 x 59 inch camera build in progress

Hi all,

unusual circumstances have propelled me into building a rather large format camera film size 50 cm by 150 cm, (almost 20 by 59 inches). The building has already taken 2nd stage and progressed substantially, more can be found on my web here http://cargocollective.com/martinzaugg/ultra-large-format-camera

Please feel free and give your feed back, both good and bad.

Cheers all

Wow Dr Croubie, that was a quick reply.

I kept the mold for the bellows in case of mishap with the finished one. I hope don't have to do another one.
The lens was custom made by a professor at a local (Taiwan) university. I am the builder of the camera, and my mate is the photographer, who approached someone, who approached someone else, who approached me to build it. We managed to get a Taiwan Government Artist Foundation funding for part of the cost. So the project got from building something to "but seriously now". Our aim is to test shoot within 2 months.

Cheers

Here what it looks like after first time assembly for lens test. Little monster I must admit, yet still (trans)portable, so of sorts.

Hi momus

it is the way I have build most successful projects. In my teen years, I had my own B/W darkroom ( and subsequent Ciba Chrome) and I liked to do bigger posters. So I am not quite a novice to the subject in general, but I never build a camera.

Use of the camera will be my mate who "commissioned" it and once finished I will then take 2nd place and follow him on his first outings.

Many problems still to solve: Initially we intend to produce our own film (thin paper) with light sensitive chemicals for the negative, then contact/expose (excuse if I not use the right term) this developed neg on yet another rough texture handmade and coated paper. The result should resemble a Chinese Landscape print, hence the size. Google " Lang Ching-shan " and you get the idea.

We will see, I keep you all posted. I will same time update my web site to keep information on the go.

Cheers
Martin

 

Thanks! I will tell my mate to check it out.

 

Lens spec.: 1000 mm, f 14-64 (?), 100° view angle
It is a custom made lens my mate happen to know someone was producing. You can see the camera full build and re-build (yes, I am doing it for the second time) in the link pasted in the first post.

As to film.....really a headache, so was most anything else, just tackle one problem as it comes along, if no solution, let it go and move on to the next. Pretty much what you may see when you read my web page.

There is already very good advice coming along as for film, and I am sure more more good advice on future topics will come along, that is precisely why I post here, and to share my experience with you. Thank you all.

Cheers

WOW! Spooled film in that size....if something suitable turns up, then you are spot on: I would not mind to doing a new camera body. Because I will need to make about 4 to 5 new current film holder (double sided) anyway once all tests are good.

BTW, we had a bit of a problem with the red LED lights in the dark room, it would expose paper. We may have solved it by reducing the numbers of lights and keep them at a distance from the exposed paper. If anyone had similar experience or a good tip, I like to hear. I first believed the LED lights may have the wrong wavelength or something.

So nice to read all this, it stops the guessing game in its tracks. Old school dark room lights were just red 40 w glow lights and always worked.

An up-date on the camera, actually the size is 20 x 60 inch format, got confused with the inches.
Now just done some paint finishing touches, following a few pics:


Camera parts ready for sanding


Spray painting w/o the usual dress up


The frame, focus train assembly


Looking all right, ready to take the box


The box is hold in place by 4 8mm toggle screws


A side view, you may spot the toggle screws


As seen from the back


Lens frame on the focus train


The viewing screen, 3 pieces of 5mm glass to avoid breakage


Double sided film holder in place

Because of limits of pics posting per reply, I have to stop here. I will follow up shortly.

You got that right, not an ordinary cabinet makers workshop. I am building this on the premises of an artist community, http://dctaiwan.blogspot.tw/ inside a new Building that will be decked out with all sort of art, and our darkroom is on the 14 floor. This is all kind of a special arrangement. The project was sparked by a young photographer living nearby, contacting us here.....the rest is history. We got 2 grants to help build it. But the custom made lens took the biggest chunk from that.
As to trailer, I don't know what you mean. Most parts will snugly fit into the box and can be carried by 2 people. What we need is a VW bus or similar to carry it all. In the begining we can borrow such a car from the community. I shall post more pictures as it progresses, and yes, I can hardly wait for the first picture. But the darkroom set up is next.

Might as well post the remaining 4 pics:

Focus wheel


Toggle screws detail, securing the film holder.


Film holder as seen from inside, the light color wood will all be blackened .


2 simple brackets and all is rock solid.
