[pinhole-discussion] stuff i missed - digital and scanners
I owe a debt of gratitude and an apology to Bill, Greg, Guy, John, Gordon, and Andy! I just went back into the archive and found what I had obviously missed with respect to what I was looking for when I asked for help with digital pinholes and scanner pinhole camera setups. It was all there. As I said, I am new and I will get used to this soon. Thank you all for your help Jack
Re: [pinhole-discussion] Lith printing workshops (was: What is Lith Printing?)
Hi Andy, I'll get back to you off-list. Yes it could be done over a weekend. The rest depends on how we structure the workshop, given the type of facilities that you have.

Re: [pinhole-discussion] sheet film instead of photo paper
I've used 4x5,5x7,8x10 without problem. for me the issues were how much could i influence negative contast since I intended to use the negs for contact alternative process prints. Tmax is much the easiest to influence contrast via agitation. don't know anything about xray film.

Re: [pinhole-discussion] sheet film instead of photo paper
I used to work in an X-Ray Darkroom, of course I experimented with the film. There is an example of the results I got at: http://www.chucksphotos.com/Gallery_pinhole.html , it's the one labeled 'Coworkers'. I used an Oatmeal box with a pinhole lens and if I remember correctly about a 20 second exposure. I developed the film in the hospitals processor and contact printed it later.

[pinhole-discussion] scanner pinhole camera?
I am posting this for the second time because I am new here and may be doing it wrong, but here goes... I am thrilled with the discussions that go on here and am delighted with the information. It is inspiring and motivational - both things I need to get going again after having been so long away from the art and craft of the 'hole thing'! I made many pinhole cameras and produced a large body of pinhole images directly onto Cibachrome paper with an old 8x10 portrait camera. I scanned those one-of-a-kind pictures and printed them with an IRIS printer. I also made many Polaroid B&W and color images with a hand made 4x5 camera. I have spent the last many years becoming a fine art digital printmaker and am the one responsible for coining the term 'giclée'. I would love to trade prints and/or digital printmaking information for the tools of your unique pinhole art. If anyone is interested, I am available at: Duganne Ateliers www.duganne.com 2651 Main Street Santa Monica, Ca. 90405 310-314-0050 I have seen listings referring to using a scanner as a pinhole camera. I have looked in the archives for listings relating to this posting and have been unproductive. Anyone remember or know of a way to do that thing? Also, I am still looking for ways of using a digital camera to do pinhole photography if anyone has had the luck of doing so... Thanks, Jack Duganne P.S. Thank you to Meggan Gould and Denise Sallee for their replies and experiences Jack

Any one use b/w sheet film that uses 'conventional' developer instead of paper negatives (other than lith/exotics) ? If so, what kind? Maybe 4 x 5 film packs? Anything larger? Anyone try x-ray film?

Re: [pinhole-discussion] 127 film?
Murray, You bought a filmless classic. The 127 film was discontinued by Kodak in the mid-90s. It took 8 pictures with a negative tha gave a wallet sized contact print it could also take 12 square pictures again the dimensions I do not recall. It fell out of favor due to the 126 film cartridge. James Johnston
Re: [pinhole-discussion] 120-220-620 film? Oatmeal part II
The 120 fiilm is a roll film that is 2 1/4 in wide when used in a Twin Lens Reflex it usually made 12 2 1/4 in pictures on a roll . This film is paperbacked the length of the entire roll. It could also make 16 pictures on a roll. The exact size I do not recall but smaller that 2 1/4 in square. The 620 film is identical to 120 film except I HAD a narrower lip on the spool. The idea been tha smaller cameras could bee produced. It is no longer made. I have some rolls of 620 Verichrome Pan(ASA 125) from the '70s have not used yet. The 220 film is twice as long as 120. This allows 24 pictures on a roll. It has a paper backing at the beginning of the roll and at the end of the roll. I hope this helps! James Johnston

The above configuration usually produces an image that touches the edges of the 4x5 film plane, but never covers it fully.

God I love black foam core.:-) > Even after reading the Pinhole Journal articles and the section in Eric Renner's book about slits, skull density prevented me from visualizing how to make the camera or to make the slits (or where to find the time for experimenting). So, a couple of years ago, I bought a Cardozo camera from Pinhole Resource. It is a beautiful match of design and craftsmanship. The camera has inner spacers that let the slits be arranged in different focal lengths. Black foam core should work great for building a slit camera. Actually, I bought a large piece a week or two ago to make a slit camera that I won't mind leaving in the back seat of the car when its parked outside at night. Tom
Re: [pinhole-discussion] slit cameras?
Hi Guillermo, I crudely measured several of the dozen or so slits that I use. They range from about .5mm to .75mm; most are about .65mm. I wasn't sure how to plug the numbers into the the following formula, since the slits are different lengths from the film plane. Most always the inner slit is 3" or about 75mm from the film plane and the outer slit is 6" or about 150mm. There is only one focal length variable in the formula. Using .65 for both A and B: at 150mm focal length, the result was f 204; at 75mm it was f 102. My guess is that neither is quite right.

Re: [pinhole-discussion] slit cameras?
Hi Brigitte, Further in Jim Moninger's article he mentioned that he saw the banding using .5mm slits and so increased the slit width to 2mm thus making more diffuse images with less banding. I can't see banding in the images that accompany his article. The use or elimination of banding is up to the photographer. Marnie Cardozo's images in the same issue of PJ are much sharper, but include banding. I've dedided to keep the banding in the iconoclast images.
