Hi Guy, I loved the picture! I'll try coffee developer soon in the future. I understood that the print was developed in coffee isn't it? Was the negative too? Thanks Joao The picture can be seen at: http://www.p at ???/discussion/upload/images/pose_cafe.jpg
[pinhole-discussion] Film question...
I recently came across a roll of Imation 3M IR-HD Recording Film on EBay which being the kind of person I am, I had to haveso now I do.hm I talked to the people at Imation 3M who were very helpful encouraging about using this essentially IR film in normal photography. They referenced using their developer or the Kodak Contact2000 developer which will give great contrast hard dots. I'm planning on using it with either Dektol or HC-110 Dil B for 8x10 pinhole work Any ideas?? Ow yes,I got a roll 13.3 IN X 98 FT so it might be fun... thanks andy schmitt Computerist, Photographer, Slayer of Dragons All opinions expressed are mine...

RE: [pinhole-discussion] Camera Design Problem
is the film plane curved towards or away from the pinhole? is the radius on the 4 or 11 side of the paper? if it's curved away it should be fairly easy to construct removable backs like Max suggested. The only part that may be tricky would be the joint. You might want to put a stop on the dark slide to prevent it from being totally removed. The stop might also be useful to help seal up the slide opening for long exposures. The down side is the dark side flopping around. andy -Original Message- From: pinhole-discussion-admin@p at ???

Subject: [pinhole-discussion] Camera Design Problem Group, I have been making pinhole images on 4x11 inch paper negatives mounted on a film plane with a 5 inch radius of curvature.

Re: [pinhole-discussion] Camera Design Problem
How about a camera with interchangeable curved backs that could be loaded in the darkroom. Maybe to make it easier to build make the back flat where it joins the camera and where the dark slide goes in.

It seemed pretty simple with Coffee, Baking Soda, and Potassium Hydroxide (added to pH 9.0). Being chemically clueless, I thought I'd ask him a few questions. Dr. Williams said: ... We used real potassium hydroxide. As it turns out, you would have to use the old formulation of Drano, one where the active ingredient is sodium or potassium hydroxide. The new formulation does not contain this active ingredient in useful amounts On another note, we later found that mint leave extract - boiled extract from one store package of fresh mint leaves - works better than coffee and can be activated by just using sodium bicarbonate (again about a tablespoon full per liter) - much safer. I did learn later that Potassium Hydroxide is also known as Caustic Potash (Chemical compound with formula KOH. Pure potassium hydroxide forms white, deliquescent crystals. For commercial and laboratory use it is usually in the form of white pellets. A strong base, it dissolves readily in water, giving off much heat and forming a strongly alkaline, caustic solution. It is commonly called caustic potash. It closely resembles sodium hydroxide in its chemical properties and has similar uses.) Genuine Potassium Hydroxide is available from www.bostick-sullivan.com, but if anyone comes up with any substitutions for Potassium Hydroxide, let me know (as I am still chemically clueless).

Re: [pinhole-discussion] Coffee developer - Picture uploaded
John, I would think that the missing ingrdient might be the potassium hydroxide , which according to The Darkroom Cookbook is supposed to act as a developer accelerator. The print I've posted comes from my single experiment with coffee developer. I really should get back to it. Michael Georgoff was saying in a separate posting that he was going to get some from Bostick Sullivan at http://www.bostick-sullivan.com/ I've bought from them and they are very good people. According to my catalogue, the stuff is caustic potash and sells for $17.50 for 500gm from them (plus shipping) (not exactly cheap!). I suspect that 500mg will take you quite some distance with your coffee. The recipe calls for only 6 rounded teaspoons of the stuff per liter of coffee. Best, Guy - Original Message - From: John Yeo jonn...@thegrid.net I tried developing a print in coffee once. It didn't work at all. I mixed up instant coffee at twice the reccomended dilution, printed a picture and put it in. I didnt' use baking soda, I just assumed it was used to make the soup less acidic. I didn't monitor the pH because it said the best pH was 9. I figured anything would work, but not be the best. It did not work at all. I didn't do any exposure compensation, used ilford multigrade RC paper. and left it in the coffee for over an hour. Any suggestions to what could have gone wrong?

Guy, Considering I enjoy coffee almost as much as pinhole photography, I don't see any conflicts.
