Re: [pinhole-discussion] paper negative tricks
Hi Mike, A few years ago I made a camera out of an old 8x10 cibachrome developing tank that I had. I sealed the pinhole with a red glass filter and developed the images in the camera. The other cool thing about having a sealed pinhole camera is that you can fill the camera with water before you expose the image to increase the field of view (due to the diffraction of light at the air/water interface) and you can also shoot underwater with it (although I found the results of this to be VERY unpredictable). Give it a try. Cheers, Tim Ever hear of anyone building a developing tank, and adding a pinhole on the dry side of the tube? You would be limited to one film per tank, so you would probably want to build several. Any other potential problems? (I have limited pinhole experience- of the pinhole in the body cap type.) -- Gravity is a harsh mistress The Tick- 1996 Mike Beacom _ Send and receive Hotmail on your mobile device: http://mobile.msn.com
[pinhole-discussion] Film Development
Richard, I have to correct you; 1 roll of 36 mm x 36 is exactly equal to 1 sheet of 8x 10 - 80 square inches. Check Kodak developer tech bulletins. Ian McKee One 8x10 neg has way more surface area than 2 rolls of 135x36. 3 to 4 oz of dilute developer is a bargain. Nobody does 8x10 for the speed. To shoot 12 frames ( my max of holders) is a full days work. Best to develop one at a time. I have tried to do 4 in a 16x20 tube but you can get overlaps.

Re: [pinhole-discussion] my first photo
Good job! What kind of camera are you using, and what kind of focal length? I have always shot film, but would like to experiment with paper. What did you mean by Gimp curves? changing contrast? I have found that this is almost always necessary with my pinhole film scans, and even my digital camera pics. Gimp is a great free photo editor, primarily used in Linux. I wonder if anyone else on the list uses it?

Some snow can still be seen, though it has been 15 degrees centigrade temperatures lately here. Exposure time was 8 mins and negative Kodak Polymax II RC. Developer was diluted Neutol, but still Gimp curves had to be used. Moving to hi-speed film instead of paper has the advantage of shorter exposure times, my son was getting bored during this eight minute shot :-) -matti mjkos...@koti.soon.fi ___ Post to the list as PLAIN TEXT only - no HTML Pinhole-Discussion mailing list Pinhole-Discussion@p at ??? unsubscribe or change your account at http://www.???/discussion/
Re: [pinhole-discussion] paper neg.
I you want clouds and use paper negatives the answer is simple Use a multigrade paper and place a 0 multigrade filter or other colour equivalent behind the pinhole. This will reduce contrast to the point where you get skies and a more continual tonal range. The only drawback is that the exposure time is doubled. The results are excellent Try it Alexis
RE: [pinhole-discussion] BTZS tubes; fixing
or... just fix it for 1/2 the time in the tube then dump it into a fixer tray. TMax, especially, has an indicator built into it (the infamous purple) that indicates incomplete fixing so you want to be careful removing the coloration w/ HCA to pull it out. andy -Original Message- From: pinhole-discussion-admin@p at ???

Subject: [pinhole-discussion] BTZS tubes; fixing One of the big reasons to fix in a tray using the BTZS tubes is to get the fixer to the back of the film so it will remove the pink anti-halation backing during fixing. The only knock on the tubes is that you do tend to have problems with the antihalation dye remaining on the back of the negative. Hypo clear will help get rid of it.

[pinhole-discussion] paper neg.
Paper negatives have different qualities than film and shooting cloudes is definitely not among them. Paper negatives gives me the opportunity to deal with time/light modelling the subjekt. The sun is moving, remember? Exposure-time from 1 - 30 hours makes me think and act differently compared to a 1-second-shot. Paper is not better - it is just different. Alf Christian
Re: [pinhole-discussion] paper negative tricks
I finally got my wooden 4x5 camera lightproof and taken few test shots using paper negatives. Results are fine, but some recent talk here (esp. diluting developer) made me search for methods for better tonality. Flashing (ie. pre-exposure) was one I've already tried, but these tests showed a little increase in details. Diluting the developer is next thing I'm going to try, but still there are other methods, using multigrade filter for example. Problem with paper negative seems to be the total lack of details in the sky, getting the sky with some clouds make the print look more real. Does anybody of you know some web-pages to look for more information? Google search finds tons of pages not necessarily related with the subject. As I scan the paper negatives, there's also the possibilty to use computer to improve the prints, but if the scan shows no details, I'm not going to add some nice clouds from other pictures :-) Most paper is blue sensitive or orthochromatic so both the blue sky and clouds look white. Panchromatic film or paper will help.
[pinhole-discussion] going to use film
thanks all for your information. Building a developing tube seems quite easy and cheap compared to ready tubes. I've taken 6x6 film pinhole photos with my modified Holga and the tonal range is much better than the paper negatives. But now as it looks like I may be able to develop sheet film after getting developing tubes, I'm sure going to use it. After doing some inquiries there's at least one shop here in Tampere that sells Kodak T-max sheet film, so I don't have to order the film from who knows where. The price is though multiple compared to paper negatives. thanks -matti mjkos...@koti.soon.fi
