Re: [pinhole-discussion] Yet another lensless technique !!
- Original Message - From: George L Smyth glsm...@yahoo.com I like that very much. Now it's a matter of either figuring out the specifics of how to make one and/or waiting for someone to offer them commercially. George, Since I am offering zone plates already, I will add Photon Sieves and Pinhole Sieves to the offering, wait for an announcement on this. Guillermo
Re: [pinhole-discussion] Re: swap
Hello, I love the idea of a swap, and would like to be involved. However I have a huge issue with posting personal information such as a mailing address to a site that can be accessed by anyone on the web. For future swaps I think privacy should be seriously considered. My suggestion is to email out the list only to users who have submitted a profile including mailing and email addresses. This wouldn't be perfect, but it would be better than having this information exposed as it currently is. -William Mokrynski _ MSN 8 helps eliminate e-mail viruses.

[pinhole-discussion] Pinhole Focus
I made two assertions; 1) that at a given extension you will get the same image regardless of pinhole size and 2) that the sharpness was the same for each image. I will stuck to the first and admit I'm on shakier ground on the second. I used TMax 100 4x5 film and shot a scenic, a saguaro cactus at about 25 feet. Examining the negatives and proofs only with a loupe, they appeared to me to be of similar sharpness. Also, I will admit I didn't shoot the whole series of pinholes but only a sampling. I plane to redo the experiment with the whole series to see if I am mistaken. Regardless of the results, doing it is fun and enlightening! --- Ian McKee --- photo...@earthlink.net --- EarthLink: The #1 provider of the Real Internet.

Great stuff Guillermo. It must have been a bugger to poke all those different sized holes in the foil though.

[pinhole-discussion] Re: [pinhole-discussion]
Hello everybody, I really appreciate, all the advice I have recived regarding pinhole polaroids and cyanotypes. Just recently there was a big debate regarding digital photography versus more traditonal techniques. I think that is all well and good. but I bought big dan burkholders book. And it alloed me to make images at a fraction of the cost. I can understand why people would'nt want to sully the purity of the art form. but. buying a load of sheet film is a lot les expensive than buying epson photo quality inkjet paper. Ben

[pinhole-discussion] Dirkon
Hi, I've received lots of emails about the Dirkon paper pinhole camera and so I've added the original instructions for its construction to my web pages www.pinhole.cz in Adobe PDF format. I'd be interested to know if anyone has a go at putting it together. I wish you lots of luck and patience, and look forward to seeing photographs taken with Dirkon!

Catherine - Assuming that the lab made the print on black and white paper, you can very carefully bleach the portions you want to lighten. Water (125 deg F or 52 deg C) - 750.0 ml Potassium Ferricyanide - 50.0 grams Potassium Bromide - 10.0 grams Sodium Carbonate, monohydrated - 20.0 grams Add cold water to make - 1.0 liter I believe that you will need to refix the print following the bleach (and perhaps Spottone any areas that were bleached too far). This is not an easy thing to do. Another thing would be to use Spottone to touch up the negative, though that is much easier than it sounds.

Re: [pinhole-discussion] black dust
If these are black dots on a white background you can pick off the black spot with an exacto knife blade or hypodermic needle. This will leave a pit in the emulsion but that won't be very noticeable under glass. Richard Heather - Original Message - From: Catherine Just blue_medic...@yahoo.com To: pinhole-discussion@p at ???

Re: [pinhole-discussion] black dust
Yes, its hard to tell with out looking at the print, but from my experience the most easy (not always the cheapest) way to spot a picture would be to scan it and retouch it in photoshop. the only problem is finding a scanner big enough for your print. But most larger printing studios have them.

RE: [pinhole-discussion] swap
Traci, From the last swap I sent inkjet printed pinhole photos on premimium glossy paper. I recieved digital, fiber base, RC, and a zerox copy. All were very creative and beautiful prints. If you do random selection, I presume that each person recieving one would send one in return. At least that is what I plan to do. Last year I sent to the whole list which was 49 and recieved 45 prints in return. I felt that it was well worth the effort. (Although I do admit 100% return would have been great, but that's life!) Have a great Holiday and happy printing mailing. I think Zernike Au, in an email did suggest possible home holiday photos as a rough theme. Anything you feel good about would be fine. Take Care, Chuck Flagg
