[pinhole-discussion] Re: digital pinhole cameras
why not experiment with one of the cheaper toy digital cameras? there are several available, including a barbie camera. then if it seems worth pursuing, move on to bigger and better options. there was some discussion earlier of adapting a flatbet scanner for this use... >I know there has been some discussion of digital >pinhole cameras on the list, but not much... http://www.lsvarch.com/deadletter"; target=_blank>http://www.lsvarch.com/deadletter/gfx/logo.gif";>

Re: [pinhole-discussion] New image "saloon" uploaded on behalf of Pete Eckert
You are correct. I have only been totally blind for a few years. I still dream in full vision. I've been learning how to take pictures for about a year. I was a sculptor. I lost my vision slowly. I adapted and got an MBA. Four years ago I left my job as a business consultant. I spent a while considering what to do next. First I was a martial arts instructor. Martial arts have been one of my methods of adaptation. That job made me realize that the senses could be pushed much further than I assumed. Now I am returning to art to apply what I learned from the last job. Vision takes up an enormous amount of nerve bundles in the brain. It is possible to rewire all of that to be of use to the other senses, as long as you have a understanding of the data coming in. Like a baby learning to see, sight is meaningless until the mind can grasp the information. I am working on learning how to translate the other senses to a minds eye view. enough background info, on to responding to your post. I would still have some interest in light if I was blind from birth: like a astronomer viewing objects in space using radio waves. I use sighted folks descriptions of my finished photos to confirm or disprove what I envisioned in my minds eye. The process of taking photos is an event for me not a product. Once the product has been manufactured I involve sighted people in the art process. Their descriptions of my finished photos help me sharpen my senses to go out and apply what I have learned. I avoid asking for any help in taking the actual picture because that would alter the photos by making them from a sighted perspective. I have learned to question my own assumptions and those of others. I focus on exploring the range of my senses. this makes what I am up to more conceptual art rather than photography. While trying to teach sighted fighters to spar blind folded I learned that sight masks the other senses. It is as if there is only a set amount of attention available. When sight is removed the other senses don't become stronger. The brain just has that area once used by sight available. actively attempting to rewire that area results in a better ability to translate the other senses to minds eye sight. I suspect the areas in my brain once used by sight would still show up as active if studied with medical devices: (as if sight was stimulated in a dream.

Hey you allyeah, Polaroid still markets this tank, I've seen 'em in Calumet catalogs. I can't help you on the other company, but I have made my own "poorman's clearing tank", out of an old Yankee sheet film rack (from a busted daylight tank) and a rubbermaid storage container...the rack is one of those multiple sized ones that holds up to 12 sheets from 2.25 to 4 inch widths...I use it for both 665 and 55 negs. The container holds a gallon or so of liquid, I just fill it up to cover the little sheet rackI mostly use water in the bucket, and just keep the negs in there until I get back to my darkroom, and then I treat them in a mix of Permawash, or I'll do the sodium sulfite sometimes...I have been able to clear the negs in hypo clear, permawash or even water... The Yankee tank is one of those older b&w plastic film developing tanksif you look at a picture of the polaroid bucket, the rack that it has, looks suspiciously close to the yankee onethat Yankee tank is pretty miserable for actual film developing, so you can find them dirt cheap in used camera stores... p.s., I've used plastic zip-lock sandwich bags, or styrofoam cups in the past as welljust as long as you keep the neg submerged & don't disturb it too much, you'll be okay... hope this helps, KT Opinions expressed in this message may not represent the policy of my agency.

Actually, pinhole is about the only type of photography I spend time on anymore. I love not knowing what the results are going to be (usually something interesting). The mystery and suprise, suspense even, is great. I'm just looking for a way to make it more convenient. And I do enjoy "thumbing my nose" at technology, but mainly at high tech camera/lens technology, not necessarily technology in general.

In our family, my wife works with ZonePlate exclusively (when she works lensless). She finds that it has a lot of similarities with what she does with Infrared photography. I work almost exclusively with pinhole. If you are into 4x5 photography, you might want to look into the Zero 4x5 which has a turret that provides for both pinhole and zoneplate imaging. It's easy to shift mode as you change the film holder for a new image. If there was a similar turret in the Zero 2000 or the Zero 6x9, you'd have to wait until the end of the film to change mode. The other advantage of working 4x5 is that you can do contact prints of the negative and get some very nice images without having to use an enlarger. Cheers, Guy

[pinhole-discussion] digital pinhole cameras
I think most pinholer's use pinhole cameras for the romantic / nostalgia reasons- kind of a way of getting back to basics, and thumbing one's photographic nose at "technology". Hey, why not forget pinhole, and just take your digital camera picture, and apply some kind of "pinhole filter" to your file in Photoshop? Seems much easier method of achieving the end, than retrofitting some kind of digital back to a slow pinhole camera. I would be willing to bet you are probably not into pinhole for the nostalgia reasons listed above, so it might be best to bag the pinhole altogether... > >I know there has been some discussion of digital > >pinhole cameras on the list, but not much...

As ithink about your image, i have a question which I think pertains to our art and is not just ersonal poking around.

[pinhole-discussion] Re: [pinhole-discussion]My apology
Guillermo, Thanks for your explanation. I am a bit embarrassed since I have been calling that photo a pin hole shot instead of a zone plate one. My apology to all. The camera I usually use is a Mamiya with a body cap pin hole I made. A friend at a local camera store showed me her new Zero 2000 she had bought on line. I was so impressed with it she let me try it out. I guess I should have asked more about the zone plate at that time. The camera is exquisite. It got a lot of compliments while I was shooting in San Francisco. The manufacturer has my compliments. Pete
Re: [pinhole-discussion] digital pinhole cameras
First off, the "pinhole" video cameras are actually lens cameras with a pinhole in front of the lens to male it more concealable. Second, NO video camera is capable of producing nice looking digital prints at 8x10 ot 11x14. The resolution just isn't there. To make matters worse, "pinhole" security cameras are usually low resolution even for video. A 4x5 digital back is a VERY expensive option. But how about a polaroid back? If you're going to scan the image and make digital prints you can avoid the hassles of storing and clearing the negatives (see the ongoing discussion in the list...) and have a choice of color and b&w films in a wide range of film speeds (100 to 3000). Mike Vande Bunt Bretton wrote: Hi, I know there has been some discussion of digital pinhole cameras on the list, but not much...
