[pinhole-discussion] PINHOLE LIGHT REFLECTIONS

2002-03-26 Thread Jeremy Siemens
Hi Philippe, Painting the inside of your camera black (or using black paper) will definitely reduce the amount of scattered light in your camera. You could avoid scattered light reflecting off the inside of your pinhole by using a non-reflective material. I've heard of people using silver shim

I just want to say thank-you to all the people on this list who freely share their experience and knowledge of pinhole photography. Although I do not frequently post questions, I am always impressed by how other people's questions receive immediate and thorough answers. A few days ago I used our

[pinhole-discussion] alternative darkroom chemistry

2001-12-20 Thread Jeremy Siemens
Hi everyone, While we're still talking about darkroom chemistry... just wondering if anyone has tried using vinegar as a stop bath in the darkroom. Obviously there would be no colour change when the pH gets too high, but I don't process large volumes of prints at any given time so I can't see

[pinhole-discussion] Re: enlarging paper negatives

2001-11-13 Thread Jeremy Siemens
In the past I have thought of ways to enlarge paper negatives, but never got around to it (I just decided to build cameras that will take bigger paper negatives). One idea that I did have was to use a special projector that can project images from opaque sources. These projectors really exist,

[pinhole-discussion] Who we all are...

Aren't we pinholers a diverse group of people! Some of us hobbyists, some of us professional photographers, yet all interested in the same medium. I have contributed to the list once or twice, but I guess I'd like to re-introduce myself: I'm 25 and live in Toronto. No formal training in

[pinhole-discussion] Making the actual pinhole

2001-07-14 Thread Jeremy Siemens
Hi Joel, I read your message on the list regarding what size drill bits to use to make your pinholes. Personally I've had great success making my pinholes out of aluminum from pop cans (or soda cans if you prefer). The aluminum is very thin, not to mention cheap and plentyful. I use a sewing

[pinhole-discussion] Authentic vs. Technologically Manipulated Art Work

2001-06-27 Thread Jeremy Siemens
Thanks to David Ocampo for brining up this interresting topic. I think the discussion of whether artists should be true to their medium or whether we should embrace new technology applies to us pinholers because many of us are taking a minimalistic approach to a technologically advanced medium:

[pinhole-discussion] Remember that pinhole swap...

2001-06-22 Thread Jeremy Siemens
Just wondering... what is the average return rate for a pinhole swap group? For example, if 20 people agree to exchange photographs and, say, only 10 people actually mail their photos, is this an average return rate? This is, of course, a hypothetical situation. In unrelated news, thanks to

[pinhole-discussion] fibre optic pinhole

The best way to figure out what would happen if you used a fibre optic pinhole would be to just make one and see what happens. For those of us who are curious how fibre optics work, here's what I understand: (Sorry if this all sounds technical, but even pinhole photography must obey the laws

A few minutes ago my email program did something screwy, so this may be my second submission on the same subject. The subject was posted a week ago: designing a curved film plane camera that doesn't have to be changed in a darkroom after every exposure. One camera that I've made is actually

Edward, There are lots of things you can do once you've mastered the basics of pinhole. Since you've gotten this far you probably understand the priciples of photograpy and physics (as far as light is concerned). I recommend you begin experimenting with these principles. By manupulating the
