[pinhole-discussion] Camera Obscura
Da Vinci's musings about the 'Camera Obscura' so resonated with my feelings of mystery when using pinhole cameras that I included the famous quote in my web site: http://www.nh.ultranet.com/~stewoody/quote.htm
[pinhole-discussion] securing film holders to your camera
Some black, spongy-pressed foam around the edges of the box back that corresponds to the non-moving rectangle of the film holders will help with the lighttightness. Pressing the holder against the foam tightly can be done with a dowel rod. Sort of like the Leonardo pinhole cameras. Rosanne In addition to using the holders, you'll have to devise a method for securing them to your camera in a light tight fashion. I build wooden boxes and use a wood pressure plate sprung with the springy things you get in metal frame hardware kits.
[pinhole-discussion] new
I am new to the listserve discussion format. I am a beginning photo teacher at a Tempe Arizona high school. I use the pinhole camera as an introductory assignment, but feel I could go deeper into the technique. Anyone out there willing to share lesson plans, techniques or history?
Re: [pinhole-discussion] fiber optic pinhole
Jared McCaffery writes Fiber optic tubes are the thin plastic tubes often used in fiber optic decorations like false plant and light displays or fancy Christmas tree toppers, etc. Fiber optic tubing and cable is also used, in many different forms and factors, in the electronics industry. Light enters one end of the tube, reflect off from the insides of the tube until it reaches the other end, then exits the tube and is focused as a pinhole would be. You could think of it as a very long pinhole (not wide, but long rather). . rest of message cut. Fiber optic cable that is meant to just transport light won't preserve an image because the fiber strands are not kept in alignment. Endoscopes and things like that have to be made in a special way to keep the fibers aligned. A single strand might work as a pinhole, somebody should try it.
Re: [pinhole-discussion] The Camera Obscura
This quote should be on the WW pinhole photography day site and posters. Richard Heather lisa styles wrote: Leonardo da Vinci seems to have found the magic that we are all so attracted to in pinhole photography. If he were still around today I reckon he would be into this discussion group! Love the quote Lonnie, thanks :-) Before the invention of photography, here is what Leonardo da Vinci said about the camera obscura. Can you pinhole photographers relate? who would believe that so small a space could contain the image of all the universe? O mighty process! What talent can avail to penetrate a nature such as these? What tonque will it be that can unfold so great a wonder? Verily, none! This it is that guides the human discource to the considering of divine things. Here the figures, here the colors, here all the images of every part of the universe are contracted to a point. O what a point is so marvelous! --Leonardo da Vinci (1452-1519) Lonnie Paulson Minneapolis, MN USA

Re: [pinhole-discussion] Shim Stock
I just started w/pinhole photography and I want to make a better pinhole. For my first try I used aluminum from a pie plate. I'd like to get brass shim stock, but all the auto supply places around here have never heard of it. They look at me like I'm nuts when I ask for it. Do they know it as something else? Is there a better place to find it?

BTW, the same day I bought an 11x14 back! unfortunatelly the guy I bought the 8x10 from 6 years ago, had purchased the two 11x14 holders the seller had, he told he payed $90CDN each!!. Good price!! I'm pretty well done patching all the tiny holes in the bellows of my 11x14 view camera. I still have to tighten up the back to make it perfectly light tight and I'm off an running with the camera. If the snow finally melts down, I'll get out and shoot! It really a BIG camera! I only have 1 holder for the moment (plus parts to make one, perhaps 2 more), which is not much if I go out some distance away from my darkroom. I see holders every once in a while on eBay. They sell anywhere from US$100 to $200. Go to your nearest home improvement center and buy T nuts, this is what they look like: http://members.home.com/penate/nut.GIF If you can't find them, I could buy some I send them to you. I've never seen one before, but I'll print the image and bring it to the hardware store and ask for some. Many thanks for the info. If I can't find any, perhaps I'll call on you then. P.S. There is a hight probability that I show some work at Eight Elm in May during Contact 2001 I'll know better by the end of this week. Perhaps we could get together with Tina. I suppose that Lonsdale Gallery will have Pinhole work on their walls as usual. Cheers, Guy

Re: [pinhole-discussion] Camera backs
- Original Message - From: Guy Glorieux guy.glori...@sympatico.ca If you are not extremely handy, the best is to buy the actual backs of cameras. In the past and at photo fairs I have purchased an 8x10 metal back w/o GG for $5 and very recently a 5x7 metal back with GG for $10 Hm. This must have been some years ago. Or you have been particularly lucky, Guillermo. It seems that on eBay, these things sell for something more like US$100. The 8x10 I bought 6 years ago, I payed $10 Canadian and included a well used but light tight 8x10 film holder! I think that could qualify as my best bargain-purchase ever!!The 5x7 I bought in January/2001 is not that far though. I asked how much and the guy said: I don't know, my uncle is the owner and he just left for a moment, pls comeback. I came back twice more and the uncle still wasn't there, I cameback the last time before leaving the photo fair and still no uncle but this time there was a price tag fot the 5x7 back, the guy said the price is $20 CDN, I was absolutely surpriced, I was willing to pay up to $80. I said to the guy I'll give you $15 CDN and to my delight he answered: DEAL. BTW, the same day I bought an 11x14 back! unfortunatelly the guy I bought the 8x10 from 6 years ago, had purchased the two 11x14 holders the seller had, he told he payed $90CDN each!!. I do have an 8x10 back that looks vey much like the one you show. It is installed on a homemade pinhole box in wood. Looks really nice. I like the way you use a washer as a focussing tool before putting on the real pinhole or zoneplate. I will most likely do something similar to my camera. 8x10 film is not cheap and it's really nice to be able to frame your image before shooting. In case it was not obvious, I glued a square flat magnet at the back of the camera, the metal washer is then magnetically held in place, centered on the hole or right at one corner of the square. With the pinhole, you just glue it to another smaller piece of flat magnetic material that you place on top of the hole and held magnetically in place -of course-. What I find difficult is to fit a nut securely on the camera to connect to the screw on a tripod. Have you found a good way to handle that?

Aluminum may even be better, because brass seems more subject to tear in my opinion. I mount my pinholes in slide holders, marking the pinhole size on the cardboard. This helps to protect the pinholes from the abuse I subject them to when ripping them from one camera and applying them to another.
