Here, I enlarged it to 8x10. http://holgamods.blinkk.net/images/limo.jpg This one was shot 'lomo style' from the waist as I was walking by the bank. This limo pulled up, and I didn't want them to know I was taking a picture. I believe it was 1/15 sec. I switched to plain text format, but that link is appearing in blue. I don't know if there is a html tag in there or if it's just my email client is recognizing it as a link. If there are tags in there, let me know and I'll look further into it. John

[pinhole-discussion] Re:Wood pinhole Camera For 4 X 5 Film
Guy The curling helped hold the film in place. I cut strips of cardboard to fill the rest of the holder at the top & bottom.The curl made it harder to contact print until I was done for the night and put the negatives away after 2hrs. Once I put them in sleeves they lined up pretty good This is the only shot I did to test a idea. This is the only shot I did with camera. I don't have a good eye for photography so I tend to make a camera & move on to the next one. Now if I could get black PVC 4'' drain pipe I could make just the back & different focal lengths.

I don't remember it (college physics was 25 years ago...). Almost any book on optics at your local public libraray should have it. (It is something very simple like "the focal length is equal to the diameter" or something like that.) Mike Vande Bunt

George, Go to http://www.cyberbeach.net/~dbardell/pinhole.html for some nicely built home made pinhole cameras Then checkout my site for the design calculators http://www.MrPinhole.com Larry --- Temi wrote: > I plan to build a pinhole camera out of wood that would use a 4 x 5 film > holder.

Thank you. --Temi All Images in the Pinhole section of my site, with the exception of "Jimmy" were made with this type of camera.

Re: [pinhole-discussion] Re:Wood Pinhole Camera For 4 X 5 Film
Dave, I really like the picture on the second page of your site at http://redbug19.20m.com/photo2.html The idea of using 3 strips of 35mm in a 4x5 holder is a new concept to me but it produces terrific results. It must have been quite something to load the strips and keep them in place despite the natural curling of the film.. Have you done more of these?

Thanks. Why didn't I think of that?
