So today, frustrated that micro35 still isn't taking new orders and guerilla35 hasn't updated thier site since well before April 15th, I decided to toy around with some of the concepts using things I had around the apartment. My attempt would be to create a pinhole effect adaptor. Essentially I took a small cardboard box, mounted a paper screen inside, cut a hole for my dvx, cut a small hole on the oppisite side and then taped a few layers of aluminum foil over it, then punched a pinhole in it. After tweaking it a bit I finally got the faintest of images to show upwhen I looked through it, however not nearly enough for the dvx to pick up. After consulting a pinhole countrustion website, I determined that the widest equivelent F stop I could get would be about 190! That coupled with the paper screen would make the exposure almost impossible. If I used something with less light loss, I still don't think it will work. Am i barking up the wrong tree here or do you guys have any great ideas to make this work?
 
from the height of the experience of self building multiple pinhole camera with different materials and geometry, i can confirm that. the amount of light passing through the pinhole is so small that your exposures (with 35mm films) will be up to several minutes.

the fnumber can be 'calculated' (there are different theories and tables) from the hole-focal plane distance and the diameter of the hole.

if you enlarge the hole you get more light paying with focus loss. if you 're using dvx100a you might try setting it on slow slow shutter, high gain and see if you get some more.

i should be able to give you good technical links on pinhole if u interested

Who are you calling a pinhole?

Maybe because its 3:20inthe morning but what the heck are you guys talking about? Is there pictures of this crazy device you're making? thanks guys, I'm a little slow today.
 
pinhole camera is a photocamera with a tiny hole as a lens. it can be made out of cardboard, old tins, boxes. you just put a piece of film or light sensitive paper on the innerside of the box opposite to the hole. requires patience for long exposures and delivers weird dreamy effects.

Is a link with some info.
 
Thanks Andrea-
I hadn't made a real pinhole camera in a long time and forgot how long the exposure needs to be. Oh well, it was an interesting idea.
