Re: [pinhole-discussion] disposable camera pinholes
After much study (and dissassembly of several disposable camers), I have concluded that converting a disposable camera for pinhole use is usefull only if you really need the camera to be made at zero cost (which may well be the case if all the students in a class are doing it,), or if the builder likes the challenge of usng a camera that is designed not to be reloaded. For those who are looking for a simple, cheap, reloadable cameras to convert to pinhole, check resale shops and yard sales for the cheap plastic 35mm cameras that are often given away with magazine subscriptions. (The most common one in the US is from "Time" magazine, but there are others.) These camera have poor quality plastic lenses and unreliable shutters, but disposable camera conversions never seem to be able to make use of the original shutter either. So it doesn't really matter if the shutter that you remove is a good one or a bad one... The cheap giveaway cameras often have a curved filn plane, too (to compensate for a low quality lens) which may make for interesting effects with a pinhole. And you may be able to get this type of camera for free if you know someone who has one: they are unlikely to want to use it after the first attempt... The big advantage is that you don't need a darkroom or changing bag to load film.

Re: [pinhole-discussion] disposable camera pinholes
For those who might be getting a little confused (since the "how to make your own pinhole body cap" topic is now spread over several messages), the brill bit being discussed here is not being used to produce the pinhole that is used to take the photos. This drill bit is only used to make a hole in the plastic body cap that the actual pinhole (made in metal using the usual techniques) is mounted on the back of. As such, it needs to be large enough to not cause vignetting of the pinhole image which is why the question of size gets asked. I always figure that bigger is better, or at least safer. The cone shaped Dremel bit is a great suggestion, though I find it easier to use a regular drill to make a starter hole and then enlarge it with the cone shaped drill. Mike Vande Bunt D.

Sherry, You do not need a special drill bit - just one that isn't too big, nor too small - anything 1/8 inch and smaller is a good starting point. A useful bit is made for a Dremel Tool and is shaped like a cone. If you drill from the front, it makes a nice beveled edge. --- sherry rea wrote: > will someone please share the secret of making a > pinhole cmaera from disposable cameras and also is > there a special drill bit that should be used for > the > body cap pinhole? > > > thanks > > sherry > > > __ > Do you Yahoo!? > Yahoo!
