Darkroom Made
Pinhole camera?
I made a pinhole camera about a few months ago. After reading numerous how-to's online, I still dont get how the film aspect works. And another question, do ou think the Diana+ would be a better buy since it has a pinhole feature and requires no darkroom since it is 120 film?
The purpose of the pinhole camera is PARTLY experimental, but it has real and serious applications in a variety of applications should your demands be critical enough to require tremendous depth of field. Of course, the most obvious example of the use of a pinhole camera or lens is closeup photography.
I've never felt the need to build one myself but it would come in handy from time to time and it would be fun to try out. A 'real' technician could convert his or her existing SLR lens to pinhole aperature size-the task is not one for the faint at heart! I used to have the instructions for how to convert an SLR lens around here someplace, and if you haven't found instructions for doing that yet it may be worthwhile to look around if you are serious about pursuing the project to that extent. Of course, a digital SLR would be an outstanding way of messing with pinhole lens photography, but I'm not really sure how a DSLR would handle such a lens.
If you are interested in experimenting with it further I don't see any reason why it would do any harm to try the Diana if you have the money to put into it. While the 120 film does require darkroom processing that can be done by most labs, and the larger film format is certainly consistent with the concept of pinhole photography. BTW, speaking of interesting medium format cameras a friend of mine has a very large camera collection that includes a 'revolving' 120 camera; when the shutter is tripped, the camera rotates 360 degrees and makes ONE exposure of everything it sees in that rotation on a single roll of 120 film.
The principle of the pinhole camera is based upon the Camera Obscura, an ancient discovery that eventually lead to the invention of all sorts of optics and photography itself. A further search using that phrase may help explain how it works-if I am understanding what you are saying about the film aspect.
