The people here at APUG are really good at infecting innocent people like me with new photographic viruses Browsing the APUG forum for a few days now, I also read some threads on pinhole cameras. I found that interesting, so last night I did some basic reading on it, and an hour ago I started building my very first pinhole camera! Being a rather impatient person, it had to go really fast, I wanted to see how it works and wanted to see the first exposure. I quickly drew the layout of a simple box on a piece of black paper, glued it all together with black gaffer tape and fixed it to the Pola back of my (stolen) MF camera. After half an hour my masterpiece of fine craftsmanship was finished. The biggest surprise was, of course, it actually worked and was lighttight. I neither have the skill nor was I in my excitement patient enough to make or get a good metal plate hole, so for this first try I simply punched a hole into the paper made box with a needle. Focal length: 90mm (3,54 in) Pinhole: 0.6mm (0.236 in) Film: Fuji instant B&W, 100 ASA, 6x6cm (MF), 1 year expired Exposure time: 4.5 minutes Light: 40W table lamp For your entertainment find attached to this post - the actual shot (me reading APUG during exposure. First one was black, second white, this is the third exposure. Seems like I assumed my pinhole camera to be a little more wide angle that it actually was) - my exquisite blue print for the paper box - a scan (don't have a digi at hand, d'uh) of the camera That was both great fun and an interesting experience. I felt a little like a kid on christmas. First thing tomorrow I'll do an outdoor shot, now it's dark over here.
