Pinhole image

This is the first pinhole image I have made that I kinda think has a nice "feel" about it.

i like it
i like it ziggy-looks like an airbrushed painting-all good fun

what did you use as your pinhole camera? I have seen a technique which uses a pierced lenscap.

Hi Greg,

The pinhole (about 5 years old) is a piece of aluminum printing plate, dimpled (with a "hand graded" sewing needle) on one side and then the other, back and forth from one side to the other, all the while rotating the needle. After enough cycles, the aluminum becomes thin in that one spot and mushes up the aluminum around the spot. You use a very fine sandpaper to remove the high parts and continue the operation until you achieve a hole. (A piece of aluminum soda can also works well.)

After you drill a suitable sized hole, and you use the sandpaper for the last time, you need to coat the hole periphery. I used a black marker pen this time, but I have also used lampblack from a "detuned" oil lamp. (The lamp is set with the wick high, which produces soot, which is lampblack. You simply hold the aluminum plate over the sooty flame until coated lightly. A candle can also work.) I used the marker this time because I wanted a more durable pinhole.

I cut the hole from the sheet and mounted the pinhole onto an M42 extension tube, which allows me to add additional tubes, increasing the length (and focal length) as necessary.

This was shot using a short stack for 30 seconds exposure. I did use a kind of "lens" with this shot as well, but I'll explain later.

Thanks,

you cunstructed your own camera !! wow

Almost a 'cartoon' style with that tree standing 3D like that (to me anyway) Here are some of mine if you are interested. Pinholes are as raw as photography can get.

OK, the "lens" I used was an FD to EOS adapter behind the pinhole. The reason I used it was to compensate for some of the rectilinear distortion typical with pinhole images at short lengths.

I think it worked rather well, while preserving most of the desirable qualities of a pinhole lens.

Just an experiment that worked fairly well (instead of the usual results common to my "experiments".)

Just the "frontend". Canon did the rest (dRebel XT body).

The light was pretty low angle, but hadn't changed color yet.

I love looking at other people's work with pinhole, and I particularly like your motorcycle shots.

Thanks,

thanks for the explanation-a shot of some people in front of their house and next to their car in the driveway would look good usiing this technique-how about setting it up?
