    Post yer pinholes

    Looked back a few pages, didn't see any pinhole image threads. I've been messing around with them lately, was curious as to what other people are up to. This is taken with a homemade pinhole approx. f/220 shot at roughly 90mm on a Crown Graphic. 25m exposure on Foma 100 developed in Caffenol C-L

    Re: Post yer pinholes

    interesting thread! i'm new to pinhole and still learning stuff.. how do you make your own pinhole for your graphic? how do you manage to get the aperture size, focus on the ground glass, etc etc . i might try this on my graphic or make a dedicated 5x7 pinhole. i had leonardo 4x5 already but a DIY pinhole camera is much fun!

    my first two shots!

    Jim, very intriguing photo, I like it.

    Having dense moment though, could you explain this in a bit more detail?

    Exposure was varied from about 10 to 200 seconds over the length of the film by sliding a sleeve over the can.

    The proper exposure near the pinhole was about 10 seconds. At the far end of the can the exposure was about 200 seconds due to the greater distance from the pinhole and the image grazing the surface of the film. I added a loosely fitting sleeve of black paper outside the Pringles can. Sliding the sleeve up the can during the exposure first cut off the image near the pinhole and then the image further down. The rate of movement of the sleeve was approximately logarithmic, faster at first and tediously slow near the last. A logarithmic scale on the pringles can and a watch with sweep second hand timed the exposure. A tripod socket in the end opposite the pinhole and a sturdy tripod ensured adequate stability.

    Some great images so far, I'm glad to see this finally got some replies!

    In terms of making your own pinhole. I roughly followed this guide: http://www.withoutlenses.com/article...hole-apertures

    I used some thin brass sheeting I found at the hobby store, as well as quilting needles to make the hole. However, I didn't bother to buy a pin vice, I just stuck the needle into a rubber stopper that I had around and was able to apply enough pressure that way. I also used fine grade steel wool instead of sand paper to even out the surface, but I don't think that really made a difference one way or another. Finally, I mounted the pinhole on a piece of foam core with a hole cut in it to accommodate the brass square with the pinhole, and taped that to the inside of a regular graphic lens board. (I'll try to take a photo of it tomorrow).

    I believe, in theory, there is an optimum pinhole diameter for every focal length. Of course on a crown graphic, you have an adjustable focal length camera, but I was aiming for about a 90mm focal length as that's where I planned to do the most shooting. There are some good calculators at http://www.mrpinhole.com/ where you can figure out what size hole you need to drill to get a certain focal length and also what the f stop will be.

    I drilled my hole and then scanned the brass sheet so I could accurately measure the size of the hole on the computer, but in the end it's not like it has to be incredibly precise. I think that takes away some of the fun of working with pinholes.

    Ah, and I almost forgot. I don't focus, or I guess I should say frame since there isn't focusing to be done, on the ground glass, I just eyeball it. I did see somewhere, can't remember where, that someone had made a pinhole with a pretty wide aperture for framing on the ground glass and then would switch to a different pinhole to expose the image.
