    Here we are. It is a forum for pinholers. Hope we all enjoy it and post nice pictures.
    I started to take pinhole photographs a couple of years ago and got trapped for the beauty of them. The simplicity and lack of gizmos its what attracted me most.
    I can enjoy now, the whole process. From visualizing an image up until mounting it.

    I am now with the idea of taking bigger pinhole negative and then contact print them therefore, no lens will be involved at all.

    I recently bought a pin holga from the Holga mods dude (http://www.holgamods.com/) but still have yet to use it. He also sells a pinhole body cap for Hassy 500 series cameras. Anyone use either of these? I'll have to play around with the exposure time but he does have a chart somewhere on his site that should get me somewhere in the ballpark.

    I've dabbled with pinholes for a few years, not really spending enough time on completed exposures to actually present it in any way. Most get scanned and posted on the web in 'see what I did' mode :smile:

    My biggest pinhole camera is an 10x7.9 (long story!) made from matt board. My most structural device is a 5x7 one made from masonite which zooms thru about 150 to 240mm. I recently bought a 4x5 neg holder to build into a 'Lenardo' style camera.

    Unfortunately I missed World Pinhole Day this year, but if you haven't seen the site, have a look (www.pinholeday.org), lots of piccies to browse.

    Aggie, it depends... you mentioned a Leonardo I think, so I guess you're going to use film? If you're using RC paper, it's EI is about 4. You need to know your pinhole diameter and focal length to work out an aperture. Use another lightmeter and extropolate (spelling?) to your aperture and film speed (if using paper). Easiest way of measuring your pinhole is to use your enlarger and measure the hole projected and divide by the magnification factor.

    I have a Finney pinhole body cap from Calumet that I can use on my Canon FD cameras (or any other cameras with a little gaffer's tape). It's of known size, so that's handy.

    My usual setup is to use it with an old shoe-mount Voigtlander Kontur finder for framing and 1600 speed film of some flavor. That usually gives me around 1/30 sec. in bright daylight.

    I try to shoot pinhole in hard light to get that pinhole glow off bright objects.

    I have heard quite a bit about pinhole photography recently and decided to "give it a go". I have purchased a plate for an EOS 600 I do not use so much now and wonder where to go from here. I intend to try it with Fuji Acros 100 which has extraordinary reciprocity failure figures so wonder what sort of exposure times I might be looking at. I realise the size of the pinhole is important but I cannot quote this at the moment.

    roy, to find a base time, mount the plate on the camera and measure the distance to the film plane. Ideally you need to know the diameter of your pinhole but I'm guessing it will be close to 0.3 mm. Divide the focal length (say it's about 40mm) by the pinhole diameter (40mm/0.3mm) and you end up with f133. f133 is not quite 1/3 stop more than f128 so I'd work on adding 1/2 stop over the f128 number I come up with. So, assuming Sunny 16 conditions, 1/60 @ f16 for your Acros (In my experiments, it's not an 100asa film), you'd need to add 6 1/2 stops (16-22-32-45-64-90-128+1/2) which gives a shutter speed of 1.5 sec (1/60-1/30-1/15-1/8-1/4-1/2-1sec-1 1/2sec) I'd shoot 1 and 2 sec brackets. Easy to compute than write down!

    For that "glow" you could try also a Zone Plate camera.
    Zero Image ( http://www.zeroimage.com/ )) makes good ones. I have a 6x6 one.

    In the same site go to : http://www.zeroimage.com/camera1.html

    Hi. I use a zero image pinhole camera. I just did a lot of film tests and wrote down EVERYTHING!!!! I prefer to only shoot pinhole. It's the most natural form of photography. If you would like you can check out some of my images here www.fotolog.net/daisyjellybean

    ciao
