Matt raises a good point here. Back about ten years or so when I decided to participate in WPPD, I made a pinhole lensboard for an old 4x5 I had. Thinking "wow -- microscopic aperture, better get some fast film" I bought some 400 ISO stuff. Alas, my exposures on a sunny day sort of fell into that no man's land. They were long by typical old time shutter standards, but rather too short to time accurately and consistently flipping something with the fingers. I wound up picking up some slower film to get up into the 5 to 10 second range.It seems that on sunny days, with some faster films, it is possible to find oneself in the situation where exposures on medium to smaller film might be in the shorter ranges - 1/2 - 3 seconds. So if you don't have a reliable way to make shorter exposures, you will need to take that into account when choosing film.

I'm hoping to shoot some colour transparency film too.I just made the exposure as short as I could manually with whatever film I had in there. If it was overexposed a few stops I just developed normally and hoped for the best. Never had too many unprintables as a result.

I am currently looking at a Zero Image 6x12 at a local shop that has the filter mount. The price seems really good at $215 USD. My only quam at this point is that it doesn't have a cable release. Is a cable release necessary for pinhole or will I be fine without. This is my first serious pinhole so I have a definite lack of experience.
Thanks Jim
I've been looking at those lately. Other than being quite pricey, they look like they have a lot going for it, especially in the weight department. How do you like yours? Was it worth the $$$? They're $400 here in Canada and then a film holder will be easily another $100 so it's quite an investment.I have an Ilford 4x5 pinhole camera and either use the dark slide or lens cap to start and stop an exposure. Always on a tripod.

Post a "Want to Buy" classified here on the website formerly known as APUG. You will probably be able to import one fairly easily, and there may be Canadians who have one they would be happy to sell.I've been looking at those lately.

I really dont understand. a) why filter-holder when you are using the cap. b) why lens-cap when you have a shutter.I have a Holga 6x12 that I modified with a 77mm filter holder. I never use filters with it though since they image on the film if there is any dust on them. Instead, I use a lens cap with flocking on the back of it. To make an exposure, I remove the lens cap but hold it in front of the pinhole, release the shutter, then remove the cap after a second or so. The results are much better since I started doing it this way. You could also just use a black card large enough to fill the image field, but the flocking absorbs over 99.9% of light. A cable release is nice, but you don't need one.

Update: 3s-krpc-Cosmos Circle(camera)-Shutter has B-setting(manually triggered(not advised) plus openclose-cable-connector. the cable needs a locker. 1/6 is possible like tested on Copal 1 with photoplug-sensor by filmomat(photoplug.de) Shutter is Copal 0-lensboard hole compatible, plates are not compatible with Skinkpinhole and Aupemierplan.The chinese shutter by 18°- 3s-krpc on ebay(store now accessible when account has admin-right(at least on my old winxp-pc) is now half-universal.
Pinholeplates by 18° are replaceable but not others can be attached. shutter for copal-0-lensboards. will get further informations.

i measured which exposure time can be reached with any cable-release(doesnt matter which type even true for grundner shutter with built in cable-release(two options): i used photoplug(dot de) shutter-tester. its 1/6 quickest with cable-release on simple pinhole-shutters.
I am now in discussion about other dimensions of the Cosmos Circle 4x5 camera.

confusions about tube 60mm and flange 70mm. true is: 58 or 65mm lens can be used on fixed 60mm tube. no helicoids possible here.
