For my "state of the art" camera's I use aquired very thin pinholes, but for my "fun work" with shoe boxes etc. I don't want to spoil my scissors with the (very hard) soda cans and use pet food aluminium trays or aluminium pizza bottoms instead. Far softer, easier to cut and also much thicker, but believe me, the thickness is not SO VERY important. The most important is YOU who takes the shot and decides what, when and how. Taco

Here it comes: Taco, It is actually very easy, the shutter/lens assembly come off by removing the lock nut at the rear and accessed thru the inside of the camera, use a screwdriver to turn the nut, once the assembly is off the camera, unscrew the very front of the lens, then you'll see another small lens also part of the front lens elements, this one is removed by removing a "C" clip. At the rear of the shutter there is another "C" clip that allow you to remove the rear lens element. I mount the new aperture in place of the rear element, this place the ZP, etc. 65mm or so from the film plane. I first mount the ZP on a plastic circle that fits snugly on the rear of the shutter, I usually use plastic from one of those 35mm canister's cap. Recently I have decided I will not use this cameras with their original glass, so I being making a hole in the center of the glass rear element and mount the aperture there. Guillermo taco

Re: [pinhole-discussion] 6x9 camera conversion
I went even further: I broke the shutter out and glued a pinhole in the place. From the outside it still looks like a Billy with all the stuff (distance, time, focus) but nothing works. With a small pinhole and Tmax 100 the exposing times are so long that it's enough to open the bellow just a little bit, quickly put your finger on top of the pinhole, open the bellow completely, take your finger away and after exposure do the same operation back. Exposure times vary between 20 and 120 seconds, so you have time enough. example shots can be found on http://www.users.pandora.be/pinholes/billy.html Taco "D.

What do you mean with panopin? 360 degrees or just "elongated"? If it's the lasr one, a suggestion: a)transform a Holga 120S into a pinhole camera (enough links one the net) and then: b)load her with 35 mm film! See http://www.theverb.com/holga/modification.htm or Kim Taylor who did the same with a Lubitel 166 http://www.toycamera.com/KTaylor/index.html If you are satisfied with 180 degrees, have a look on this page and scroll down till "Marina Klein Willebroek" http://users.pandora.be/taco/pinholes/mypinholes.html Taco
