New to pinholes/what about filters

I've just exposed my first roll of film (Tmax 100) in my Zero Image 6X9 and was quite pleased with the exposures (proper density). I used an Olympus OM 2S with a 21mm lens as my viewfinder and a Pentax digital spot meter to determine exposure. Guess I had my feet firmly planted in three centuries. The question I have is if anyone is using filters with their pinhole cameras and if so, how might they be attaching them? Any advice is appreciated. Bill Barber

Bill,

I usually use old Large Format shutters for my Pinhole cameras. The old Kodak slip-on, friction-fit Wratten filter holders (Series V, VI, or VII, depending on the old lens size) work quite well. I use the different filters such as the Aero Yellow, K2, Green & Red to change the contrast of B&W film- especially if I'm using out of date Polaroid (cheap!). I use a couple of the Color filters to warm up the usual bluish color shift, again especially with Polaroid.

You can tape a 55mm x 55mm plastic cut-to-size filters on the inside of the Zero Image, using black photo tape... I think that's what Zernike Au suggests on his site:

Happy Pinholing!

If you made the mistake of buying any Cokin filters, believing they had decent optical properties, now is the time to put them to good use by taping them in place. You may be able to use your standard glass filters by taping them in place. I think it would be easier to hinge a plastic or gelatin filter to drop over the pinhole when you open the sliding "shutter" of the Zero Image cameras. I haven't tried it but it looks feasible.

Just use an old filter with the glass removed. File down the male threads, glue the ring to the camera & screw in any filter of the appropriate size. (I used 58mm for clearance.)
