Zoned Out

The Zero Image 5×4 pinhole camera that I use has a rotating turret with a selection of pinholes and zone plates. Until recently I was using the basic frame which has just one pinhole and one zone plate, so as a pinhole user I set it to pinhole when I received it and never touched the turret again. However, recently I bought the deluxe version with not only a cable release but with three pinholes and three zone plates on the turret. The camera is modular and the idea is that as you add or remove additional frames (effectively changing the focal length) you slide in the appropriate sized pinhole for that focal length.

On a recent trip to Brighouse I was happily changing between pinholes as I moved between 25mm and 50mm focal lengths and as I packed the camera away I remembered to move the turret back to the 25mm setting.

Or did I?

Of course not; if I had this post wouldn’t have been written!

I next used the Zero Image in the local memorial park on Remembrance Sunday, intending to use the images for my “365” Challenge. However on developing the film all four sheets were fuzzy and not at all what I was expecting. I put it down to the lightweight tripod and the fact that I’d forgotten my cable release. I didn’t immediately spot that the negatives were rather dark, indicating over-exposure.

The following day I set out again with a sturdier tripod and two cable releases. After three sheets I decided to amend the configuration of the camera. As I went to move the pinhole in the turret for the new set-up I saw what the problem had been – when I’d reset the camera after my Brighouse outing I’d lined up not the pinhole but the zone plate!

Suddenly, all made sense. Fuzzy images and over-exposed negatives – not camera shake at all! A zone plate lets in more light than a pinhole so I’d metered “incorrectly” and zone plate images are naturally blurrier than pinhole.

So, will I be doing this regularly? Well, I hope that I won’t accidentally select a zone plate again certainly. As for the images themselves I’m not sure if they aren’t a step too far for me. I have happily embraced the soft, ethereal imagery of the pinhole but the jury is out on zone plate images. See what you think, time will tell if I deliberately set out with zone plate in mind but never say never!
