Instax Pinhole Howto

Last weekend after I put together that pinhole camera that uses instant film, I made a quick write-up and sent it off to the Lomography folks.

While I’ve been pre-occupied with health issues, it got published:

Instant Pinhole Photos

This is something I’ve been thinking about for a month or two. I enjoy pinhole photography, and am intrigued by instant film. So I wanted to combine the two – a pinhole camera that makes instant prints.

So this morning I finally decided to throw something together (in lieu of doing chores). I’ll post a detailed write-up of the construction later. The short version is, I used an Instant Back for the Lomo LC-A+ and built a pinhole-front to attach to the Instant Back. It was actually a very quick and easy project.

Here are some results:

Fuji Instax Mini film is rated at ISO 800, and I calculated the Instant Pinhole camera to have a 30mm focal length, and an aperture of about f/150. Under the overcast skies that came to about a 4 second exposure, which actually is a bit over-exposed I think. In the backyard, under heavy tree cover, this extended to eight seconds, which might be a bit under-exposed.

I tried some indoor shots but the Instax film suffers from big-time reciprocity failure – what should have been a 30-second exposure, looks like it would take over 2 1/2 minutes. So the Instant Pinhole is probably going to stick with sunny outdoor shots for now.
