World pinhole day would have been last Sunday, April 24, but since that was Easter the folks how run the contest extended the time period by several days. (More about world pinhole day at http://www.pinholeday.org/)

Here’s my entry:

Of course, that is the South Haven lighthouse on the Lake Michigan Shore.

This was taken with my trusty Pentax 6x7 medium format camera with a pinhole body cap. The film used was some very old (and very expired) Kodak E100V transparency (slide) film.

I’m always trying to learn new things, so here are a few things I learned with this project:

1. The pinhole body cap does not form an entirely light proof seal against the camera body. In this shot you can see a mild light leak in the arching light areas to the left of the lighthouse. In some shots the light leaks totally whiles out the exposure. OK - I’m sure I was careless in how I mounted the body cap in a few cases, but I’m not sure if the body cap mounted on the camera is lightproof. (And then I wonder… why *should* a body cap be light proof, eh?)

I’ll be testing that…

2. The Kodak E100V had expired in 2004, but here we are, 7 years later, and it performed fine. It was stored in a deep freeze so that probably helped. I’ll be less worried about expired film going forward (good news since I have a freezer full of expired film…)

And BTW - I wouldn’t recommend slide film for any pinhole work, unless you can really get your exposure precise. I just really wanted to get rid of this film after looking at it in the freezer for the past 8 years, so I crossed my fingers and bracketed…
