Fractional Improvement

Isn't it funny how an obsession with photography can drive you to do some rather strange things?

Tonight I'm in the kitchen poking tiny holes through bits of Coke can and sanding them down in an effort to make the ideal sized pinhole to improve on this. First attempt was 0.05 mm too big but the second attempt was muct better at 0.33 mm (which makes a 'lens' of aperture f145).

Now the pinhole is mounted on a body cap and just awaiting an opportunity to use it outside....

PS - This is the second pinhole I#ve made in the last couple of days, the previous one was 0.387 mm (equivalent to f220) and will be mounted on this camera.

PPS - If you go in close you can just about see the pinholes!!
