alt Hacker NewsI recently bought a film camera (Minolta X-700) and I wasted a whole roll because I inverted the aperture (i.e, 2 = sharp, 32 = blur)...
I'm interested to see how the roll turns out - gave it for development the other day, had a good laugh with the employees though.
I now have a mnemonic for it: Blor - a (somewhat) portmanteau of Blur and low. So low aperture = blur.
Edit for clarification: I mean low number (2 vs 32) = blur

The larger the entrance pupil is, the narrower the depth of field is.
The smaller, i.e. the closest to an ideal pinhole camera, the wider the depth of field is. A an ideal pinhole camera has infinite depth of field.
Unfortunately the aperture f numbers are the wrong way round; larger numbers correspond to smaller diameters.
High aperture = Blur
Unfortunately the lower number actually means bigger aperture.
