Aperture is measured in “f” numbers.

Our camera is a digital point and click.  Inexpensive and easy to use.  I don't know anything about the science of taking good photos but that's OK - I know I'm not a photographer, don't pretend to be and I'm OK with that.

The software is Poladroid and is fun and can create some interesting looks.  Available for Windows and Apple.
