F-Stops Explained By Penmachine

back in business

I’ve been talking a lot about f-stops lately, it seems, to people who own point-and-shoot digicams and wonder what all the numbers on my DSLR and lenses mean. Since my own photography knowledge isn’t derived from a classroom but a mental mashup of books, conversations with photographers, the internet, and a variety of other sources, I really don’t know if I’m synthesizing my learning into a coherent explanation of what that f/x really means.

Today, like an answer dropped right out of the sky, my RSS Reader served up a comprehensive post by Vancouver’s Derek K. Miller (Penmachine) which does the job quite nicely:

August 7, 2008: Camera Works: what are f-stops and why do they matter to the pictures you take?

If you’re allergic to math, don’t worry — the words will do the trick.

Thanks, Derek, I can stop stammering now.
