• Everyone knows what photographs are. Not everyone knows how photography works, though. I'll admit, I've never had any formal training in photography, but this quiz represents a small culmination of my photo knowledge over the last several years. It's not all-inclusive by any means, and I may add more to this test later on if the response warrants it. BE WARNED: THIS TEST IS DESIGNED TO BE CHALLENGING! For anyone who doubts my expertise, I worked as a photojournalist for almost three years, a camera salesman for five years, and as a freelance photographer for two years. Criticisms and compliments are welcome.
