Steve Berardi of Photonaturalist has a great post up on why you should memorize the ƒ number series. For those of us who are pulling our knowledge together, it’s a gentle introduction into some of the basic maths of photography. Ever wonder how ƒ stops get numbered? What is the difference between ƒ/1 and ƒ/1.4?

Thanks to Steve for this wonderful post! Go read it, and be sure to tell him you came from The Little Red Tent.
