“Tough”: This time around on we dissect a few sensors (no not literally), HDR Photography, Charlie walks us through Ian Ruhter’s big blue camera truck (again, not literally) before we get to the bottom of just what aperture is and what on earth F-numbers do, AND rejoice in our very first listener submission! There’s plenty more too so sit back, fill yourself with tea or hot chocolate (not... literally...) and see where we take you! DISCLAIMER: literally speaking, we take you nowhere. Enjoy!
