Want to take better pictures? Proper exposure is a critical part of that equation. The video above from Canon and photographer Arthur Morris teaches us settings to use for our DSLRs and how to use histograms.
It's an eight-minute video but a very useful one revealing pro tricks like using evaluative metering mode so the camera light meters take into consideration the whole image and "blinkies", which warn you if your shot will be overexposed.
