Our guest host, photography expert, educator, and host of The Digital Story Derrick Story, covers photography 101 with Leo. Learn how to determine your strengths and address your challenges as a beginning photographer. Derrick shows Leo some of his favorite cameras and gear, and even gets into the basics of shooting great video.

Derrick's Tips

1. Master Your Flash. Dial back flash exposure compensation for a more natural looking fill light
2. Use regular exposure compensation and flash exposure compensation together for exposure mastery.
3. Lower your horizon. If you have a great sky, lower that horizon for more interesting images.

Derrick's Favorite Gears

• Canon 320 EX wireless flash
• Lowepro DSLR Video Fastpack AW
• Rogue Flash Benders
• Photoflex 5-1 Photodiscs
