Lighting for Photographers: Flash Exposure Fundamentals
Video: WelcomeExpand your lighting options and get the most out of your flash by learning the concepts and theory behind flash exposure.

Expand your lighting options and get the most out of your flash as photographer and teacher Brent Winebrenner takes a practical, hands-on look at the theory behind exposure, with a special emphasis on electronic flash exposure.
Even with today's automatic flash systems, there are good reasons to understand how flash exposure really works. Brent details these concepts in this course. The course describes how to calculate the true power of your flash and how to modify its output to match your needs, a technique that can extend battery life, reduce recycle time, and provide exposure control that is more predictable than fully automatic modes. The course concludes with several shooting scenarios during which Brent explores the creative use of gels, reflectors, and other light modifiers.
- Understanding exposure basics
- Reviewing aperture, ISO, and shutter speed
- Adjusting strobe power and flash to subject distance
- Finding the guide number of a strobe
- Making calculations based on ISO
- Understanding power ratios
Hi, my name is Brent Winebrenner, and welcome to Lighting for Photographers: Flash Exposure Fundamentals. The purpose of this course is to demystify Flash exposure and build a foundation for using strobes in manual mode. We are going to talk about the four exposure variables and how they fit together in a beautifully-integrated system. Then we'll dissect the variables that affect flash exposure. We'll discuss how to use our guide number to make exposure calculations, and I'll describe how these pieces fit together to create beautifully exposed images.
Finally, I'll light some scenes using speed lights in a real shoot scenario. I'll be using multiple variables in these shoots, but we'll always base our changes on the foundations that we established in the first chapters. So stick with me, and by the time we wrap this up, you'll have the information that you need to begin predicting your flash exposure results before you snap the shutter. You'll also have the start of a foundation that will help you begin tackling complex lighting problems. Now let's dive in to Flash Exposure Fundamentals.
