Join Brent Winebrenner for an in-depth discussion in this video Applying concepts: Scenario two, part of Lighting for Photographers: Flash Exposure.
So, after we finished our second shoot, we turned right around, and we had this very…cool old industrial baler that was sitting there in the warehouse.…And so we decided to use this as a prop.…And it's relatively small, but it gave us some interesting lighting challenges.…The inside of it was a shiny metallic finish, and I wanted to kind of light that to give…a magenta glow around the model, and there were some slats in the walls of it that we…decided to utilize by blowing smoke into the scene, and backlighting it to create shafts…of light coming through this.…
So, we had a little piece of equipment that we used I think to great advantage as a background for our model.…So let's take a look at what we did. We'll start with the light camera right.…Lauren: So, I'll take this around to put green on it, or are you're going to put that front?…Brent: Yeah, you can put the green on it, and then we'll just use this other.…We decided to utilize a green gel on one of the strobes in the background and a magenta on the other.…
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
