Join Brent Winebrenner for an in-depth discussion in this video Applying concepts: Shooting scenario setup, part of Lighting for Photographers: Flash Exposure Fundamentals.
So, we're going into the warehouse, and we've set up three different shoots inside a very…small space, and the first one that we're going to take a look at is utilizing some…industrial ductwork that we've found in the building, and we are going to illustrate using…some different colored lights on the background to modify that background, and we're also…going to shake it up a little bit by shooting with two different focal lengths on the camera…to give us a wide portrait and then something that's a little bit tighter with a shallower depth of field.…So, here we go.…All right, so we've got this kind of high-tech background that we set up and what we're going…to do here is put a red gel on one of the background lights and a blue on the other.…
And we're going to let them cross in the middle and give us a nice magenta high-tech,…and then we'll put a neutral light on you, probably somewhere maybe right around here to get started.…And then we're going to drop a couple of lights into these tubes that kind of create some accents on the background.…
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
