Join Brent Winebrenner for an in-depth discussion in this video Next steps, part of Lighting for Photographers: Flash Exposure.
In this course, we covered a lot of foundation material for working with manual strobes.…I discussed the exposure variables, the guide number math, and how the aperture,…flash to subject distance, ISO, and guide number scales interrelate to help you achieve equivalent…exposures when you're working with strobes.…I also showed you several shooting scenarios using more than one speed light.…But I kept my focus on lighting the model with just the key light.…In the shoot scenarios, we did do a few extra things that were beyond the scope of this course.…
However, I hope that after viewing these movies, you can see that using speed lights in manual…mode can really be fast once you understand the fundamentals.…After all, like mastering any other skill, lighting is a matter of practice and experience.…So. thanks for watching, and I encourage you to go out and try some of the technical exercises…you saw on this course.…I also encourage you to set up some creative shoots of your own.…And don't forget, guide number equals flash to subject distance times aperture.…
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.
