The use of flash can enable you to get quality results in a much wider variety of lighting conditions and can also allow you to capture images that are simply not possible without flash. In spite of this, it remains one of the least understood tools available to the photographer.
The goal of this class is to teach you several of the key underlying concepts that are critical to understanding how to use flash effectively. Topics will include the inverse square law, camera sync speed, front vs. rear sync, high-speed sync, the relationship between flash & ambient exposure, flash zoom, manual vs. automatic flash, and flash exposure compensation.
