This week Mark answers the question: "How many watt-seconds do I need?"
What are watt-seconds, and how many do you need? Mark Wallace takes several minutes to explain watt-seconds, how they influence the amount of light emitted by a flash, and what other factors may effect light intensity. He also does a comparison of the watt seconds and flash output of several popular studio strobes, and gets some surprises. Come along for an enlightening look into power and light in the photo studio.
