Once you have mastered the basics of how artificial lighting works and what you can accomplish with it, it is time to move on to more complicated multi-light setups to better bring your creative ideas to fruition. This great video will show you the process of creating a three-light portrait from start to finish.
Coming to you from Eli Infante, this helpful video will show you how a photographer builds a three-light studio portrait from scratch. Of course, multi-light setups are inherently more difficult, particularly when it comes to controlling the spill from all of them simultaneously. It is important to notice how Infante builds the shot light by light instead of trying to put them together all at once. By doing this, he can effectively evaluate how much power each light is putting out and if it is positioned correctly for its role in the shot. Once each individual light is working the way he would like, he can then turn them all on at once to create the final image. It is by far the easiest way to work with more complicated lighting setups such as this. Check out the video above to see exactly how Infante made it all come together.
Good stuff! :)
