Adam does an outstanding job taking you through his thought process, along with each step in how he's setting up the image. You really don't have an appreciation for the quality of the image above until you follow how he's set up a B1 and the gel outside along with the conditions inside.
In a recent "Why?", Sue Bryce talked about the importance of learning lighting and finding that balance to produce natural looking images. She also used Profoto B1's for the portrait she shared.
