The magazine is worth picking up just for the shot of LaBeouf with the mermaid.
So what do we come away with from this? First, a lot can be done with a single light source. Yes, the sun came in to play here but much of it was cut out so that the Octabank could be the main light. Another aspect to notice here is how much production can go into a cover shot. The final image is very simple and clean but the work going into it can be quite complex.
Do you HAVE to have all that gear and crew to make amazing photos? No. Not at all. Having all that gear and crew give a photographer a lot of options. Heading out without all that gear will have you facing a number of limitations but this type of work can be achieved when you understand how light works, how to modify it, and how to control the environment. You probably will just have to wait a lot later in the day.
