I’ve had several people asking if I can explain how I took the latest set of studio portraits. Here is the answer with the help of the Lighting Setup generator by Kevin Kertz.
The mainlight, a 150cm gridded octobox, was powered by a Profoto Pro-7a 1200W generator. The two hair lights, 30x120cm gridded softboxes, were powered by Profoto ComPact monolights. The generator was triggered with a PocketWizard which then triggered the two hair lights via their optical slaves. I used the Pentax 645D with a Pentax 67 105mm lens and a 67 to 645 adapter.
