For a recent magazine feature, I deployed Profoto's lithium ion powered B1 studio light along with the Profoto 2x3 OCF OCF Softbox. TTL was used to generate a general flash exposure followed by manual adjustment. With minimal time allowed on location, the Profoto B1 provided a means for a powerful, self contained setup with minimal footprint. The light, stand and camera were brought to the location in a single Manfrotto stand bag, Profoto backpack, and Think Tank Retrospective 30 messenger.
