This is my new favorite (and signature) lighting set-up.

A large umbrella (in this case it’s a 220cm soft silver skin) burning a 2.5K HMI with a soft-finish sundish burning a 1.2K HMI. Ridiculously pretty and completely impossible to identify when lookin’ at the pics. It allows for a hard-edge shadow while retaining sumptuous definition within areas left in the dark (hair, folds and creases in clothing, etc).
