Lighting for a Standard Portrait

Here is my preparatory session for a standard headshot.

What worked well:

• Shot-through umbrella as a key light.
• Camera in full manual. Start with ambient only underexposed by 2 stops. Add one light at a time.
• Amazing retouching capabilities in Lightroom.
• When used with umbrellas,  speedlight should be zoomed manually to 24mm.  11mm diffuser is even better but results in light loss.

What did not work:

• Mixing light from a reflective silver umbrella and the one from satin shoot-through one.  Need to get another shoot through umbrella.
