I had fun meeting & photographing the instructors at Yes 2 Yoga. The owner, Donna Duffy, is building a new website and asked that I take headshots of instructors needing one. We met on a Saturday after classes were finished for the day and I took the photographs in the studio.
There are large windows providing a fair amount of light in the Yes 2 Yoga studio. I placed each subject with her face toward the window light. I wanted the flash to be fill flash and not the main source of light, so camera settings were: ISO 800, f/4.0, 1/60 sec. I used my 100mm fixed focal length macro lens and was sure that Image Stabilization (IS) was on.
I took a few extra photos of Donna.
Good luck ladies in all you do! Namaste.
