You’re photographing a wedding dress, and its white, right?
So, expose it 2/3’s of a stop below and then pop a light (with a honeycomb grid) on the face of the model and dial it in for the correct diffuse value exposure for the face – Bob’s you Aunty’s New Live-In Lover! and the dress will look right in the eyes of the typical viewer.
For today, that’s what’s in my
Line of Sight.
