Let's say that you are taking a shot of a person but he is backlit by the bright sun, i.e. the sunlight is shining directly into your lens.
You ==> Person (subject) <=== Position of Sun (shining into lens)
What settings, filters, flash should I use to avoid silouetting the person & to see his face clearly.
If there is a mirror behind your subject in an indoor environment. How should I avoid a flash reflection.
