I'd like to start shooting some portraits that make use of sun flares. I'm going to do some experimenting over next week but thought I'd gather some thoughts here to get to a starting place.
I assume they're best done with a wide lens? Looking at the work of others, it seems that I want to get the sun partially blocked so it's more a point of light coming into the scene? How does a wide or small aperture impact the effect? How do I want to meter for the scene; spot meter on my subject or meter on the entire scene including the sun?
TIA.
