This is Sterling, who belongs to my dear old friends Mike and Amie.
He's a remarkable calm cat, which makes him a good model.
Repeated flashes as I tried to balance the exposure between indoor and outdoor light levels didn't faze him a bit.
The shade of his fur also allows for a perfect exposure that shows fine detail well.
San Fernando Cathedral.
For some reason, I only get crazy-looking lens flare at night when shooting churches, and it always follows the same pattern, as also seen here.
