Sunlight with speedlight
The speedlight is the Yongnuo YN465. This is a TTL type speedlight (also happens to have manual mode) so the camera body auto-detects its presence, and the usual flash menus in the camera are now applied to the speedlight instead. This is a modest speedlight, guide number is 33 (meters). TTL EV is left at 0 for this shot, camera EV is -1.5
