Shoot in shade
Flatter your subject by avoiding harsh sunlight and the stark, high contrast shadows direct sun can cause by shooting in the shade. This portrait was taken in Peru without any special equipment other than my camera. There was bright direct sun camera right that lit a patio that was out of the photo. Reflected light from the patio lit both faces, while the subjects were in total shade. Additional fill light was provided by reflection from the windows and wall camera left. The result was a flattering portrait with brilliantly saturated colors.
Taken with Nikon 24-70 zoom at 48mm, f 2.8, and 1/160 sec
