Outdoor with source light (sun)

At the time of the shooting outdoor, with the help of one light source (sun). simply by using two reflectors, in order to reflect light from the sun so it is more efficient,

first:
as a key light, with a distance closer to the object

second:
as a fill light with greater distance from a distance so that the light reaching the objectis much fainter than the key light. 

three:
is the light from the sun itself as a back light
