Photographers refer to the hour just after sunrise and the hour before sunset as the golden hours. The light at those times will give the images a warm look and softer shadows; obviously it is a ideal time to be photographed. If you cannot schedule during the golden hours all is not lost. During mid-day sessions try to schedule in a location where there is shade available. Try to pick a location where the photographer can line up the light, either foreground, subject, and background all in shade or sunlight; lining up the light will improve the ovall appearance of the photograph. Make sure the photographer is equipped to shoot in mid-day light. Ask them if they will be using off-camera flash, reflectors and diffusers or other light modifiers. Light modifiers are basic tools of the trade and all good photographers use them.
