i have been commissioned to do a very important shoot by either the sea OR in a desert for a family portrait. 1) do i shoot early in the morning (which might be difficult to arrange as children are involved etc), OR JUST before sunset? 2) if i do shoot at sunset or sunrise, do i need a lot of reflectors/diffusors? or should i just shoot wtih the availabe light i get, that should be quite soft anyway...? please advice. thank you.
