My last three attempts to take outdoor portraits were under extremely difficult conditions. Its late winter or early spring. So we have no leaves on trees to create shade and the time of the day was out of my hands. Early afternoon left me no building shade either. Not to mention zero clouds or over cast. My subjects were squinting and way to bright. Is it true that although not always but majority of the time you want your subjects in the shade? Also, please explain to me about your reflector. How important is a reflector and under what conditions do you use it or for what purposes?
