I am going to do some sessions with kids outdoors over the next few weeks. They are not kids who will sit still or pose so they will be shot more like candids. I have a good lens rented and on its way but I am worried about lighting. I have a large reflector although I cant imagine chasing kids with a reflector. And know how to use fill flash (but rarely do). What times should I schedule shoots for (I live in Houston) or should i go to places that are shady? For indoor natural light photos, is there a best time of day?
