The sunny sixteen rule states that a basic starting exposure (for film or digital still pictures) is the reciprocal of the film speed (back in the day ASA, now ISO) for the shutter speed at f16 for full sunny daylight exposures. Example bright sunny day no meter, or the reflective qualities would throw off a reflected (built in) light meter. You are using ISO 100, or your ISO is set at 100. Then your starting exposure would be 1/100 second at f16. or an equal value (EV). The lone lucky winner will receive a signed copy of my latest 4th of july abstract. Photos from this shoot will be post in a gallery at cross-photography.com by this Friday.
Remember to check your histogram for proper exposure. After the shoot is too late.
