In photography, exposure relates to two factors: aperture or iris controls the amount of light transmitting on the film or sensor plane, while the shutter speed controls the duration of light transmitting on the film or sensor plane. These factors are reciprocal, meaning if you adjust one you must adjust the other to compensate for proper exposure. Changing the aperture affects depth of field or what is sharpest in the picture. The shutter speed affects the movement of the subject being photographed.

When taking photographs during the day with full sun exposure anywhere in the world, set your exposure to F/16 at 1/film speed. If using 50 an exposure index of 50 ISO, and want less depth of field or the sweet spot of the lens, simply open up two stops and close down two stops on your shutter speed. That would equal F/ 8 at 1/250. If it’s cloudy use your intuition and open up two to three stops to compensate for less daylight.

Inverse square law states that light falls off inversely proportional to the square of the distance from the source. Therefore, as the distance from your light source increases, you will have less luminosity, a “flat feel” and possibly increased color contamination. The closer a light source is to your subject, the more contrast or “punch” it will add and color will be less likely contaminated.

The fundamental strategy to lighting in photography entails a key light source, which establishes direction and feel. The fill light is implanted to increase the ratio of key light to establish a low or high key image. A background light, sometimes referred to as a kicker, hair, or rim light, separates the subject from the background, creating a more perceivable dynamic depth in the overall image. Consider using negative fill to subtract or white fill to increase key light.
