attributes of light

Every source has five main attributes that affect the quality of light emitted and the overall lighting-look: 1) Hard or Soft (or in between); 2) Intensity (the amount of light); 3) Direction (in relation to the lens/subject axis); 4) Color (of light emitted); and 5) Beam pattern (the Beam Angle, shape, and any shadow patterns). All but color are affected by the light s Size and Distance, which may also be considered attributes.
