2. Direction of Light
The direction of light is important because of shadows
,specifically those that are visible from camera position.
Before you shoot take a moment to consider your
alternatives
Directions of light affects shadows
3. Controlling Light
Size of the lens or the aperture openly controls the brightness of the light
The aperture size is indicated by its f-number or f-stop
The direction of light and its degree of diffusion affect the extent and intensity
of the shadows, the reveal texture, and suggest volume
Available light is the light that already exist in a scene
Artificial light is the light you bring to a scene ( Electronic flashes and other
flash units)
4. Diffusion
Diffusion affects the quality of light
Diffused light scatters onto the subject from many different
directions
Direct light creates hard edged light shadows
Directional-diffused light is partially direct with some diffused
or scattered rays

6. Outdoor and Indoor light
On an overcast day, at dusk, or in the shade, the light
will be diffused and soft
Available light indoors can be flat depending on the
source of light
Light indoors is often relatively dim
7. Lighting with flash
Flash units provide a convenient means of increasing the light, indoors or out
The burst of light from an electronic flash is very brief
Flash must be synchronized with the cameras shutter
The easiest way to light a scene with flash is with direct flash on camera
Manually controlled flash units emit a fixed amount of light
