Light reaches areas that are not in direct light by means of indirect light. The indirect light reaches the areas by reflecting off other surfaces.

It is important that the sensor receives the correct amount of light. To restrict the amount of light would produce poor results.
Light is usually measured in candle power or candellas. The temperature of the light is measured in degrees, kelvin. You'll find greater detail at the local library or through research on the internet.
Direct sunlight is extremely bright and results in washed out colors and stark contrasting shadows. Sometimes this lends to the subject or mood of the art. A sunny beach scene with sun glistening onto the shoreline or a morning figure washed in light through a bedroom window are examples of when direct light is king. In contrast when you use indirect light commonly called north light or reflected light the atmosphere is much more controlled. The value shift is more subtle resulting in far greater control over contrast. Colors can be presented in all their subtleties. Light from a north facing window has helped produce some of the greatest paintings in history. If you look at wonderful still life paintings you will see why north light is preferred many times. Vermeer is best known for his north lit room in which many of his paintings were produced.
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.
reflection
*Difuse* radiation is light that reaches the surface after being reflected and scattered by clouds or other particles in the sky. Direct is that light which has not been reflected.
from the light sorce
it creates a shadow
Direct. It is a chemical reaction.
Indirect light would be larger than direct light, because indirect light is from an angle, and it is usually dimmer.
Direct light is the light that comes directly from the light source to the place or thing that's being illuminated. Examples:The sun's light that illuminates unsheltered areas of Earth;A streetlight that illuminates everything within its beam;Indoor lighting that illuminates everything within its beam.Indirect light is light reflected from something that is not the source of the light. Examples:The light of the moon is light from the sun reflected to Earth or other regions of the universe. The moon does not produce its own light.The available light from a streetlight that is not within the range of its beam but can be used to see areas outside its beam.Indoor lighting that is directed toward the ceiling to create softer, diffused lighting for an area.
indirect covers a larger area but is less concentrated than direct light.
The tilt of Earth's axis gives more light to the areas experiencing "summer". The sunlight that reaches the Earth also depends on the average cloud cover.
Yes because it is a source of light. However, the moon is not direct light as it is not a source. It reflects the light of the sun and that is why we see the moon as 'shining.'
you direct light downwards
the light areas of the moon are called the highlands. the dark areas are called maria.
