Natural light is comprised of sunlight or skylight. The former will produce distinct shadows, sharp delineation and enhances subject textures if it comes from one side (across the surface). This can emphasize the perception of depth in the scene. Direct sunlight often forces people to squint while the photographer places the sun behind his/her back. Without the use of corrective filtration, subject colors can shift towards warm/yellow hues quite noticeably when under direct sun in the early morning or late evening.
Skylight on the other hand, produces softer shadows and less delineation or texture enhancement. A slight color shift towards blue (cooler) may be noticed (compared to sunlight) since the sky color is closer to the balance of color film or digital sensors than the color temperature of direct sun. However, skylight can have one drawback when used for outdoor portraiture:
When a person stands outdoors in the shade of a tree, the area around their eyes often turns out very dark (raccoon like) in the photograph. This is because the effect of skylight is pleasing and easy to observe, but the amateur photographer doesn't notice the dark eye sockets produced by the large overhead source (the sky). This is why you will see any wedding photographer worth his salt balancing the ambient natural light with frontal electronic flash. If no flash is available, positioning the subject under the tree canopy will help. To produce this effect for observation, look at the subject's eye area while he/she dons and removes a Baseball cap. The visor on the cap will restrict the lighting to become much more horizontal, thereby reducing the raccoon effect.

Do most digital cameras offer the capability to control image quality and why would you ever want to take lower-quality images?
The "iso" control on a digital camera adjusts the image quality. As to why you'd want to...maybe there's enough light to take a best-quality picture at 1/30 second...but the thing you want to photograph has to be shot at 1/250 second. By adjusting the "iso" control to give you a grainier picture, you can use the shutter speed the picture requires.
How do cloudy days affect the light in photography?
The picture will just be a flash in a dark background, like a sun at night. This effect also happens when you take a photo of a brick wall.
What light bulbs provide the most natural light?
Any natural light bulbs that use incandescent lighting will work well, and give off a rounder light than the "sterile white" lighting of normal bulbs.
Can anybody define light?
define light and vision in relation to natural light and artificial light.
Is a light bulb artificial or natural?
artificial
How does artificial light affect the quality of a picture?
It cause a size difference.
How does the quality of light affect the perception of colour?
A better quality of light shows colors at their best, while poorer lighting makes colors harder to perceive. The four best lightings for color are natural, incandescent, ultraviolet and halogen.
What is the light source with light quality nearest to natural sunlight?
The sun.
How does exposure - aperture affect the quality of a picture?
The smaller the aperture, the more light enters the camera and onto the film. Also, the higher the aperture number the better the depth of field.
What are the three aspects of light that affect plant growth?
intensity duration quality
Does light affect food?
Yes, light is one of the things that causes food to spoil faster. This is true of both natural light and artificial light. This process is called photodegradation.
Is a diamond blue under black light less quality?
Some collectors of investment quality diamond gemstones object to this natural phenomenon, called fluorescence, others do not. You can read more about it, below. As to this phenomenon's affect on value, you can also read more about it, below, since there is no absolute 'yes' or 'no' consensus on the question.
Can you give me a sentence using the word beneficial?
"The bright natural light was beneficial to the photographer, it improved the quality of his photographs."
Why the film is being exposed in red light?
Film is exposed to red light because of the radiating influx of the temporical light standards, if the light came from a normal bulb, light that emitted from it would make it dull and not show the picture in full quality.
How do digital cameras form images?
There are two ways. First is vector way where picture is divided in elementary mathematical shapes, and you can change pictures dimensions without losing quality of picture. Second is raster, here picture is divided in points (pixels) and when you enlarge the picture you can see that pixels and the picture will lose quality. Most of pictures are in raster quality
What is the best DLP TV to buy?
Digital Light Processing type tvs are a step down in picture quality from direct view screens.
