White Balance in digital photography means adjusting colors so that the image looks more natural. We go through the process of adjusting colors to primarily get rid of color casts, in order to match the picture with what we saw when we took it.
Daylight- Daylight has a spectrum similar to that of a black body with a correlated color temperature of 6500 K (D65 viewing standard) or 5500 K (daylight-balanced photographic film standard). Definition: Noun: (1) Light that comes more or less directly from sun: it varies very widely in brightness, colour and quality. (2) A notional standard light: an average mixture of sunlight and skylight with some clouds typical of temperate latitudes around midday.
Shade- If you have a reflector—which can be something as simple as a white sweater or sheet—try bouncing light onto your subject to brighten them up. Here's a trick for when you're shooting in shade: open your exposure up. This means you slightly over-expose the image, or expose for the shadows.
Fluorescent- Fluorescence photography. Written By: Fluorescence photography, process that records the glow or visible light given off by certain substances when they are irradiated by ultraviolet rays.
Tungsten- An image taken under tungsten bulb (a normal household incandescent bulb) without adjusting the digital camera for white balance produces the dull orange shade as it spreads the biased light. Similarly, an image taken under the fluorescent lighting produces a brighter bluish cast.
Flash- A flash is a device used in photography producing a flash of artificial light (typically 1/1000 to 1/200 of a second) at a color temperature of about 5500 K to help illuminate a scene. A major purpose of a flash is to illuminate a dark scene.
Cloudy- Most photographers know that a cloudy or overcast day produces really soft light that can be flattering on the human face. ... Sometimes, most of the time overcast light is actually pretty boring and removes any and all contrast from your scene.
