In photography and image processing, color balance is the global adjustment of the intensities of the colors (typically red, green, and blue primary colors). An important goal of this adjustment is to render specific colors – particularly neutral colors – correctly; hence, the general method is sometimes called gray balance, neutral balance, or white balance. Color balance changes the overall mixture of colors in an image and is used for color correction; generalized versions of color balance are used to get colors other than neutrals to also appear correct or pleasing.
Image data acquired by sensors – either film or electronic image sensors – must be transformed from the acquired values to new values that are appropriate for color reproduction or display. Several aspects of the acquisition and display process make such color correction essential – including the fact that the acquisition sensors do not match the sensors in the human eye, that the properties of the display medium must be accounted for, and that the ambient viewing conditions of the acquisition differ from the display viewing conditions.
The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable hue to that of the light source. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. In practice, color temperature is only meaningful for light sources that do in fact correspond somewhat closely to the radiation of some black body, i.e., those on a line from reddish/orange via yellow and more or less white to blueish white; it does not make sense to speak of the color temperature of, e.g., a green or a purple light. Color temperature is conventionally stated in the unit of absolute temperature, the Kelvin, having the unit symbol K.
Color temperatures over 5,000K are called cool colors (bluish white), while lower color temperatures (2,700–3,000 K) are called warm colors (yellowish white through red). This relation, however, is a psychological one in contrast to the physical relation implied by Wien's displacement law, according to which the spectral peak is shifted towards shorter wavelengths (resulting in a more blueish white) for higher temperatures.
White is an achromatic color, literally a "color without hue", that is a mixture of the frequencies of all the colors of the visible spectrum. It is one of the most common colors in nature, the color of sunlight, snow, milk, chalk, limestone and other common minerals. In many cultures white represents or signifies purity, innocence, and light, and is the symbolic opposite of black, or darkness. According to surveys in Europe and the United States, white is the color most often associated with perfection, the good, honesty, cleanliness, the beginning, the new, neutrality, and exactitude.
In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore a white toga as a symbol of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity; the widows of kings dressed in white rather than black as the color of mourning. It sometimes symbolizes royalty; it was the color of the French kings (black being the color of the queens) and of the monarchist movement after the French Revolution as well as of the movement called the White Russians (not to be confounded with Belarus, literally "White Russia") who fought the Bolsheviks during the Russian Civil War (1917-1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches, capitols and other government buildings, especially in the United States of America. It was also widely used in 20th century modern architecture as a symbol of modernity, simplicity and strength.

White Balance: We use B+W circular polarizer. They get rid of the reflections from water, windows, and most plants/green things. We use them whenever the sun is out. When buying a polarizer make sure to get the right size for the lens that you own. I feel if your going to spend the money and buy an expensive lens, it's worth spending the extra money to buy a polarizer of the same quality to match your lens, otherwise your lens won't be as clear. Plan on spending about 130 dollars US for one. B+W 77mm Circular Polarizer http://amzn.com/B00OK6YSAS Learn even more about Polarizers here: http://camerapedia.wikia.com/wiki/Pol...

You need to know how to set your white balance so you're photos are the correct colour. It's the first step in a colour managed workflow. So why is White balance so important? Light has many different colours. Even daylight changes colour as we go from warm reds around sunrise, through cooler colours at mid day and back to red again round sunset. If it's cloudy the light will be blue and in sunshine it'll have a yellow content. Shade is similar to cloud in it's blueishness (think I just invented that word) and domestic light can be all sorts of colours. White balance is measured in degrees Kelvin which give you what's called your colour temperature. You don't really need to worry about the numbers, but I think it's interesting to know white balance and how it's measured begins in a black...

To me the iPhone 7 Plus is the more interesting model as it features a new dual camera system. One camera will feature a wide angle lens and the other will be telephoto. This will allow for optical zoom and alternate photo / video framing options.
