Exposure is the amount of light that is allowed to reach each area unit of photographic medium when taking a photograph weather the medium being a film or image sensor. Manual exposure allows us to have full control over the exposure of our photos by turning the wheel on the lens of the camera. Manual exposure unlike automatic exposure allows us to take shots that we might not want to be fully focus to achieve a blurred look to a photograph.
Automatic exposure is a setting on most modern cameras that allows the user to completely focus on what they are taking a picture of and the camera will put the shot you choose to take in focus before you take it. The advantage of using automatic exposure is that you as a photographer can concentrate on taking extra care to keep the camera still if shooting free hand, it also allows you to get the best framed shot you can without having to worry about focus and exposure.
Colour balance is the global adjustment of the intensities of the colours (typically red, green, and blue the reason being these are the primary colours. The left half shows the photo as it came from the digital camera. The right half shows the photo adjusted to make a grey surface neutral in the same light.
White balance is adjusted in photography to ensure the colours in the photographs we take is as accurate as possible.

However in maximum 1:1 other uses it refers to a reproduction ratio, and a finished photograph of 18×24mm image a subject at greater than sensor, the on-screen life size. display of the photograph results in a greater than life-size image.
