Looking at different digital cameras, even temperately costing digital cameras have arrangements for exposure compensation settings. To explain in a bit detail, the exposure compensation allows the users to control the amount of light entering the lens. And thereby the illumination of the photograph is decided. Exposure compensation can be altered manually or by the help of a digital camera’s exposure compensation setting that lets one override the metered exposure set inside the digital camera itself. Strictly speaking, the exposure values provide an expedient line of attack to put a figure on the available light intensity and therefore exposure.
As per general norms of the users of digital cameras, certain standards exist for selecting such values. These values are specifically known as Exposure Values (EV). Selecting an up to standard Exposure Values (EV) helps maintain the details contained in dark areas of a photo, or diminish the more than usually bright areas. Again, looking from technical point of view, the Exposure Values are numbers that refer to an assortment of combinations of apertures of lenses and shutter speed respectively. They have a selective range of values, ranging between -2 to +2 Exposure Values (EV). As a general rule positive exposure settings are used for cases where bulky areas of a scene are especially bright such as taking pictures of a snow scene and also during times of photographing when the background is a good deal brighter than the focal area under consideration. Also, negative exposure settings are used for cases where bulky areas of a scene are especially dark and also during times of photographing when the background is a good deal darker than the fore area under consideration.
One point that is worth noting is that light meters cannot see color. They deliver every scene as 18% middle gray and become accustomed to the exposure accordingly. And most digital cameras will allows a photographer to compensate the exposure by 1 to 2 EV plus or minus in 1/3 or 1/2 stop increments. A very important realization for any photographer is that the right exposure is only “correct” in the eye of the photographer; Exposure Value compensation can also be used as a creative tool.
