What is a video histogram?
Video Histogram is a graph showing the distribution of dark areas, medium areas and bright areas in the video because it is recorded or played. By analyzing the video histogram, the cameraman can make filming to determine whether the image is properly exposed, and if not, adjust the camcorder accordingly. Videoographers who really know how to use a video histogram not only achieve better exposures, but also shoot cleaner video recordings than those who don't. They are column charts that represent the number of elements with a given value. For example, in a group of ten people, three of whom, four of whom, four own houses, two own two houses and one own three houses, which could be expressed on a histogram with left to the left, the next bar to the right, another bar over two and the right bar to one. This would graphically show a point that the Mlids in the Group own one home than any other number and that most people rent or own residences, unlike ownership of holidays or investment houses. VidEO Histogram works on the same principle.
Rather than graphs, how many houses a person own, video histograms show the number of pixels that have a given level of brightness. The Histogram side most is the dark tones, usually referred to as shadows, while the center represents midtones and the party on the right shows the division of peaks that are clear tones. A very dark image should therefore have a histogram with the peak on the side on the left and very lightly should the top on the right side. The histogram of a piece of black paper next to a piece of white paper would have two peaks - one dropped left and one on the right side.
Looking at the Vihistogram Deo, Videograph, it can ensure that the image is not excessively exposed, which would prove to the histogram as a large amount of pixels that get right or underexposed, which would show the opposite. In one of these cases, the cameraman could edit a video camera exposure or addAnother light. Videoographhers also use a histogram to shoot the brightest video as possible without overexposing it. The bright video not only attracts many viewers, but also provides a sharper and clearer picture with a smaller video.
