What is the histogram of colors?
Color histogram in digital display is by accounting the frequency of pixels in a given image that has the same color. This is often transformed into a graph that helps to analyze and edit balance within the picture. Almost all photo editing software and a large number of digital cameras have the possibility of viewing or editing a color histogram. Editing the image by adjusting the color histogram can help clarify and improve the image by changing remote colors to the more common color from the image. These values can range from zero to 255, with no zero and 255 is the maximum value. If all three values are zero, the pixel is black; If all three 255 are, the pixel is white. The histogram determines how many pixels of each color are in the picture. It also shows how many pixels in colors are present according to intensity.
There are many uses for a histogram. The most important thing is that it can be used to edit images to help the image appear more professional by color consolidation. If the picture isFormed primarily midtones, then the histogram of colors can be adjusted so that the upper and lower colors change so that they are either absolutely white or black. This increases the contrast in the picture and causes visible midtons to look more vivid because they are framed by solid and white areas. It can also reduce pixilation by turning the areas of small pixels to solid paint.
on the digital camera can be displayed by the image. This can be very useful because the camera display - usually the liquid crystal display (LCD) - may not be able to show the important elements of the image precisely. Viewing the histogram can help determine whether the image has been excessively exposed or underexposed. However, not every camera has the possibility of a histogram and some that only provide a brightness histogram that is not always effective.
Using a color histogram with a camera is usually not suitable, except for control of excessive exposure, even then it may not be accurate. MeOne hundred should be checked from the camera using the histogram functions of the photo editing software and then compared to the histogram on the camera to visually calibrate how the camera determines its color histogram. However, some digital cameras provide the correct histogram of red-green Blue (RGB), which can be very useful after taking a picture.
