![]() ![]() RGB : displays all the channels simultaneously (RGB and Luminance).However, you can also display the values per channel, as your camera does, by clicking on one of the buttons located on the right side of the chart: The histogram tool calculates the brightness values for each color channel, and displays them all together on the same chart. When the histogram is well spread out from left to right, with a nice peak in the center (corresponding to the midtones), the exposure can be considered balanced, with a wide dynamic range. If the histogram is shifted to the right, the image is brighter and, conversely, the more it is shifted to the left, the darker it is. In simple terms, the histogram is a graph showing the number of pixels per brightness level: the larger a vertical line, the more pixels there are at that brightness level. The histogram is the most convenient way to determine how an image has been exposed, in order to correct it effectively. This shows the histogram of an image with a CMYK profile, indicating the luminance levels in the Cyan, Magenta, Yellow and Black channels. The three color channels (RGB) and the Luminance channel can be displayed separately (Left: PC, right: Mac). The histogram shows, color by color, how many pixels there are for each level of luminance. ![]() The left pane of the Customize tab contains the following palettes (top to bottom): ![]() In this chapter, you will discover and learn all the tools, as they are arranged when you use the DxO Advanced workspace.
