high contrast histogram


If you come across this type of scenario, try to keep the light to the right side of the graph. Histograms of digital images provide a graphical representation of image contrast characteristics and are useful in evaluating contrast deficiencies such as low or high contrast, or inadequate dynamic range. High Contrast. The right histogram increases this gap between the intensity values and Whoo! the details in the image are now much more perceivable to us and thus yields a high contrast image. The custom setting is a high-contrast setting. A high dynamic range scene is essentially a high contrast scene. A low contrast image has one, only one peak, and its position is at the density level of the low contrast image, while the rest of the histogram might be flat at the bottom. When you look at the histogram, you should see the graph stretched into both directions. The histogram equalization process is an image processing method to adjust the contrast of an image by modifying the image’s histogram… So, for the high contrast, the image histogram should span the entire dynamic range as shown above by the right histogram. ... with each one accompanied by its histogram. The histogram in Figure 6 shows the image has almost no shading, only a flat area of white, and a flat area of black. High contrast histogram is also very typical. Explaining High Contrast. A very high contrast histogram can have two peaks, one far to the right, the other far to the left. Histogram Equalization. A high contrast scene is one where there are lots of very dark, and very bright tones, and perhaps not so many tones in between. In this case, your histogram will show data on the left and right, and not so much in the middle. Manipulation of the histogram can correct poor contrast and brightness to dramatically improve the quality of digital images. If you were to look at the histogram, a normal photo covers the highlights, shadows, mid-tones and everything in between. You will find some shots will have a very tall, very steep mountain somewhere in the center of the graph. The histogram displayed in the viewfinder is based on this. A histogram that is divided into separate columns of dark and light tones, with very few medium tones in between, indicates a very high-contrast rendering. High Contrast Scene. This is a typical high contrast scene, perhaps as in the example, a dark dog on snow. The image in the center is direct from the scanned negative, and the only modification I made to create the other images was increasing or decreasing contrast. Totally workable if you want a flatter look, or something to start from scratch with. A low-contrast (left), medium-contrast (center), and high-contrast (right) version of the same photograph. Most of its pixels are at the ends, and the peak value occurs on both the left and the right extremities. This is the RAW histogram for the same image.
