What Is a Camera Histogram?

Compared with traditional cameras, a big advantage of digital cameras is the LCD screen, which can be taken immediately. In addition to using it for framing, we can use it to check whether the people in the photos have their eyes closed, whether they have captured the scenes they need, and whether the results are satisfactory. Once the problem is found, you can delete the retake. However, the LCD screen of a digital camera is generally small in size and has low pixels. The display effect is often very different from the actual shooting effect. Once you enter the computer or output photos, it is easy to find underexposure or overexposure. This is unbearable for photography enthusiasts who are after image quality. At this time, we need to use another function of the LCD screen, that is, the "histogram display function".

Compared to traditional cameras,

A histogram is also called a histogram.

There are five typical histogram shapes, which correspond to different exposure conditions (the histogram display method of digital cameras and Photoshop are similar, so the histogram display on Photoshop is taken as an example for easy understanding):

Using histograms to guide exposure is a very practical method, of course, it should be based on your shooting subject. To accurately apply the histogram to determine the accuracy of the exposure, it is necessary to take multiple shots and practice. ^[2]
