zAbout Histogram
|
|
| Number | A histogram is the luminance distribution that shows how many |
|
|
| pixels of a particular brightness exist in the picture. The | |
|
|
|
| |
|
|
|
| histogram display of this camera shows the brightness on the |
|
|
| of | horizontal axis (left side is black, right side is white) and the |
|
|
| number of pixels on the vertical axis. The exposure | |
|
|
| pixels | |
|
|
| compensation will change the histogram accordingly. Below is | |

Use the exposure compensation on the positive side.
Shooting with the exposure compensation on the positive side brightens the whole picture, making the entire histogram shift to the bright side (right side). If the exposure compensation is used on the negative side, the histogram will shift to the other side.

Both ends of the histogram consist only of data of 100% black or white*. Therefore, when the data is transferred to a PC later in order to compensate it, it is impossible to restore the area that has been blacked/whitened out. Checking the histogram allows you to know the status of the image beforehand.
*To be exact, a color image is expressed with RGB. Thus, the white is equal to R255, G255, B255, and the black is equal to R0, G0, B0.
