What does photography think of ww?

Histogram reflects the world "seen" by the camera lens, which is mainly used to judge whether the photo exposure is correct or not, and to avoid misjudgment due to screen, environment, personal preferences and other reasons.

The viewing rule of histogram is "left black and right white", with the left representing dark parts, the right representing bright parts and the middle representing middle tones.

Histogram has x axis and y axis.

Where x represents the brightness of the photo, and it is divided into brightness values of 0~255, with 0 being the darkest and 255 being the brightest.

The y-axis represents the number of pixels at a certain brightness. The higher the "mountain peak", the wider the division of this tone in the photo.

For example:

If the scene or object is dark, the histogram should be stacked on the left.

Conversely, if the scene or object is bright, the histogram will be stacked to the right.

I hope I can help you.
