To learn photography, you must learn to look straight.

To learn photography, you must learn to look at histograms.

What about the histogram?

All black

pure white

black

shadow

neutral tone

highlight

white

underexposure

Normal exposure

overexposure

high-flown words

Low height contrast

Underexposure: The pixels in the shadow and black areas are piled up, the whole area is dark, and some details in the shadow area are lost.

Normal: Phase elements are piled up near the midrange, with relatively uniform distribution, distinct overall levels and rich details.

Over-exposure: pixels near high-light and white areas accumulate, and the whole picture is bright, and some details in bright areas are lost.

High-profile: The accumulation of pixel peaks in high-profile areas is called high-profile and the picture is bright.

Low-key: the accumulation of pixel peaks in the shadow area is called low-key, and the picture is dark.

Midtone: Most pixels are distributed in the middle area, which is called midtone.

Long tone: the bright parts in the histogram are widely distributed, so it is called long tone, which means that the picture has a sense of hierarchy.

Alto: The area where the bright part of the histogram occupies 2 13 is called alto, which is used in the evening.

Short tone: If the brightness distribution range in the histogram is small, it is called short tone, and the picture appears foggy.
