What are the uses of saturation, contrast and sharpness in mobile phone cameras? When will it be adjusted?

Saturation: Saturation is defined as chromaticity divided by lightness, which can be understood as the purity and vividness of color. The higher the saturation value, the brighter the color of offside photos. On the contrary, the lower the saturation value, the more black and white photos tend to be. You can choose to adjust when shooting color objects.

Contrast: Contrast is defined as the brightness under the white screen (at the brightest) divided by the brightness under the black screen (at the darkest). The performance of contrast is that the greater the value, the more obvious the difference between the light and dark parts of the corresponding photos. On the contrary, when the value is low, the light and dark parts of the photo are basically unified. Contrast is usually used when shooting at night.

Sharpness: Also called sharpness, it can reflect the sharpness of the image plane and the sharpness of the image edge. The performance of sharpness usually appears in Meitu software. The higher the sharpness, the more obvious the clarity and detail description of photos. Therefore, the sharpness is usually reduced when shooting portraits.

Expand the relationship among saturation, contrast and sharpness in data mobile phone cameras;

Keenness is the premise of clarity. Sharpness is the combined data of contrast and resolution, or it is expressed by the combined data of sharpness and resolution. Resolution is reflected by camera and lens; And the sharpness is enhanced by the later period.

When the subjects are different, the photographer can reconcile the three data to achieve the best photography angle. In landscape photography, saturation, sharpness and contrast need to be enhanced to make photos more beautiful, but in portrait photography (especially for women and children), sharpness and saturation are usually reduced to remind contrast to depict more delicate portraits.
