How to better understand and master hue saturation, brightness, contrast and sharpness in photography? . .

Tone: Normal color. Brightness can be understood as fresh vegetables that have been stored for a long time and vegetables that have just been picked from the ground. The negative ~ ~RPG is red, green and blue backwards. Output photos in black and white ~ black, white and gray.

Saturation: RPG value is adjusted year-on-year, the negative color is getting lighter and lighter, the lowest black and white, and the positive color is getting stronger and stronger.

Brightness: determines the brightness of the picture. If you want to take a dark picture in broad daylight, reduce the brightness.

Contrast: Increase or decrease the number of black and white colors in a photo. If you want to make the dark part of the photo pure black to remove redundant details, you can improve the contrast appropriately.

Sharpness: it is the sharpness of the picture. If you want to make your skin smooth and delicate, reduce the sharpness. When shooting sharp objects, in order to reflect the sense of sharpness, increase the sharpness value appropriately.
