The application of the three primary colors principle that must be learned in the later stage of photography

In the white balance adjustment, we can find that the two ends of the color temperature are blue and yellow, which are just a group of complementary colors; The two ends of hue are green and magenta, which are also a set of complementary colors.

2. Curve

Curves are divided into RGB and trichromatic curves, and only trichromatic curves (red, green and blue curves) are seen here.

Red curve: according to the diagonal of the curve, the adjustment area is divided into two parts. If the curve is pulled up, it will increase red, and if it is pulled down, it will increase the complementary color of red: cyan.

Green curve: In the same way, it is divided into two areas, the curve increases green upwards, and the curve increases the complementary color of green downwards: magenta.

Blue curve: the curve increases blue upwards, and the curve increases blue downwards. Complementary color: yellow. Pull up the red curve, which means adding red to the picture. You can see that blue has turned into magenta, green has turned into yellow, and cyan is getting whiter and whiter.

Blue+red = magenta; Green+red = yellow; Cyan+red = blue+green+red = white. This can explain the color change of our picture, and we can adjust the color of the picture according to this principle later. Interested friends can use the curve to adjust the previous graph to see how it changes.

3. Color balance

The color balance is clear at a glance, and this is three sets of complementary color adjustment pictures. This function can add different color tendencies to the midtones, highlights and shadows of the picture in the later stage.

4. Optional colors

Among the optional colors, the previous complementary colors and equations are also applied to the color modification of the picture. For example, adding cyan to red, because cyan and red are complementary colors, adding cyan means reducing red, and red has completely disappeared at this time; So, how about reducing magenta in red? According to complementary colors, reducing magenta is increasing green. You can find that red plus green becomes yellow.
