6-5 Adjust channel curves individually – Beginner’s Tutorial
Until now, we have all adjusted in the RGB integrated channel of the curve. In fact, for images in RGB format, the curve of a certain channel can also be adjusted separately. The concept of curves in the individual channels is the same as in the integrated channel, and is also divided into highlights, midtones and shadows. In the color principle of course #01, we learned that pure white is composed of RGB at the highest luminous level, and pure black is composed of RGB that does not emit light. After mastering the principles of RGB color composition, it will not be difficult to look at individual channel curves. And if you haven’t fully mastered the color principle, it will be quite difficult. For a given image, changing the curve of a channel alone will cause color shift. It’s very simple. If you increase the middle adjustment of the red channel curve toward the Y axis, just like the adjustment we just made on the learning curve, it means that the red color is increased in the image, and then the image must be biased toward red. If you add green, it will look greener, and if you add blue,…
