photoshop tutorial: channel filling method to create alternative black and white photos – landscape color grading

Author Xishuangbanna Source: 5d6d
It is fast to produce pure black and white films, but it is slow to produce stylized non-color and non-black and white pictures. Generally, the channel filling method is used to quickly obtain an alternative black and white film with controllable expected effects, and then on this basis, the work efficiency will be greatly improved. Use this method to process human body pictures, and the effect is very good.

Landscape film renderings.

The following are detailed photoshop tutorial steps:

Open the original image. Convert to CMYK mode.

Open the Channels panel.

Press the D key.

Select the black channel, press Ctrl+left-click the mouse, and press Ctrl+Shift+l.

Select the yellow channel and press Alt+Delete.

Select the magenta channel and press Alt+Delete.

Select the cyan channel and press Alt+Delete. Then switch to Lab mode.

(The purpose of the above is to make the darker parts of the picture pure black.) The effect is shown in Figure 4.

Set the foreground color to neutral gray, H=0 degrees, S=0%, B=50%.

Copy the brightness channel, press Ctrl+left-click the mouse, press Alt+Delete; press Ctrl+Shift+l, press Alt+Delete; press Ctrl+A, press Ctrl+C.

(The purpose of this is to use the brightness map of the picture, which is clear and black and white, delicate, and has the richest levels.) See Figure 5

, select channel b and press Ctrl+V. The effect is shown in Figure 6

Select channel a and press Ctrl+V. The effect is shown in Figure 7

The distant mountains are too red, so select channel a, press Ctrl+left-click the mouse, and press Alt+Delete once. The effect is shown in Figure 8

complete!

Below is the result of processing another image exactly following the above steps.

How to achieve “controllable expected effects” using the channel filling method? Of course, you need to understand the color change rules of the fill channel. I have posted such tutorials before.

I also tried to use other methods to produce this kind of effect, but it was very tiring and not nearly as fast as this method! You might as well give it a try
