What do you mean by falling into PS? Want to know why.

1, the calculation tool can be understood as an adder, and its function is to superimpose the images of two channels. Although the channel bar and the layer bar look very similar, the layer bar has an important feature, that is, there is a hierarchical relationship between the upper and lower layers, and there are many different ways to deal with the superposition between the upper and lower layers.

2. The calculation panel is divided into four pieces.

The first block called source 1 is the first channel to be mixed.

The second module, Source 2, is the second channel to be mixed. By default, it is the red channel of the current picture.

The third is the mixed mode and mixed transparency. The mixing method is exactly the same as the mixing of layers. Transparency is the transparency of the source 1.

The fourth block is the final output result. Because different from layers, channels can't influence each other basically, so after mixing, the new part will eventually generate new channels, new files and new channels.

3. Calculation is one of the powerful selection tools of ps, and it is also a powerful color adjustment tool. It provides accurate selection and makes the color transition in the selection natural in image synthesis and color adjustment.
