What is the channel calculation in ps?

The Calculate command is similar to the Apply Image command, and only folders with the same pixel size can participate in the operation. The difference is that the operation command can select the layers and channels of two source images, and the result can be a new image, a new channel or a selection. In addition, you can't select a composite channel in the "Operation" command, so you can only produce a grayscale effect.

There are two blending modes in the "Calculate" command that the layers and editing tools don't have: "Add" and "Subtract" to get a special composite picture.

That's all I know. Try it yourself.

Calculation is a channel calculation method (hybrid method) to synthesize a channel. Different from the application image, this method can select the synthesis result, and the result can become the first region or channel, while the application image cannot. Channel calculation is rarely used.

His calculation is like a mixture of layers. The blending of layers includes positive overlay, darkening and so on. There are so many modes of access computing. The difference is that the mixing of layers will not produce a new layer, but the mixing of channels will produce a new channel, which is produced by mixing two channels according to a mixing mode.

It's rarely used, but it's used as a constituency anyway.

Image application is that one image mixes some features of another image through image application, and calculation is a channel calculation method (mixing method) to synthesize a channel. Different from the application image, this method can select the synthetic result, and the result can be a region or a channel, while the application image cannot. Channel calculation is rarely used.
