There are many simple matting methods, such as "quick selection tool", "magic wand" and "pen tool". I won't introduce it here.

Let me recommend a slightly more complicated matting method: channel matting (this method has a great contrast between the background color and the color to be cropped).

As shown in the figure:

Open the picture and click the channel.

And copy the channel with the largest contrast, remember to remove the eyes in front of RGB and red, green and blue channels.

Get the following picture:

Using the color code tool, the shortcut key "Ctrl+L" uses white and black straws to operate the green channel to get the black and white channels as follows:

Then hold down CTRL and click the copied channel with the left mouse button:

Go back to the Layers page and double-click the layer.

Use the reverse "ctrl+shift+I" to get the logo selection, and then press "CTRL+J" to copy and get the bottomless map of the logo.

Then drag the material to be placed and resize it:

I hope the comparison helps ~!
