In Photoshop, the most primitive and simple method is to select and delete the areas with similar colors in the background with the magic wand tool, and then carefully wipe off some residual broken branches and leaves in the background with the eraser tool. Or use Lasso lasso tool to outline the main part of the image, reverse the selected area and delete the background. However, these methods can only be applied to some images with simple background, and the effect of matting is not ideal. With the improvement of Photoshop users' technology and the upgrade of software version, now we have more matting methods to choose magnetic lasso tools.

(Location: Toolbox)

Magnetic lasso is very useful when the graphics to be processed have obvious color contrast with the background. The more obvious the contrast, the more accurate the keying of the magnetic lasso tool.

Magic rubber tools

(Location: Toolbox)

The magic eraser tool combines the characteristics of eraser and magic wand tool. When you select the magic eraser tool, click the mouse in the image, and the areas with similar colors in the image will be erased. Especially for pictures with simple background, it is a good choice to use magic eraser as the key.

Background rubber tool

(Location: Toolbox) When there is obvious color difference between the foreground of your image and the background to be erased, you can consider using the background eraser tool for keying.

"Extraction" tool (extraction)

(Location: Menu-Image)

Extraction is a new function designed for "keying" in Photoshop 5.5, which is located in the image menu. You can select the layer to be processed in the layers panel, and then click image > extract menu, and a dialog box named "extract" will pop up.

Professional mask filter

(Location: Menu-Filter) Mask Pro filter has two important concepts: reserved color and discarded color. The reserved color is the color retained in the picture, and the discarded color indicates the color to be cropped. After determining these two colors, use magic tools to erase the discarded colors, and keying is successful. & gt& gt& gt details

Path tool

(Location: Toolbox, Path Panel)

Keying with paths is more suitable for images with complex contours and backgrounds.

Clever use of channels

(Location: Channel Panel) The method of separating objects from images by using Alpha channel is more suitable for dealing with people's photos and the like. People generally have hair, and wands may not be competent for such fine objects as hair, so it is very unrealistic to use path tools. Using the background eraser tool will destroy the "hair quality", while the magic eraser will make people feel powerless when wiping the tiny parts between the hair.
