The modification of fat and thin in PS can be realized not only by one or two keys, but by extrusion with liquefaction tools. The following is how to use it:

Materials required: PS CS6 demonstration.

First open a picture, click "Filter" in the toolbar, and click "Liquefaction" in the drop-down menu.

2. After opening the liquefaction interface, click "Forward Deformation Tool" in the upper left corner.

Third, adjust the brush size of the tool and set the brush pressure to 50.

Fourthly, use the forward deformation tool to squeeze inward in the area that needs to be thinned, and the brush can be adapted to be larger, so that large-area extrusion can be carried out and deformation caused by small-area extrusion can be avoided.

5. Click "OK" on the liquefaction page after adjusting to be suitable for fat and thin.

Six, the effect is shown in the left picture below, and the right picture is the original picture.
