Fill foreground: alt+del Fill background: ctrl+del Foreground and background swap: x Restore default black and white: d
Invert the selection: ctrl+shift+i Cancel the selection: ctrl+d Free change (scale, rotate): ctrl+t (shift+alt: proportional scaling; shift: fixed rotation angle;)
Path change selection: ctrl+enter Cancel handle (control line): hold down alt and click on the anchor point to select the selection of the image in the layer: ctrl+layer thumbnail
Decolorize: ctrl+shift+u Stamp: ctrl+shift+alt+e (in the case of multiple layers, select the top layer to get an image of all current effects)
Group: ctrl+g Duplicate layer: ctrl+j Repeat last command (effect overlay repeat): ctrl+f
Bring the layer to the bottom: ctrl+shift+[ Bring the layer to the top: ctrl+shift+]
In PS, the rectangle is often enlarged and reduced with feathered edges, ctrl+t, and you can move one pixel up, down, left and right;
When the bottom layer of the clipping layer is a gradient, in the "Blending Options" - "Advanced Blending" of the style fx, click to check "Mix the internal effects into groups", and uncheck "Mix the clipping layers into groups" ”, you can make a clipping layer into the gradient layer;
A4: 210*297mm (positive degree 16K), 21*29.7cm (international) 210*285mm (large degree 16K), 21*28.5cm (domestic)

Resolution: the number of pixels per unit area;
Unit: dpi (print) ppi (image)
300+dpi--->Print
72dpi--->Webpage, UI, Inkjet
30dpi--->Super large printing
Color mode: RGB (red, green, blue) ---> image display, screen display CMYK (cyan, magenta (magenta), yellow, black) ---> printing mode
【Menu bar】->【Window】->【Arrange】：
Move to view the zoomed-in single background: space bar ---> gripper
Move both backgrounds at the same time: shift+space
Zoom in on both backgrounds at the same time: shift+space+ctrl
Zoom out on both backgrounds at the same time: shift+space+alt
Constituency:
Rectangular selection (m), role: can cut out, do modeling
Hold down the shift key ---> square, full circle
shift+m--->Switch rectangular selection and elliptical selection
(property bar) respectively indicate: selection | new stitching (plus selection) minus selection overlap
Irregular constituencies:
Lasso: used to modify the selection (new, addition, subtraction)
Polygonal lasso: used to create angular shapes
Magnetic lasso: with snap function (the color of the image edge and background should be contrasted)
Magic wand: make selection, cutout
Magic Wand Properties:
Tolerance: color range, the larger the tolerance, the larger the selection range
Continuous: Check ---> You need to click the selection area with smaller tolerance multiple times to adjust the selection area with the lasso; uncheck ---> Directly select all areas with similar colors
Feathering: The larger the feathering value, the more blurred the edge will be. You must first determine the feathering value before making a selection.
Crop Tool:
(property bar) to make a slanted image horizontal
pen:
shape, path, pixel
1. How to fix the point: at the end of a single arc
2. When to cancel the control line (handle): cancel the angle
3. The handle and the path maintain a tangent relationship
Text tool:
Operation 1: Click on the screen to enter text; submit text: 1. Check mark in the upper right corner, 2. ctrl+enter
Operation 2: It involves the use of text boxes for paragraphs (using the text tool to make a selection); advantages: modify the spatial layout of the text at will
Change the font spacing and line spacing in the paragraph, select (ctrl+a), in the selected state +alt, adjust the arrow keys
Layer operations:
1. Directly click the New Layer icon in the Layers panel
2. ctrl+shift+n pops up a new prompt
3. ctrl+shift+alt+n to quickly create
Projection production (physical projection):
Drag the material layer to the new layer, ctrl+t, right-click to flip, hold down the ctrl key to turn the white arrow to adjust the projection corners, ctrl+projection layer thumbnail, and then add a gradient to the selection
