Photoshop is almost the most commonly used software for our daily life or for pre-press production. Due to my work relationship, Photoshop is a must-have software every day, and I have constantly explored some experiences and tips from practice. Now I will introduce it to you, hoping to inspire readers.

1. When you want to change the spacing between two characters, place the cursor between the two characters and use alt + lift or alt + right to change the spacing between the two characters. When you want to change the character spacing of several characters, just select the character and use the left and right direction keys while holding down ctrl and alt to change the character spacing.

2. Use the shortcut keys to quickly browse the big picture: home, scroll to the upper left corner of the picture; end, scroll to the lower right corner of the picture; pageup, scroll to the top of the image; pagedown, scroll to the top of the image Bottom; ctrl + pageup, scroll to the far left of the picture; ctrl plus pagedown, scroll to the far right of the image.

3. To move the current layer up, use ctrl +] to raise the current layer one layer; press Ctrl + [to move the current layer down.

4. There are two ways to convert a color image into a grayscale image. One is to directly convert the RGB mode to grayscale, and the other is to convert RGB to LAB, and then throw away the A and B channels. Only the brightness channel is kept; practice has proved that the latter has a more delicate performance on the dark tone part of the image and less loss of dark tone information.

5. When you need to adjust the tone or contrast of the image, first convert the image with only an independent layer into a 16-bit channel, then adjust it, and then convert it back to an 8-bit channel after the adjustment, so that the image can be converted The loss of information is reduced to a minimum, and the effect obtained is much better than direct adjustment.

6. When the pattern to be cut out is very complex or has a very messy background, you can consider using the extraction in the filter. Setting the closed image, fill and response in the dialog box will make the cutout pattern very accurate. After making sure to use the history tool to make appropriate adjustments, you will get an ideal independent picture. This way can even help We squinted a fluffy kitten on the grass.

7. To use the newly used filter again, select Filter → Last Filter [Ctrl + F] from the menu; use the new option to use the newly used filter and remember to add an Alt key (Ctrl + Alt + F or Alt + Filter → Last Filter).

Tip: To exit the last filter or adjustment effect (or change the synthesis mode), press Ctrl + Shift + F (Filter → Fade Filter ...).

8. If you recently copied a picture and stored it in the clipboard, Photoshop will use the size of the picture in the clipboard as the default size of the new picture when creating a new file [Ctrl + N] (File → New ...). To bypass this feature and use the last setting, hold down the Alt key [Ctrl + Alt + N] (Alt + File → New ...) when opening.

9. Press the Ctrl + Alt + Z and Ctrl + Shift + Z key combinations to move backward and forward in the history (or you can use the menus in the history panel to use these commands). Use these hotkeys in conjunction with the [Ctrl + Z] (Edit → Undo) command to freely switch between history and current status.

10. The Alt + Backspace and Ctrl + Backspace key combination is to fill the foreground and background colors respectively. Another very useful hotkey is Shift + Backspace ?? to open the Fill dialog box.

Tip: Press Alt + Shift + Backspace and Ctrl + Shift + Backspace to fill only the existing pixels (keep the transparent area) when filling the foreground and background colors.

11. When using the free transform tool [Ctrl + T] (Edit → Free Transform), hold down the Alt key (Ctrl + Alt + T or Alt + Edit → Free Transform) to copy the original layer first (in the current selection) Then transform on the duplicate layer.

Tip: Ctrl + Shift + T (Edit → Transform → Again) is to perform the last transformation again, and Ctrl + Alt + Shift + T (Alt + Edit → Transform → Again) is to copy the original image and then perform the transformation.

12. To prevent the selection box from attracting to the picture frame when using the cutting tool [C] (Crop Tool), hold down the Ctrl key while dragging the control point on the selection box of the cutting tool.

13. To correct the tilted image, first use the measuring tool [U] to draw a line (like the border of the image, the door frame, the horizontal line between the eyes, etc.) on the map that can be used as a horizontal or vertical reference, and then from the menu Choose Image → Rotate Canvas → Arbitrary. After opening, you will find that the correct rotation angle has been automatically filled out. Just press OK to OK.

Note: You can also use the cutting tool to complete the rotation and cutting in one step: first use the cutting tool [C] to draw a box, drag the control point on the selection box to adjust the angle and size of the selection box, and finally press Enter to rotate and cut.

Tip: The angle measured by the measurement tool will also be automatically filled in the dialog box of the digital transformation tool (Edt → Transform → Numeric).

14. Use the "Create a new layer by copying [Ctrl + J] (Layer → New → Layer Via Copy)" or "Create a new layer by cutting [Ctrl + J] (Layer → New → Layer Via Cut)" command in one step. Complete the work of copy & paste and cut & paste.

Note: When copying (cutting) the new layer command, it will still be placed in their original places when pasting, however, copying (cutting) & pasting will paste to the center of the picture (or selection).

15. After cropping the image (using the crop tool or selecting Edit → Crop), all pixels outside the cropping range are lost. To crop without loss, use the "Canvas Size (Image → Canvas Size)" command instead. Although Photoshop will warn you that some cuts will be made, for some reason, in fact, not all of the "cut out" data is kept outside the screen.

Tip: ImageReady's cut command (Image → Crop) will ask whether to delete the cut area or hide it.

Note: This has no effect on the index color mode (using the canvas size command in index mode will lose pixels outside the screen).

16. Hold down the Alt key [Ctrl + Alt + Shift + E] (Alt + Layer → Merge Visible) when merging visible layers to merge all visible layers into the current layer.

Tip: You can also hold down the Alt key when merging layers (Layer → Merge Down), and the current layer will be copied and merged to the previous layer. There is no corresponding hotkey for this command ?? Ctrl + Alt + E does not work.

17. When using the Marquee Tools [M] (Marquee Tools), hold down the Shift key to draw square and perfect circle selection; hold down the Alt key to draw the selection area from the starting point as the center.

27. The coordinate origin of the ruler can be set anywhere on the canvas. Just drag from the upper left corner of the ruler to apply the new coordinate origin; double-click the upper left corner to restore the coordinate origin to the default point.

28. Using the path tool to create curve and diagonal auxiliary lines is also a good way. As long as the path is drawn with the pen tool, it can be used as a guideline when drawing or painting (the path always remains visible).

Tip: Use the hidden path command [Ctrl + Shift + H] (View → Hide Path) to switch the path display or not.

29. Auxiliary lines will not only be attracted to the edges (up, down, left, and right) of the current layer or selection, but also will be aligned with the horizontal or vertical center (of the current layer or selection). The reverse is also true: the same selections and layers will also be attached to the existing auxiliary lines (edge ​​and center).

Note: The auxiliary line will not be attached to the background layer. And to achieve the above function, you must first open the "close auxiliary line" [Ctrl + Shift +;] (View → Snap To Guides) option.

Tip: To find the center of the screen, you can create a new one and [Ctrl + Shift + N] (Layer → New Layer ...) and fill it with [Shift + Backspace] (Edit → Fill ...) a layer and then attach the auxiliary line to the vertical Center and level center.

36. Combined with the color sampler tool [Shift + I] (Color Sampler Tool) and the information panel (Window → Show Info), we can monitor the color change of the current picture. The color values ​​before and after the change are displayed next to the sampling point number on the information panel. The color mode of the sampling point can be defined through the pop-up menu on the information panel. To add a new sampling point, simply click anywhere on the canvas (using the color sampler tool), hold down the Alt key and click to remove the sampling point.
