Some basic concepts in Ps-Ps tutorial

Photoshop: it is one of the graphic processing software series developed by Adobe, mainly used in image processing, advertising design, a computer software. It was first used on an Apple machine (MAC) and later developed the forwindow version. Below are some of the basic concepts of this software Photoshop: it is one of the graphic processing software series developed by Adobe, mainly used in image processing, advertising design of a computer software. It was first used on Apple (MAC) and later developed for window. Below are some basic concepts in this software.

Bitmap: also known as a grating image, is generally used for photo quality image processing. it is composed of many "pixels" like small blocks. It is represented by its position and color value, which can show changes in color shadows. Photoshop is mainly used to process bitmap.

Vector: Generally, the physical properties of the image generated are not provided. it is generally used for engineering operation drawing. For example, it is difficult to show the quality of the light in a vector image.

Resolution: The pixel length per unit is called the resolution of the image. In short, the computer image is clear and blurred for the reader to watch. There are many kinds of resolutions. Such as screen resolution, scanner resolution, print resolution.

The relationship between the image size and resolution is as follows: the image size is large, the resolution is large, the file size is large, the memory size is large, and the computer processing speed is slow. On the contrary, any factor is reduced, the processing speed will be faster.

Channel: in PS, channel refers to the color range. generally, a basic color is a channel. For example, in RGB color, R is red, so the R channel range is red, G is green, and B is blue.

Layers: in PS, multiple layers are usually used to make each layer as a transparent paper. stacked together is a complete image. Modify each layer without any impact on other layers.

Color mode of the image:

1) RGB color mode: the color adding mode is the best color displayed on the screen. it consists of three colors: red, green, and blue. each color can have a brightness of 0.

2) CMYK color mode: it consists of blue, red, yellow, and yellow. it is also called the fading mode. This mode is generally used for print output and printing. Therefore, the CMYK mode is generally used for print images.

3) HSB color mode: the color is divided into tones, saturation and brightness by adjusting the tone, saturation and brightness to obtain the color and change.

4) Lab color mode: This mode uses one light intensity and two tones to describe a, and the other is B. It mainly affects the shade of the color. Generally, converting RGB to CMYK is converted by Lab.

5) index color: this color image uses one byte to indicate that it contains a maximum of 256 colors. The table stores and indexes the color used. The image quality is not high, A small amount of space is occupied.

6) gray mode: only black and white images are displayed. the Pixel 0 value is black, and the pixel 255 is white.

7) bitmap mode: Pixels are represented by binary instead of bytes. that is, black and white are represented by binary, minimizing disk space.

In PS 6, when the screen resolution is higher than 800X600, what is the bar box in the upper right corner?

When the resolution is higher than 600*800, there is a dark gray bar on the far left of the taskbar. you can drag and drop commonly used panels to save a lot of space.

How can I correctly display the Chinese font name?

Press CTRL + K and then remove Show Fonts Name In English.

What should I do when I enter and write half of the information displayed?

This is the reason for font. We recommend that you use "正" or "Microsoft" when using Xtep XX ". When the font spacing is not set properly, the font is half ....... There will also be problems with the Chinese "turetype" font.

What are the tips for using the Path tool?

When using the Pen tool to create a path, you can press the Shift key to force the path or direction to be horizontally, vertically, or 45 degrees. press the Ctrl key to temporarily switch to the path selection tool, hold down the Alt key and click the pen cursor on the black node to change the direction of the direction line so that the curve can be changed. press the Alt key and use the DirectSelection tool to click the path to select the entire path; to select multiple paths at the same time, you can press Shift and then click one by one. when you use the path selection tool, press Ctrl + Alt to move the path closer to the path and switch to the add and subtract node pen tools.

To switch whether the path is displayed, you can press the Shift key and click the mouse in the path bar of the path palette, or click in the gray area of the path palette.

To execute several macros (actions) together, you can first add a macro and then record each macro to be executed.

To add a new command after a macro (Action) command, you can select the command and click the Begin recording icon on the color palette, select the command to be added, and then click the Stop recording icon.

When using the Filter/Render/Clouds Filter, to generate more obvious support patterns, you can hold down the Alt key before executing this command; to generate a low-diffuse color effect, you can hold down the Shift key before executing the command.

When using the Filter/Render/Lighting Effects Filter, if you want to copy the light source in the dialog box, you can press and hold the Alt key before dragging the light source to copy.

To directly switch the Color mode on the Color palette, press the Shift key and move the cursor to the Color bar and click.
