What is PHOTO SHOP software? How to use? It’s best to explain a text with pictures! Thanks

Basic conceptual knowledge of Photoshop Photoshop: It is one of the series of graphics processing software developed by Adobe. It is a computer software mainly used in image processing and advertising design. At first it was only used on Apple computers (MAC), and later a version for Windows was also developed. Below are some basic concepts in this software. Bitmap: Also known as raster image, it is generally used for photo-quality image processing and is a graphic composed of many "pixels" like small squares. Represented by its position and color value, it can show changes in color shades. Photoshop is mainly used to process bitmaps. Vector graphics: Usually cannot provide the physical properties of images to generate photos, and are generally used for engineering and technical drawings. For example, the quality effect of lighting is difficult to express in a vector image. Resolution: The pixels per unit length are called the resolution of the image. Simply put, it is the clarity or blur of the computer image for the reader to see. There are many types of resolution. Such as screen resolution, scanner resolution, and printing resolution. The relationship between image size and image size and resolution: If the image size is large, the resolution is large, the file is large, and the memory occupied is large, the computer processing speed will be slow. On the contrary, if any factor is reduced, the processing speed will be accelerated. Channel: In PS, channel refers to the range of colors. Generally, one basic color is one channel. For example, RGB color, R is red, so the range of R channel is red, G is green, and B is blue. Layers: In PS, multiple layers are generally used to make each layer look like a piece of transparent paper. When stacked together, a complete image is formed. Modifications are made to each layer without any impact on other layers. Image color mode: 1) RGB color mode: also called additive color mode, it is the best color for screen display. It consists of three colors: red, green, and blue. Each color can have a brightness change of 0-255. 2) CMYK color mode: composed of royal blue, magenta, magenta and black, also called subtractive color mode. This mode is generally used for printout and printing, so printed images generally use CMYK mode. 3) HSB color mode: It decomposes colors into hue, saturation and brightness and obtains color and changes by adjusting hue, saturation and brightness. 4) Lab color mode: This mode uses a light intensity and two hues to describe one hue called a and the other hue called b. It mainly affects the lightness and darkness of the hue. Generally, when converting RGB to CMYK, it must be converted by Lab first. 5) Indexed color: In this color, the image pixel is represented by one byte. It contains a color table of up to 256 colors to store and index the colors used. The image quality is not high and it takes up less space. 6) Grayscale mode: that is, only black and white are used to display the image. The pixel value 0 is black and the pixel value 255 is white. 7) Bitmap mode: Pixels are not represented by bytes, but by binary, that is, black and white are represented by binary, thus occupying the smallest disk space. What is the purpose of the bar box that appears in the upper right corner when the screen resolution is higher than 800X600? When the resolution is higher than 600*800, there is a dark gray bar box on the far left side of the taskbar, where frequently used panels can be dragged and dropped, saving a lot of space. How to display Chinese font names correctly? Press CTRL+K, and then remove Show?Fonts?Name?In?English. How to deal with the situation where half of the text is displayed when typing and writing? This is the reason for the font library. It is recommended to use "Founder Font" or "Microsoft" when using extra bold XX. When the spacing of the fonts in the Wending font library is not set well, it is half. ... Hanyi's "turetype" font will also cause problems. What are some tips when using the Path tool? When using the Pen tool to create a path, hold down the Shift key to force the path or direction line to be horizontal, vertical, or at a 45-degree angle. Hold down the Ctrl key to temporarily switch to the path selection tool. Hold down the Alt key to place the pen cursor in black. Click on a node to change the direction of the direction line so that the curve can turn; press the Alt key and click the path with the Direct Selection tool to select the entire path; to select multiple paths at the same time, hold down Shift and click one by one. ; When using the path selection tool, hold down the "Ctrl+Alt" keys and move closer to the path to switch to the add node and subtract node pen tools. To switch whether the path is displayed or not, you can hold down the Shift key and click the mouse on the path bar of the path palette, or click in the gray area of ??the path palette. If you want to execute several macros (Actions) at the same time, you can first add a macro and then record each macro to be executed. If you want to add a new command after a certain command in a macro (Action), you can first select the command, then click the Begin?recording icon on the palette, select the command to be added, and then click Just click the Stop Recording icon. When using the Filter/Render/Clouds filter, if you want to produce more obvious branch patterns, you can hold down the Alt key before executing this command; if you want to generate a low-diffuse branch color effect, you can hold down the Shift key first. Then execute the command.

When using the Filter/Render/Lighting?Effects filter, if you want to copy the light source in the dialog box, you can hold down the Alt key and then drag the light source to copy. To switch color modes directly on the Color palette, hold down the Shift key and then move the cursor to the color bar and click. How to create a picture with a transparent background? First of all, only GIF can use transparency, so when saving the file, do not choose to save or save as, but directly select "Output GIF" and then select the transparent color. If the parts you need to be transparent are all white, select white, and then By analogy, when making pictures, hide the background picture and then save it for Web to make it transparent. When writing Chinese characters on a GIF, why are the writing discontinuous? First convert GIF to RGB, then convert it back to Index?Color after writing, select Image>Mode>Rgb/Image>Mode>Index?Color. How to use PS to make the reflection and back of an entity? For example, how does a bottle create its reflection and back? Duplicate the bottle and place it below. Make this layer black, then blur it, then put this layer Trasnform>Distort. After adjusting the proportions, adjust the transparency. Or directly give the bottle layer to Shadow or Outerglow, then separate the Effect layer, and then distort it. If you want to see the surrounding objects reflected on the back from the front of the bottle, you can use Render-3D Transform. This method is not as realistic as using 3D modeling. There is a filter Lens Pro in PS that can directly make glass. Reflections on surfaces such as balls. The reflection is in the water? ?Duplicate the bottle layer, flip it over, lower the transparency, and place it on the water layer. If it feels too clear, select Filter>Distort>Ripple and add some ripples. If it feels too stiff, adjust the bottle and water in Layer?Properties Color relationships between layers.
