To create and manage custom brushes, first create a black and white image or selection and define it as a brush preset, then design the brush shape by creating a new document or selection, and then save it using "Edit - Define Brush Preset". When organizing brushes, you can open the brush panel to create new groups and organize categories; adjust brush settings such as shape dynamics, scattering, and textures to optimize effects; finally export the selected brush as .abr files through the brush preset panel for backup or sharing.

Dithering is a technique that simulates more colors through pixel arrangement to reduce visual loss when color depth is reduced. When the image color depth is reduced, if it drops from 24-bit colors (about 16 million colors) to 8-bit colors (only 256 colors), a large amount of color information will be lost, resulting in a smooth gradient of ribbons or flat areas; dithering makes it visually blended by spreading pixels of different colors, thereby softening the transition effect. Its principle is based on the ability of the human eye to fuse adjacent pixels, making the overall vision close to the original image, and is especially suitable for low-color formats such as GIF, limited color support device display and digital art stylization. Whether to use dithering depends on the specific needs: ?Usage scenarios include converting photos or complex graphics to limited color tuning

Artboards is used in design software to manage multiple variants or screen layouts. Its core role is to organize design content, improve navigation efficiency, and facilitate delivery and display. They operate like standalone pages and can accommodate different screen sizes, design variants, or process steps such as mobile layouts, desktop versions, and dark mode. By grouping relevant designs, such as registration, boot, and dashboard pages in user processes and reasonably naming them, clarity and prototype link efficiency can be improved. With automatic layout and constraints, components can be reused across artboards and maintained consistency, and all instances are updated synchronously when modifying the main component. At the same time, you need to pay attention to file performance to avoid slowing down too many high-detail artboards. You can optimize file efficiency by hiding inactive artboards, reducing asset repetitions, and using variants.

It is not difficult to play Photoshop with a tablet, the key is to master several key points. 1. Install PhotoshopforiPad and log in to your Adobe account, enable automatic save, set gesture shortcut keys, and customize the toolbar. 2. Be familiar with the simplified interface layout and focus on mastering layer management, selection tools and modification tools. 3. Use ApplePencil to improve accuracy and set touch operation habits to improve efficiency. 4. Use seamless synchronization with the desktop version to achieve efficient collaboration between mobile editing and fine processing.

Mastering Photoshop shortcut keys can significantly improve work efficiency. 1. Zoom and Navigation: Z key activates the zoom tool, Space bar Drag the quick pan canvas, double-click Z key to adapt the image to the window size, Ctrl/Cmd/-adjust the zoom level; 2. Layer management: Ctrl Shift N creates a new layer, Ctrl G group, Ctrl E merges layers, Shift [or] moves the layer level, Ctrl Click on the layer thumbnail to quickly select content; 3. Select and brush adjustment: M and L to switch rectangular marquee and lasso tools respectively, Shift adds/Alt to subtract selections, [or] adjusts the brush size, Shift [or] adjusts the hardness, so as to achieve efficient editing and smooth operation.

Choosing the correct color mode depends on the purpose: 1. RGB is most suitable for screen display, because it is based on the three primary colors of light, and can present rich and bright colors, suitable for web pages, videos and digital photos; 2. CMYK is used for printing, consisting of cyan, magenta, yellow and black, with a narrow color range, and needs to be converted in advance during design to avoid printing deviations; 3. Lab is suitable for professional color tuning and color correction, independent of the equipment, covering a wider visible color gamut, and is often used in advanced image processing. If the work is only displayed on the screen, use RGB, and if printing is required, it should be converted to CMYK, and Lab is ideal when it involves fine color adjustments.
