What are layer comps, and how do they help in presenting design variations?

Adjusting skin tone requires four steps in Photoshop: first, use the "Hue/Saturation" adjustment layer to adjust the body tone, select "Coloring" and slightly adjust the hue and saturation and cooperate with local processing of the mask; second, adjust the light and dark levels through "curves", brighten the midtones, darken the shadows and soften the highlights; then use "Optional Colors" to finely correct the color cast in the red, yellow and magenta channels; finally, combine "repair tools", "imitation stamps" and "Gaussian blur" for local modification and softening effects. The entire process should be gradually and carefully observed to ensure natural reality.

Lens distortion can be repaired through Photoshop various methods. 1. Use the "Adaptive Wide Angle" filter to draw the reference line along the straight line of the image to automatically adjust perspective and distortion, which is suitable for architectural photography; 2. Through the "Lens Correction" function, enable the configuration file to automatically correct barrel or pincushion distortion, and manually select the lens model and fine-tune the distortion value; 3. Use "Content Recognition Scaling" and "Deformation Tool" to manually adjust the edges and local areas, which are suitable for high-precision photo editing; 4. Turn on the grid to help improve the accuracy of correction. It is recommended to combine a variety of tools to obtain the best results in actual operation.

Photoshop can create animations, including GIFs and basic videos. 1. Set the workspace: Open the timeline panel, select frame animation or video timeline, and set the document mode to RGB; 2. Make GIF: Use each layer as frame, adjust the duration and number of cycles per frame; 3. Video editing: Switch to the video timeline, import video or image sequence, add transitions and audio; 4. Export animation: Select "Storage as the format used by the web" in GIF, and use the "Rendering Video" function to set parameters and export; 5. Notes: Keep the content concise to control the file size, suitable for short HD content creation.

Frequency separation In Photoshop, the finer picture editing is achieved by separating the skin texture from the color light and dark. The specific steps are as follows: 1. Copy the layers and name them separately, one layer retains the details, and the other layer applies Gaussian blur (radius 8~15 pixels); 2. Use the "calculation" function to merge the two layers to generate high-frequency parts, and set the blending mode to "linear light"; 3. Adjust the skin color in the low-frequency layer, and repair the details in the high-frequency layer, and do not interfere with each other; 4. If the skin is gray, check whether the blending mode, color adjustment position and blur parameters are reasonable. After mastering this technology, the photo editing effect is more natural and controllable.

Photoshop's FrameTool simplifies the image placement process through automatic masking function and improves design efficiency. To use the tool, first draw a rectangular or elliptical frame, then drag and drop the image onto the frame, and the image will automatically adapt to the shape boundaries. If the image position is inaccurate, you can use the mobile tool to adjust it. The image will not be distorted when the frame is resized unless it is forced to deform. In addition, the framework content options provide fill, adapt and crop modes for more precise control. Compared with traditional masks, the frame supports quick replacement of images and keeps the original image complete, which is suitable for multi-image layout designs that require frequent modification.

To make the picture become a tiled seamless map in Photoshop, the key is to eliminate edge seams. The specific methods include: 1. Use "Filter: Adaptive Wide Angle" to blur the edge hard seams, suitable for simple textures; 2. Manually copy and offset the edge content, and repair the seams with imitation stamps or patching tools; 3. Use "Pattern Overlay" to preview the effect, check and optimize the tiling performance.
