Course Introduction：Use Photoshop to reduce noise by selecting the right tools and finely adjusting. First, select the "Reduce Noise" filter, adjust the intensity, retain details, reduce noise and sharpen details and other parameters to balance the noise reduction and image quality; secondly, RAW format photos can use the CameraRaw filter to achieve a more natural noise reduction effect by adjusting the brightness and color noise slider; finally, for local areas such as the sky or walls, "surface blur" can be used for precise processing to avoid overall blur affecting the realism of the picture.

Course Introduction：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.

Course Introduction：Adding film grain feel in Photoshop can be achieved through two methods; one is to use the "film grain" in the "film library", and after opening the photo, click Filter > Filter Library > Art Effect > Film Grains, and adjust the three parameters of light, highlight area and particle; the other is to combine the black and white adjustment layer with noise, and fill it with a 50% gray layer after creating a new black and white adjustment layer, add noise and set it to soft light or superposition mode, and use a mask to control the particles locally; when using it, be careful not to be too heavy to avoid affecting the main body. Use 3~5% of the small picture, and the large picture or printing can be appropriately enhanced, and can be used to light sharpen the details.

Course Introduction：The key to using Photoshop to convert photos into natural and textured painting style is to use filters reasonably, superimpose textures, and adjust colors and details. 1. Use artistic effect filters such as "oil painting" and "watercolor" in the "Filter Library" to adjust the parameters appropriately to quickly obtain the style effect; 2. Overlay the canvas or paper texture layers, and enhance the texture of the picture through "Soft Light" or "Overall" blending mode; 3. Adjust the color and contrast through tools such as "Hue/Saturation", "Curve", and "Color Balance" to enhance the overall atmosphere; 4. Finally, use "Intelligent Sharpening", "Liquefaction" and brush tools to enhance the edges and brushstrokes, making the picture more hand-painted. Each step should be kept natural and avoid over-treatment.

Course Introduction：To add pop art effects to the picture, Photoshop can be achieved through the following steps: 1. Select a portrait or still life with clear outlines and clean backgrounds to avoid complex backgrounds; 2. Use "desaturation" and "gradient mapping" to adjust the color, combine "color level" and "curves" to enhance the contrast, and use the "oil painting effect" filter to enhance the texture; 3. Add dots and thick lines, use the "half-toned pattern" filter or superimpose the dot texture material to enhance the comic sense; 4. Manually color or partial emphasis, use the "color" blending mode to highlight key areas such as lips or eyes. Mastering the primary and secondary relationships and color matching can easily create a PopArt style.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
