Pixel manipulation refers to the process of altering individual pixels in a digital image. Each pixel represents a tiny part of the image and contains color information. By changing the values of these pixels, one can enhance, distort, or completely transform the image. This technique is widely used in graphic design, photography, and digital art. Common methods of pixel manipulation include adjusting brightness, contrast, and color balance. More advanced techniques involve applying filters or effects, such as blurring or sharpening. Software like Adobe Photoshop and GIMP provides tools for artists and designers to perform these manipulations effectively.
