Photoshop is the industry-standard software used for digital imaging and graphic design. Unlike web development tools, it is a "raster-based" editor, meaning it works with pixels to manipulate photos, create digital paintings, and design complex layouts. It is most famous for its photo editing capabilities—like retouching portraits, adjusting lighting, or removing objects from a background—but it’s also a powerhouse for creating social media graphics and website mockups. 

The software operates on a layer-based system, allowing you to stack images, text, and effects on top of each other without permanently altering the original file. While it has a steeper learning curve than basic apps, it offers professional-grade tools like masks, filters, and AI-powered features that give you total control over every pixel. It is a core tool for photographers, designers, and digital artists who need to transform raw ideas into polished visual content.
