Photoshop is a professional image editing and graphic design tool used for photo retouching, image manipulation, creative artwork, social media graphics, advertising materials, and digital content creation.

Raster graphics are made of pixels and are best for photographs and image editing. Vector graphics are made of paths and can be scaled without losing quality, making them ideal for logos and illustrations.

Image retouching is the process of improving the appearance of a photo by removing blemishes, correcting colors, adjusting lighting, and enhancing overall image quality while maintaining a natural look.

Layers allow designers to work on different elements of an image separately without affecting the original image. They provide flexibility for editing, organizing, and creating complex designs.

Resizing changes the dimensions of an image while maintaining all content. Cropping removes unwanted portions of an image to improve composition or focus on a specific subject.

Color correction adjusts colors, brightness, contrast, and white balance to make images look realistic, consistent, and visually appealing for professional use.

Background removal is the process of separating the subject from its background. It is commonly used for e-commerce product photos, advertising materials, and creative compositions.
