Adobe Photoshop is a graphics editing program developed and published by Adobe Systems. Adobe Photoshop has ties with other Adobe software for example media editing, animation, cropping, notation and resizing an image and by creating special effects using filters and authoring.
The .PSD (Photoshop Document), Photoshop’s native format, stores an image with support for most imaging options available in Photoshop. These include layers with masks, color spaces, ICC profiles, transparency, text, alpha channels and spot colors, clipping paths, and duotone settings. This is in contrast to many other file formats (e.g. .EPS or .GIF) that restrict content to provide streamlined, predictable functionality.
