Photoshop Practicals CS

Photoshop is Adobe's photo editing, image creation and graphic design software.

The software provides many image editing features for raster (pixel-based) images as well as vector graphics. It uses a layer-based editing system that enables image creation and altering with multiple overlays that support transparency. Layers can also act as masks or filters, altering underlying colors. Shadows and other effects can be added to the layers. Photoshop actions include automation features to reduce the need for repetitive tasks. An option known as Photoshop CC (Creative Cloud) allows users to work on content from any computer.

Open source alternatives to Photoshop include GIMP, a similar but free image editor that works on Mac, Windows and Linux.
