Adobe PhotoShop CS5 Extended

Photoshop contains an endless selection of drawing tools, filters, color adjustment capabilities, and other tools designed to manipulate images in almost any way. Originally designed for bitmap images, Photoshop now incorporates vector drawing tools and layer design features, an expanded Web toolkit, and improvements to the user interface. You can use this program to edit photos in just about any way, from simply lightening dark photos to adding things or people that weren`t originally in a picture.
Though it`s an excellent software tool, the trial version demands a lot of time to download, a lot of hard drive space, and a lot of RAM for rendering and other heavy tasks. In addition, the trial version is save-, print-, and export-disabled, which limits your ability to assess this expensive product. Photoshop also has a high learning curve, so great results take time and training.
