The Photoshop CS5 Image Editing Software from Adobe is the industry-standard application for editing photos. The software, compatible with Mac operating systems, gives you all the tools necessary to edit digital images.
Photoshop uses a powerful layer-based approach for image editing. Using layers allows you to make adjustments to images without modifying aspects of an original. You can modify layer opacity and order, aiding in compositing tasks. Photoshop keeps track of each change you make to an image, allowing you to undo actions with ease.
Photographers will appreciate Photoshop's robust photographic toolset and tight integration with Adobe's Photoshop Lightroom application. You'll be able to adjust image curves, remove noise from digital photographs, simulate film grain, add vignettes, and sharpen images. The software can open all types of images captured by digital cameras, including RAW images.
You'll also be able to correct lens distortions and image perspective. This is a powerful tool for architectural photographers who need to remove keystone effects from images and anyone shooting with ultra-wide angle rectilinear of fisheye lenses who would like to remove distortions.
Photoshop also supports the creation of High Dynamic Range (HDR) images. It can create an HDR image from multiple images of different exposures. It can remove ghosting created by slight camera movement between exposures, and you'll be able to tone images via intuitive slider controls.
Creatives will appreciate the tight integration with Adobe InDesign and Illustrator. Photoshop features a number of artistic image filters that can dramatically transform images. You'll be able to simulate different canvas types and brush strokes to create digital paintings. You can warp or stretch graphics, or move elements in images using the Puppet Warp tool.
Designers will appreciate the ability to isolate parts of images. You can cut out a model from a background with ease for use in a brochure. Photoshop is intelligent enough to correctly select complex parts of an image, including hair. You can go the opposite way as well -- you can remove a subject or object from an image and use the Content-Aware Fill to fill in the background with ease.
It is not without reason that Photoshop has become a verb in popular culture today. It's common to hear about someone who has "Photoshopped" a picture. Photoshop is the premiere application for image editing; it is a tool that every professional photographer and designer should have available.
