Adobe Photoshop, or simply Photoshop, is a graphics editing program developed and published by Adobe Systems. It is the current and primary market leader for commercial bitmap and image manipulation, and is the flagship product of Adobe Systems. It has been described as "an industry standard for graphics professionals"and was one of the early "killer applications" on Macintosh.
Photoshop CS1, the current tenth iteration of the program, was officially announced on 23 September 2008 and released on 15 October 2008. "CS" reflects its integration with other Creative Suite products, and the number "3" represents it as the fourth version released since Adobe re-branded its products under the CS umbrella. Photoshop CS3 features additions such as the ability to paint directly on 3D models, wrap 2D images around 3D shapes, convert gradient maps to 3D objects, add depth to layers and text, get print-quality output with the new ray-tracing rendering engine, and enjoy exporting to supported common 3D formats; the new Adjustment and Mask Panels; Content-aware scaling (previously known as seam carving); Fluid Canvas Rotation and File display options . On 30 April, Adobe released Photoshop CS3 Extended, which includes all the same features of Adobe Photoshop CS3 with the addition of capabilities for scientific imaging, 3D, and high end film and video users. The successor to Photoshop CS3, Photoshop CS4, is the first 64-bit Photoshop on consumer computers.
Photoshop has strong ties with other Adobe software for media editing, animation, and authoring. Files in Photoshop's native format, .PSD, can be exported to and from Adobe ImageReady, Adobe Illustrator, Adobe Premiere Pro, After Effects, and Adobe Encore DVD to make professional standard DVDs and provide non-linear editing and special effects services, such as backgrounds, textures, and so on, for television, film, and the Web. For example, Photoshop CS broadly supports making menus and buttons for DVDs. For .PSD files exported as a menu or button, it only needs to have layers, nested in layer sets with a cuing format, and Adobe Encore DVD reads them as buttons or menus.
Photoshop revolves around editing pixels, unlike Adobe Illustrator which uses vectors. When an image is rendered into Photoshop, it is compiled by millions of single-colored pixels. At its core, Photoshop works by manipulating each individual pixel. Pixels are manipulated according to whichever tool is being used. In the case of other tools, such as Blending Modes, the pixels are modulated according to their relations with other pixels. Individual colors are encoded by a 3-part scale: red values, green values, and blue values (RGB). Each value is measured on a scale of 0 to 255, with saturation increasing proportionate to number scale. A value of Red: 255 Green: 0 Blue: 0 will be rendered as pure red. All 3 values at 255 will be rendered as white, all values at 0 will be rendered as black, etc.
Photoshop can utilize the color models RGB, lab, CMYK, grayscale, binary bitmap, and duotone. Photoshop has the ability to read and write raster and vector image formats such as .EPS, .PNG, .GIF, .JPEG, and Fireworks. It also has several native file formats:
* The .PSD (Photoshop Document) 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. Photoshop's popularity means that the .PSD format is widely used, and it is supported to some extent by most competing software.
* The .PSB (Large Document Format) format is a newer version of .PSD designed for files over 2 gigabytes.
* The .PDD (PhotoDeluxe Document) format is a version of .PSD that only supports the features found in the discontinued PhotoDeluxe software.
CS3
Photoshop CS3 is marketed with three main components of improvement over previous versions: "Work more productively, Edit with unrivaled power, and composite with breakthrough tools."New features propagating productivity include streamlined interface, improved Camera Raw, better control over print options, enhanced PDF support, and better management with Adobe Bridge. Editing tools new to CS3 are the Clone Source palette and nondestructive Smart Filters, and other features such as the Brightness/Contrast adjustment and Vanishing Point module were enhanced. The Black and White adjustment option improves users control over manual grayscale conversions with a dialog box similar to that of Channel Mixer. Compositing is assisted with Photoshop's new Quick Selection and Refine Edge tools and improved image stitching technology.
CS3 Extended contains all features of CS3 plus tools for editing and importing some 3D graphics file formats, enhancing video, and comprehensive image analysis tools, utilizing MATLAB integration and DICOM file support.

New Features Of The New Adobe Photoshop CS3 Extended Edition:
Nondestructive editing
Edit nondestructively with new Smart Filters, which let you visualize different image effects, and Smart Objects, which let you scale, rotate, and warp raster and vector graphics all without altering the original pixel data.
Rich painting and drawing toolset
Create or modify images with a wide assortment of professional, fully customizable paint settings, artistic brushes, and drawing tools.
Advanced compositing
Create more accurate composites by automatically aligning multiple Adobe� Photoshop� layers or images based on similar content. The Auto-align Layers command quickly analyzes details and moves, rotates, or warps layers to align them perfectly, and the Auto-blend Layers command blends the color and shading to create a smooth, editable result.
3D compositing and texture editing
Easily render and incorporate rich 3D content into your 2D composites even edit existing textures on 3D models directly within Photoshop Extended and immediately see the results. Photoshop Extended supports common 3D interchange formats, including 3DS, OBJ, U3D, KMZ, and COLLADA, so you can import, view, and interact with most 3D models.
Movie Paint
Enhance video directly within Photoshop Extended. Now you can paint, add text, and clone over multiple frames of an imported video sequence.
2D and 3D measurement tools
Extract quantitative information from images with new measurement tools. Easily calibrate or set the scale of an image, and then use any of the Photoshop Extended selection tools to define and calculate distance, perimeter, area, and other measurements. Record data points in a measurement log and export data, including histogram data, to a spreadsheet for further analysis.
Faster, more flexible asset management with Adobe Bridge CS3
Organize and manage images more efficiently with next-generation Adobe Bridge CS3 software, which now delivers improved performance, a Filter panel for easier searching, the ability to group multiple images under a single thumbnail, the Loupe tool, offline image browsing, and more.
Better raw-image processing
Process raw images with increased speed and superior conversion quality using the Photoshop Camera Raw plug-in, which now adds support for JPEG and TIFF formats; new tools including Fill Light and Dust Busting; compatibility with Adobe Photoshop Lightroom software; and support for over 150 camera models.
Enhanced Vanishing Point with 3D support
Edit in perspective on multiple surfaces even those connected at angles other than 90 degrees with the enhanced Vanishing Point, which also lets you measure in perspective; wrap graphics, images, and text around multiple planes; and output 2D planes as 3D models.
Wide range of supported formats
Import and export an even greater range of file formats, including PSD, BMP, DICOM, Cineon, JPEG, JPEG2000, OpenEXR, PNG, Targa, and TIFF.
