  2. 2. Thomas Knoll Glen Knoll John Knoll :Origins
  3. 3. :Thomas Knoll, the PHD student, Glen Knoll was a college professor andJohn Knoll, a talented special effects whiz came up with a core idea ofPhotoshop between 1987 and 1988.In February of 1990, Adobe 1.0 was released. And now Photoshop istwenty one years old.
  4. 4. Photoshop 2.0 included the Path feature, which allowed users to trim around an object easily and to save that path for future use. ?What is Adobe Photoshop
  5. 5. The big story for Adobe Photoshop 3.0 waslayers : Is a graphics editing program developed and published by Adobe Systems Incorporated
  6. 6. Adjustment layers and macros werethe two most notable features ofPhotoshop 4.0. : Adobe Photoshop, and Adobe Photoshop is released in Adobe Photoshop Extended editions, with the Extended having extra 3D image creation, motion graphics editing, and advanced image analysis features. Adobe Photoshop Extended is included in all of Adobes Creative Suite offerings except Design Standard, which includes the Adobe Photoshop edition.
  7. 7. The two most important featuresreleased with 5.0 were editable typeand the ability to undo actions multipletimes in the “History” palette. : Adobe only supports Windows and Macintosh versions of Photoshop, but using Wine Photoshop CS4 can run on Linux.
  8. 8. The most important feature releasedwith 5.0 was Save For Web. : PSD (Photoshop Document) is Photoshops native format. PSD format is limited to a maximum height and width of 30,000 pixels. Photoshops primary strength is as a pixel-based image editor, unlike vector-based image editors/ Adobe Illustrator, CorelDraw, etc.
  9. 9. The layer styles panel made workingwith layers even easier in Photoshop 6.Vector shapes were also added in thisrelease.There was also a new custom shapespalette that allowed the user to drawusing vector shapes rather than justusing lines.Text could also now be typed directlyonto a picture, rather than being typedfirst into a text box.Multi-layer functions made their firstappearance with version 6.0.The Blending Options dialogue was alsointroduced6.0 separated the crop tool from themarquee tool. : Photoshop also enables the creation, incorporation, and manipulation of vector graphics through its Paths, Pen tools, Shape tools, Shape Layers, Type tools, Import command, and Smart object functions there by enabling us combine pixel-based and vector-based images in one Photoshop document
  10. 10. Version 7.0 introduced the healingbrush and text that was fully vector-based.It introduced a new file browser that letdesigners easily pore through folders tofind the graphics that they wanted.Files within a folder could be renamedusing Batch Rename.Workspaces could also be created andsaved, allowing you to save your filelocations and groups for future use.The brush palette featured achanges, including the new healingbrush tool, patch tool, and the ability tocreate custom brushes.Spell check and a find/replace featurerounded out the updates to the texttool. :A number of enhancements were alsoincluded for web use, including theaddition of rollover effects for imagesand a web gallery feature.7.0 was optimized for use with Mac OSX, virtually eliminating crashes in themiddle of working on large files. PSD file format can be exported to and from Adobe Illustrator, Adobe Premiere Pro, and After Effects
  11. 11. Photoshop CS was the first to employ the CDS (counterfeit deterrence system) which recognized and refused to allow duplication of paper currency. Scripting support for various web languages, including JavaScript, was also new to this release. Layer groups were introduced with this version. Improvements to the File Browser made images easier to work with, and the 16-bit and better large file support made CS much easier to work with. : Computer displays are made up from grids of small rectangular cells called pixels; the term comes from "picture elements". The picture is built up from these cells. The smaller and closer the cells are together, the better the quality (resolution) of the image, but the bigger the file needed to store the data.Pixels *DPI/ Dots per pixel/ dots=pixels * resolution
  12. 12. The layer styles panel made working withred eyeeven easier in is The layers removal tool Photoshop 6. Vector shapes were also added in this added. release. options and the ability Smudging There was also a new custom shapes to select multiple layers also paletteto the functionality of to draw added that allowed the user using vector shapes rather than just Photoshop. using lines. Point tool allowed The Vanishing Text could also now be typed directly users to edit images in onto a picture, rather than being typed perspective. first into a text box. Multi-layer functions made their first appearance with version 6.0. The Blending Options dialogue was also introduced 6.0 separated the crop tool from the marquee tool. : In computer graphics, a raster graphics image, or bitmap, is a data structure representing a generally rectangular grid of pixels, or points of color, viewable via a monitor, paper, or other display medium. Raster images are stored in image files with varying formatsPixel Based/Raster Images
  13. 13. A faster loading is enabled. Graphic optimization for mobile devices is also a new feature. CS3 shipped in Standard and Extended editions. Cloning became easier in CS3 with the birth of the Clone Source palette which increased the options available to the Clone Stamp tool in an easily accessible palette. : Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based on mathematical expressions, to represent images in computer graphics. "Vector", in this context, implies more than a straight line.Vector Based Images
  14. 14. The smoother pan and zoom is enabled. The Masks and Adjustments panel was added, making working with masks easier. The user interface was significantly simplified in CS4.Vector Versus Raster Images
