This document provides an overview of Photoshop, including its history, features, and customer market. Photoshop was created in 1988 by brothers Thomas and John Knoll and was acquired by Adobe Systems. It has since become the industry standard image editing software. Photoshop allows for powerful image editing through features like layers and masks. It also supports plugins that extend its functionality. While aimed at professionals, Adobe also offers a more casual version called Photoshop Elements for hobbyists.

3. I. Introduction To Photoshop
• Adobe Photoshop is a graphics editing program developed and
published by Adobe Systems and is one of the most powerful image
modification programs on the market today.
• In 1987, Thomas Knoll, a PhD student at the University of Michigan,
began writing a program on his Macintosh Plus to display grayscale
images on a monochrome display.
• Thomas took a six month break from his studies in 1988 to
collaborate with his brother on the program, which had been
renamed ImagePro.

4. I. Introduction To Photoshop
(Cntd)• Later that year, Thomas renamed his program Photoshop and
worked out a short-term deal with scanner manufacturer
Barneyscan to distribute copies of the program with a slide scanner;
a "total of about 200 copies of Photoshop were shipped" this way.
• During this time, John traveled to Silicon Valley and gave a
demonstration of the program to engineers at Apple Computer Inc.
and Russell Brown, art director at Adobe.
• Both showings were successful, and Adobe decided to purchase the
license to distribute in September 1988. While John worked on plug-
ins in California, Thomas remained in Ann Arbor writing program
code. Photoshop 1.0 was released in 1990 for Macintosh
exclusively.

5. I. Introduction To Photoshop
(Cntd)• Photoshop's popularity, combined with its high retail price, makes
Photoshop's piracy rate relatively high.
• It is so dominant that when we notice an image has been altered,
we say it has been “Photoshopped.”
• It is the current market leader for commercial bitmap and image
manipulation software, 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 the
PC.

6. II. Release History
• The Adobe Photoshop was created by independent creators
Thomas and John Knoll in the summer of 1988. The license to
distribute the program was purchased by Adobe Systems in
September 1988.
1. Early versions

10. III. Features
Photoshop has
strong ties with
other Adobe
software for
media editing,
animation, and
authoring.

11. III. Features
The .PSD (Photoshop Document), Photoshop's native
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.

12. III. Features
Photoshop is a pixel-based image
editor, unlike Adobe Illustrator, which
is a vector-based image editor.

13. III. Features
Photoshop has the ability to read
and write raster and vector image
formats such as .EPS, .PNG,
.GIF, .JPEG, and Fireworks.

14. IV. Photoshop CS3 & CS4
1. Introduction
• Photoshop has strong ties with other Adobe software for media
editing, animation, and authoring. The .PSD (Photoshop Document),
Photoshop's native format, stores an image with support for most
imaging options available in Photoshop.
• Photoshop's popularity means that the .PSD format is widely used,
and it is supported to some extent by most competing software.
• The .PSD file format can be exported to and from Adobe Illustrator,
Adobe Premiere Pro, and After Effects, 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.
Photoshop is a pixel-based image editor, unlike Adobe Illustrator,
which is a vector-based image editor.

15. 2. Photoshop CS3
• Photoshop CS3 is marketed with three main
components of improvement over previous
versions: Work more productively, edit with
unrivalled 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.

16. 3. Photoshop CS4
• Photoshop's popularity means that the .PSD format
is widely used, and it is supported to some extent
by most competing software.
• The .PSD file format can be exported to and from
Adobe Illustrator, Adobe Premiere Pro, and After
Effects, 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.
• Photoshop is a pixel-based image editor, unlike
Adobe Illustrator, which is a vector-based image
editor.

17. V. Plug-ins & Customer Market
• Photoshop plug-ins are add-on programs aimed at providing
additional image effects or performing tasks that are
impossible or hard to fulfill using Adobe Photoshop alone.
• Plug-ins can be opened from within Photoshop and several
other image editing programs and act like mini-editors that
modify the image.

20. V. Plug-ins & Customer Market
4. Customer Market
• While Photoshop is the industry standard image editing
program for professional raster graphics and other digital art,
its relatively high suggested retail price has led to a number of
competing graphics tools, such as GIMP and Paint.NET, being
made available at lower prices or as freeware for the amateur
market.
• To compete in this market, and to counter unusually high
rates of piracy of its high end products, the company
introduced a consumer-oriented version of Photoshop as
Adobe Photoshop Elements.

21. V. Plug-ins & Customer Market
4. Customer Market (Contd.)
• A more user-friendly interface and new tools such as the
"red-eye" reduction brush were aimed firmly at the more
casual image editor.
• Many professional features were omitted.
• Removing CMYK functionality, for example, made Elements
unsuitable for commercial prepress work.

22. VI. Conclusion
• Photoshop is the current market leader for commercial
bitmap and image manipulation software, and is the flagship
product of Adobe Systems.
• Photoshop has strong ties with other Adobe software for
media editing, animation, and authoring.
• Photoshop functionality can be extended by add-on programs
called Photoshop plugins which act like mini-editors that
modify the image.
• A more user-friendly interface and new tools such as the
"red-eye" reduction brush were aimed firmly at the more
casual image editor.
