year, they released a version that could be used on IRIX and Solaris, operating systems Notes
used mainly by programmers. Adobe eventually released 10 versions of the program
using the Photoshop name, ending with version 7.0.1, which was released in 2002.
Subsequent versions of the program were renamed Photoshop CS and were bundled with
other products in Adobe’s Creative Suite.
Photoshop CS
The first version of Photoshop CS was released in 2003 and came bundled with Bridge,
Illustrator, InDesign and Version Cue; the premium edition also included Acrobat,
Dreamweaver and GoLive. Photoshop CS2 was released in 2005 and CS3 came out in 2007.
CS3 included the addition of three Macromedia programs, Dreamweaver, Flash and
Fireworks.CS4 was released in 2008 and contained several more media programs. All of
the programs in the CS bundle are designed to be used as cross platforms. For example, a
document created in Photoshop can be exported to Flash for animation and imported into
a webpage using Dreamweaver.
Photoshop Elements
Photoshop Elements is a budget version of Photoshop; it can perform many of the same
functions as the original version but at a much lower cost. Elements was designed primarily
for photograph editing, but it does not have all of the exportation functions found in the
CS line of products. Photoshop Elements was first introduced in 2001 and the application
is regularly upgraded with new features.
Questions:

1. Who was the designer of Photoshop? And in which year it was used for first time.
2. Explain the Photoshop product and its features.

3.5 Summary

z When you instruct PhotoShop to change the size of an image, it merely spreads out or
scrunches the image pixels.
z To keep resolution the same while stretching, PhotoShop must add new pixels to the
image and decide what color they should be.
z Changing image size actually changes the color information in the image, so you might
want to save a copy before resizing an image forty times to decide how you like it.

z Every time PhotoShop changes the image, it removes or adds pixels, slightly lowering
image quality.
z Whereas resizing reduces or enlarges the entire image and everything in it, cropping does
not alter the size of the image content at all. The following steps will demonstrate how to
crop an image in Photoshop
z To practice with the crop tool, open an image in Photoshop; click “File>Open,” browse for
the image on your computer, and click “Open.” The RGB color model is dependent upon
the hypothesis that every visible color could be made utilizing the primary additive
colors red, green and blue.
z One of the most prominent color modes in Photoshop and the other graphic softwares is
the RGB color mode.
z All the colors have a value of 255 each and hence changing the value from 0 to 255 for each
color produces 16.8 million colors.
