Photoshop 7.0

Adobe Photoshop is said to have been made in 1988 by two American brothers named Thomas Knoll and John Knoll. In 1989 Adobe System bought the program from the Knoll brothers and introduced it as Photoshop.

What is Photoshop?

In general, Adobe Photoshop is considered a software that is used for picture editing.  For instance if you have a photograph of any person and you don’t like his or her eye color, complexion , dress, hair style ,hair color, background etc. you can make necessary changes  in that photograph according to your choice or requirement using Photoshop. Of course, the uses of Adobe Photoshop are not limited to the editing of human pictures. In the current time period this software is vastly used by interior decorators and commercial and web designers.

This definition of Photoshop might be enough for a person who has very little or nothing to do with computer graphics. But, if you are a graphics designer yourself or intend to start a career as one and at the same time,  able to make clear distinction between Raster and Vector Graphics, you can’t satisfy yourself with this superficial  sort of definition of this highly useful image editor.

As Adobe Photoshop deals with the editing and composing of Raster images (images based on small colorful dots referred as pixels) and it has very little ability to edit or compose Vector images, videos and 3D graphics so it is often referred as Raster Graphics Editor. Using this software one can draw or edit an image (Raster Image) on multiple layers. Further, through Photoshop two or more than two images can be combined flawlessly that they give the impression of a single image. This method of combining two or more than two images is called Compositing or Alpha Compositing. Adobe Photoshop supports all major color models including RGB Color, CMYK Color, Grayscale, Bitmap and LAB Color. Images edited or composed by the use of Adobe Photoshop can be saved in various formats e.g. JPEG, PNG, GIF, BMP etc.

At the top of the main window of Photoshop 7.0 there can be seen a Menu Bar containing nine different  tabs named File, Edit , Image  , Layer,  Select, Filter,  View, Window and Help.  Each tab represents  a different menu. Each menu contains various options and each option is proved important and helpful in some way or the other whenever it comes to compose or edit any image in Photoshop.
