Introduction to Photoshop

Photoshop is a photo-editing software. It is a popular image changing software package. It was developed in 1987 by the American brothers Thomas and John Knoll. There are two types of graphic software – Vector Graphic and Raster Graphic. This software provides many image editing features for raster (pixel-based) images as well as vector graphics. In technical language, Photoshop is a RASTER graphic software, which means it is used to edit the raster graphics.

RASTER is a combination of pixels. A group of pixels forms a graphic called Raster Graphics. There are various forms of formats of Raster Graphics –

  • JPEG – Joint Photographic Experts Group
  • PNG – Portable Network Graphics
  • GIF – Graphics Interchange Format

Photoshop is a tool for designers, web developers, graphic artists, photographers, and creative professionals. It is widely used in industries. Web Designer uses photoshop first to make a logo for website. Application Designer also uses photoshop first to create User Interface for his application. Even, 3D game developer also uses photoshop to create a digital painting of its character in game. One can also develop Matte Painting (which is unusual, as the unreal type of scenes) scenes using these tools.

Workspace and Interface :
Opening photoshop on laptop, welcome screen will appear. To work on any photo select it. On the left, photoshop tools will appear and on right, layer panel and color panel appear. The working area in center is known as canvas.
Sometimes, we don’t get a toolbar or layer panel on screen. To resolve this problem, Go to windows written on upper part of screen and then to workspace and then reset essentials. The toolbar or layer panel or anything if goes missing on screen can be resolved by this problem.

When we open workspace, there comes several options like 3D for a 3D designer, Graphics and Web for graphics and web designing, Motion for animations, paintings and photography.

How to make a new workspace ?

  • Go to workspace.
