UNDERSTANDING FILE SIZE

Because Photoshop requires about five times the file size of an image to work comfortably, you may need to consider how many files you have open at the one time and what affects file size. Several factors can affect the size of an image, including its file format, its actual dimensions in pixels, the number of colours that are used in the image and its resolution.

Understanding File Format

When working on images in Photoshop, you will need to consider different file formats, based on what your images are and what you plan to do with them. For example, you may want to place your images on a website or email them, in which case they need to have a small file size so that they load quickly. This page describes four file formats and how and when they should be used.

Creating A New Image

There are various options that you can set as you create a new image in Photoshop. You can select the appropriate resolution, colour mode and background colour for the image. You can also specify either a custom size for your image or choose from one of the numerous preset sizes that were created by Photoshop.

About The Toolbox

ABOUT THE TOOLBOX

Photoshop’s tools are kept in a palette called the Toolbox. They can be selected by either clicking on them or pressing the relevant shortcut key. Although 25 tools are visible, there are many more grouped behind other tools. Grouped tools have a black triangle in their bottom, right corner. To access hidden tools, click on a tool to display the options in the Options bar.

Working With The Palette Dock

The palette dock displays the available palettes within Photoshop. It is possible to alter the display of the palette dock to either show more or less of the palettes, enabling you to conserve workspace if and when required. This ability to collapse palettes to icons is a new feature to this version of Photoshop. By clicking on any of the icons, you display the palette contents.

The Photoshop CS3 Workspace

The default Photoshop CS3 workspace is grey and comprises several components – the Menu bar, Options bar, Tool palette, Document window, Palette icons and three palette groups:

Navigator group, Colour group and the Layers group. Your workspace may look different to the example shown below as you can open, close and move the components around on the screen.
