Setting up your document correctly from the start will make your job much easier as you work through your project. This will require some advanced planning. For example, if your final output will be a brochure, you may need to set up your document to be horizontal and double-sided.

To create a new document, click File > New. This will open the Document Setup dialog box (Fig. 2).

Here you will be able to name your file, set up the correct page size, and orientation for your document. Options include, but are not limited to:

Page Size and Orientation Change the page size by typing in new values for width and height. Page size represents the final size you want after bleeds or trimming other marks outside the page. In the Preset dropdown menu you can find such common sizes as letter, legal, tabloid, etc. Typing in exact values for Height and Width gives you more control over the size and orientation of your page. Resolution Resolution is a number of pixels on a printed area of an image. The higher the resolution, the more pixels there are on the page, the better is the quality of the image. However, high resolution increases the size of the file. The standard recommended resolution for printed images is 150-300, for Web images it is 72. Color Mode Choose a color mode that will best fit your project. For example, when making a graphic for a web site, choose RGB. When making an image for print, choose CMYK. Background Contents Choose the background: white, color, or transparent. When you have entered all of your document settings, click OK.

OPENING AN IMAGE FROM A DISK If the image you have is saved on a disk, select File > Open, and then navigate to the disk drive where your image is saved. Choose the image file and click Open. At this point, you may want to save your image under a different name so that you can always have the original to fall back on in case of a mistake. To save you r file, select File > Save As and type in the new name of the file in the dialogue box. Now you should be ready to go.

This is the layout of Adobe Photoshop interface.

Menu Bar If you look at the top of the screen you will see the Menu bar which contains all the main functions of Photoshop, such as File, Edit, Image, Layer, Select, Filter, View, Window, and Help.

Tool Bar Most of the major tools are located in the Tool bar for easy access.

The Image The image will appear in its own window once you open a file.

Image Name The name of any image that you open will be at the top of the image window as shown above.

Palettes Palettes contain functions that help you monitor and modify images. By default, palettes are stacked together in groups. These are the palettes that are usually visible: Color, Adjustments, and Layers. If none of the palettes are visible, go to Window in the Menu bar and choose palettes you need to work with.

Below is the description of the most commonly used palettes in Adobe Photoshop CS4. Palettes used for more advanced image editing will be covered in the Adobe Photoshop CS4 Tutorial -Intermediate.

COLOR, SWATCHES, STYLE The Color palette (Fig. 2) displays the current foreground and background colors and RGB values for these colors. You can use the sliders to change the foreground and background colors in different color modes. You can also choose a color from the spectrum of colors displayed in the color ramp at the bottom of the palette.

In the Swatches palette (Fig. 3) you can choose a foreground or background color or add a

The Styles palette (Fig. 4) allows you to view, select, and apply preset layer styles. By default, a preset style replaces the current layer style. You can use the styles in the palette or add your own using the Create New Style icon.

The History palette (Fig. 5) stores and displays each action performed allowing you jump to any recent stage of the image alteration. The alterations should be created during the current working session; after saving or closing the document the History palette clears all the contents. Each time you apply a change to an image, the new state of that image is added to the palette. The History palette can store up to 20 stages. However, you can always go back to the first stage, for example opening the document. It is important to know that once you click on any of the previous stages, all the changes that were made after it will be lost.

Adjustment layers give you the ability to apply an effect to a group of layers in Photoshop, and then you can edit that effect later, while preserving the original layers.

Layers let you organize your work into distinct levels that can be edited and viewed as individual units. Every Photoshop CS4 document contains at least one layer. Creating multiple layers lets you easily control how your artwork is printed, displayed, and edited.
