Creating the right working environment is very important even in Photoshop 6, which allows you to move your palettes out of the way. To work effectively you still need to be able to see as much of your image as possible without being hindered by palettes. Using the Screen Mode will allow you to open up your image fully making it much easier to work on and view.
Shown above is the standard Photoshop window. On the bottom of the tool box is the Screen Mode settings, the left button is the default window which places your image in a frame.
A good starting point is to enlarge your image using the Zoom tool. Double clicking on the zoom tool will open your image to fit on the screen or click on the 'Fit On Screen' button found on the options bar.
Click on the center button of your tool box will displays the Full Screen window, this removes the frame from your image and puts it onto a 50% gray background. Try using the shortcut key F to toggle through these options.
The right button displays a Full Screen window with a black background. The shortcut key F can be used again to get to this mode.
Pressing the Tab key on your keyboard will hide all the tools and palettes leaving you with just your image, making this is ideal for viewing. Press the Tab key again and the tools and palettes will return.
Try using the shortcut key F to take you through the screen modes you'll find it much quicker and easier.
