First, there is the marquee or selection tool. It is used when selecting your image within a rectangular or circular frame. If you hold down the black arrow on this button, you will see the various options for the Marquee tool, including the circle marquee.
Next we have the magic wand. This is another selection tool that is used often in image editing. You select your image according to a percentage or tolerance level. If you set a 30 percent tolerance level for the image, you may only get a small selection of the entire image. Whereas, if you select 75 percent, you will have a greater chance of capturing more of the image.
The Blur tool is used to blur images in order to get a feathered or cloudy special effect.
The Paint Bucket tool is often used to add a color to an entire background or a selected area.
And last, but definitely not least, are the Color Swatches. You have to toggle back and forth between the Foreground and Background color to set the color for both. Simply click on either the foreground or background color, and a swatch palette will open up allowing you to pick a color for both your foreground and background color, for your canvas. This does not represent all of the colors you have at your disposal – that is what the Color Palette is for.
