The noticeable change that you might first found in Photoshop CS3 interface is the single column toolbox, even so you can switch to traditional two column tool box by click at small arrow button ( ) at top left corner of the toolbox. I’ve use two column CS3 toolbox to demonstrate above because it’s easier when compare the tool placement with earlier version of Photoshop. You can see the full picture of new single-column CS3 toolbox by click at its thumbnail on the right.The two column toolbox in Photoshop CS3 is quite similar with the Photoshop CS2. It’s add two more new tool which is Quick Selection tool, add to Magic Wand’s place, and Count Tool, in Eyedropper Tool block. And also, the pen tool and path selection tool location are switch.
To optimize the space for the width of single-column toolbox, the quick-mask button and the screen mode button are also change. The quick-mask button is turn from two left and right toggle button to one On/Off button. The Screen mode in Photoshop CS3 also have new screen mode screen mode (Maximized Screen Mode) that you can easily select though pop-up menu. With this new screen mode you can have toolbar while working in Full Screen mode which is impossible for earlier version of photoshop. |
Note: The tool’s keyboard short-cuts are indicated in (). You can press shift + tool shortcut to toggle to hidden tool.

Retouching Tools
Spot Healing Brush Tool 
and Healing Brush Tool 
The Healing Brush tool (J) lets you correct imperfections, causing them to disappear into the surrounding image. Like the cloning tools, you use the Healing Brush tool to paint with sampled pixels from an image or pattern. However, the Healing Brush tool also matches the texture, lighting, transparency, and shading of the sampled pixels to the source pixels. As a result, the repaired pixels blend seamlessly into the rest of the image.
The Spot Healing Brush Tool (J) is different from the Healing Brush Tool in that it does not require you to make a selection or define a source point before using it. You can select a blending mode for the healing, and choose between proximity match or create texture. You can also sample all layers which allows you to use the spot healing tool on a new layer for non-destructive editing.
Patch Tool 
and Red Eye Tool 
The Patch tool (J) lets you repair a selected area with pixels from another area or a pattern. Like the Healing Brush tool, the Patch tool matches the texture, lighting, and shading of the sampled pixels to the source pixels. You can also use the Patch tool to clone isolated areas of an image.

Eraser Tool 
, Background Eraser 
and Magic Eraser Tool 
The Eraser tool(E) delete pixels in the image as you drag through them. If you’re working in the background or in a layer with transparency locked, the pixels change to the background color. Otherwise, the pixels are erased to transparency. You can also use the eraser to return the affected area to a state selected in the History palette.
The Background Eraser tool(E) allows you to erase the background while maintaining the edges of an object in the foreground. By specifying different sampling and tolerance options, you can control the range of the transparency and the sharpness of the boundaries.
The background eraser samples the color in the center of the brush, also called the hot spot, and deletes that color wherever it appears inside the brush. It also performs color extraction at the edges of any foreground objects, so that color halos are not visible if the foreground object is later pasted into another image. And please note that, the background eraser overrides the lock transparency setting of a layer.
When you click in a layer with the Magic Eraser tool(E), the tool automatically changes all similar pixels. If you’re working in the background, or in a layer with locked transparency, the pixels change to the background color; otherwise, the pixels are erased to transparency. You can choose to erase contiguous pixels only or all similar pixels on the current layer.

Dodge Tool 
and Burn Tool 
Dodge Tool (O) and Burn Tool (O) are use to lighten or darken areas of the image, the name are based on a traditional photographer’s technique. Photographers hold back light to lighten an area on the print (dodging) or increase the exposure to darken areas on a print (burning).

Depending on how you use the type tools, you can enter point type or paragraph type. Point type is useful for entering a single word. You can create point type by click in the image to set an insertion point for the type. The paragraph type is useful for entering and formatting the type as one or more paragraphs. You can create paragraph type by drag the tool to define a bounding box for the type.
Horizontal Type Mask Tool 
and Vertical Type Mask Tool 
Horizontal Type Mask tool (T) or Vertical Type Mask tool (T) let you create a selection in the shape of the type. Type selections appear on the active layer, and can be moved, copied, filled, or stroked just like any other selection. For more information about working with selections

Pen Tool 
and Freeform Pen Tool 
The Pen tool (P) lets you create straight lines and smooth flowing curves as new Path

, key and click at the point you want to convert.
Shape Tool (U) 
Photoshop provides six Shape Tools that enable you to draw geometric and predefined shapes. By default, the shapes are separated off into independent Shape layers , which are a mix of objects and pixels. The vector-based outlines of the shapes print at the maximum resolution of your printer, but the interiors may consist of solid colors, gradients, or pixel-based patterns and images.
Other than shape layer, you can also use Shape tool to create Path or Fill pixels by select Path button or Fill Pixels Button at the tool option bar. (See also Photoshop Path, Shape Layer and Fill Pixels)
Like making a selection you can also combine, delete or intersect and moreover exclude overlap area of new shape with current shape by select the operation you like to in tool option bar or holding down some keyboard keys.
