The Quick Selection tool has two variations:
The Quick Selection tool was added to Photoshop in CS3 and became the
default (and favourite) selection tool, pushing the trusty Magic Wand
tool into the background...or, more precisely, underneath it in the
Toolbox. The Quick Selection tool is brush-like, letting you "paint"
your selection on the image. It's not a replacement for the other
selection tools; sometimes it's best used as the final step in
fine-tuning a rough selection. The keyboard shortcut for the Quick
Selection tool is W (formerly used for the Magic Wand tool).
The Quick Selection tool has a brush tip that you drag around inside the area you want to select. The tool will pick up similarly coloured pixels and can detect edges.
1. Select the Quick Selection tool (
) in the toolbox or hit Shift W to switch between the Magic Wand and the Quick Selection tools.
2. In the tool options bar, click the Brushes tab to temporarily open the Brushes palette. Set the Brush Size diameter and the hardness of the brush. You may find there is a bit of trial and error involved while you find the correct sized brush.
If you are using more than one layer you could choose the Sample All Layers option to sample from all visible layers, not just the selected one. In this example there is only one layer in the image so this is not an issue.
3. Click on part of the blurred green background, and gently drag the pointer. You’ll see the Quick selection tool very accurately selects a chunk of background.
Continue to drag around the flowers. If you accidentally select a flower, hold down the Alt/Option key and paint to deselect. If it happens repeatedly, try reducing the size of your Quick Selection brush.
4. Continue to drag around the flowers until you complete the selection. You’ll find that this tool is quite intuitive and that you only need to paint small areas in order to select large chunks.
Ok that’s the selection made, but we’re not finished with this tool yet. Sometimes selections have very jaggy edges, but with the Quick Selection tool you can refine your selection.
5. In the tool options bar, click on the Refine button, which opens the following dialog box;
I won’t go through each of the options, suffice to say that there is plenty of sliders for you to play with and explore. For this example I increased the smoothness, which helps removes some of the jagged edges.
6. Finally I hit Delete to remove the background (remember we had actually selected the background and not the flowers). I can now easily add a different background.

Quick Selection Tool Options
- Selection Options
The three selection options are New Selection, Add to Selection, and Subtract from Selection. If no selections are present in the image, the New Selection option is automatically in effect. Once you release the mouse button, it will switch to the Add to Selection option automatically. If you find you've painted "outside the lines", you can switch to Subtract from Selection to remove the parts of the selection you don't want.
- Brush Picker
This option lets you select the diameter and hardness of the brush tip. You can also change the brush size while you're selecting by pressing the left square bracket ([) to decrease the diameter or the right square bracket (]) to increase it. A smaller brush size has a lower tolerance and will be more sensitive to detecting edges.
- Sample All Layers
If the area you want to select is divided between several layers, enabling this option will look at all the layers instead of just the current layer.
- Auto-Enhance
This option adds some smoothing as you're using the Quick Selection tool.

Quick Selection Tool Summary
- The Quick Selection tool lets you "paint" on a selection by dragging a brush over the image.
- This tool has three Selection Options as well as the Brush Picker, Sample All Layers, and Auto-Enhance options.
- The Magic Wand tool makes selections by comparing the RGB value of the pixel clicked on with other pixels in the image and includes other pixels within the prescribed colour range in the selection.
- This tool has several options: the four Selection Options, Tolerance, Anti-alias, Contiguous, and Use All Layers.
- The Tolerance option determines how closely the RGB value of other pixels must be to the target pixel before they will be included in the selection.
- The Contiguous option, when enabled, will cause only adjacent pixels to be considered for the selection. When it is disabled, the entire image is considered.
