Working With Selection Tools
It’s simple to create complicated selections with the basic marquee and selection tools. Here are some basic keyboard shortcuts that can help you unlock some hidden power of selections by adding, subtracting and intersecting.
Add Selection:
Shortcut Key (Shift)
With any selection tool active (see below) hold down shift when creating new selections to add them to the current selection.
Subtract Selection:
Shortcut Key (Alt)
When using a selection tool, hold Alt to subtract any newly created selection from the existing one, creating holes in selections, or allowing you to edit out mistakes.
Intersect Selection:
Shortcut Key (Shift + Alt)
Combines two selections to pick what they have in common. With an existing selection, hold Shift and Alt, and draw a selection in your image. The pixels in common will be picked.
Load Selection:
Shortcut Key (Ctrl + Click Layer, Ctrl + Click Channel)
Holding Ctrl and clicking the thumbnail in a layer or channel will load the opaque pixels in said layer or channel. Load selection also works with Add, Subtract, and Intersect, allowing for incredibly precise selections.
Basic Selection Tools in Your Toolbox
Now that we’ve covered the hidden features of the selection tools, we can take a look at the various selection tools we find in our toolbox, and some of the uses therein.
Rectangular Marquee: Shortcut Key (M)
Use the rectangular marquee to draw the “marching ants” selection around any roughly square areas, and create new layers or masks with your new selection.Hold down
Shift and
Click + Drag to draw squares.
Also try: Add Selection, Subtract Selection, and Intersect Selection with this tool.
Elliptical Marquee:
Shortcut Key (Shift + M)
Picking the Elliptical Marquee will allow you to draw selections around your circular and elliptical shaped areas you want to isolate or mask.Hold down
Shift and
Click + Drag to draw perfect circles.
Also try: Add Selection, Subtract Selection, and Intersect Selection with this tool.
Lasso: Shortcut Key (L)
Select the lasso to draw freeform lines around your object, in any shape you can mouse or draw with your stylus. Once selected, copy to a new layer or use masks to block off the unwanted areas in your layer.Hold down
Alt and release the mouse button to quickly switch to the Polygonal Lasso.
Also try: Add Selection, Subtract Selection, and Intersect Selection with this tool.
Polygonal Lasso:
Shortcut Key (Shift + L)
The Polygonal Lasso allows you to draw straight lines between points you create with clicks of your mouse. An excellent way to draw precise angular selections quickly, without the pain of clicking and dragging.Hold down
Alt and release the mouse button to quickly switch to the regular Lasso Tool.
Also try: Add Selection, Subtract Selection, and Intersect Selection with this tool.
Magnetic Lasso:
Shortcut Key (Shift + L)
The Magnetic Lasso uses Photoshop’s edge detect to snap to the edges of objects. In cases where the edges are clear to the program, this is a decent way to isolate an object. Often, it offers a rough, somewhat poor selection.Hold down Alt to quickly switch to either the regular lasso or the Polygonal Lasso in this mode.
Also try: Add Selection, Subtract Selection, and Intersect Selection with this tool.
Magic Wand:
Shortcut Key (W)
Working similar to the Bucket Fill, the magic wand creates a selection of touching, adjacent similar colors.In the options panel, deselect “
contiguous” to find all similar colors in the entire document, regardless of whether they touch or not.
Also try: Add Selection, Subtract Selection, and Intersect Selection with this tool.
Quick Selection Tool:
Shortcut Key (Shift + W)
Another rough edge-detecting tool, Quick Selection will provide a basic outline when the program can easily find edges. Depending on how you “paint” with Quick Selection, Photoshop may find more or less of your object.
Also try: Add Selection, Subtract Selection, and Intersect Selection with this tool.
Combinations of these tools and techniques already offer users a wide range of easy, precise, and serviceable ways to remove backgrounds and isolate objects. However, Photoshop still has perhaps hundreds of ways to remove backgrounds—many of which we’ll cover, starting in part 2 of “50+ Ways to Remove Image Backgrounds.”
