Quick Selection Tool - (answer)One of the easiest ways to make a selection. You simply paint an
area of an image, and the tool automatically finds the edges. You can add or subtract areas of the
selection until you have exactly the area you want.
Auto Enhance - (answer)When Auto Enhance is selected, the Quick Selection tool creates better
quality selections, with edges that are truer to the object. The selection process is a little slower
than using the Quick Selection tool without Auto Enhance, but the results are superior.
How do you deliberately deselect a selection? - (answer)You can choose Select > Deselect, press
Ctrl+D (Windows) or Command+D (Mac OS), or click outside the selection with any selection
tool to start a different selection.
Elliptical Marquee tool - (answer)Lets you select ovals or perfect circles.
What happens when making selections with the Spacebar? - (answer)Use the spacebar as needed
to reposition your selections. By holding down the mouse button, press the spacebar and
continue to drag the selection. Instead of resizing the selection, now you're moving it.
,Zoom Tool Shortcut - (answer)Press Z to activate the zoom tool.
Fit on Screen Shortcut - (answer)You can see all of the objects in the image window by pressing
Command+0 or Crtl+0. You can also double-click the hand tool icon.
Cutting Selected Pixels - (answer)During an image selection, and with the Elliptical Marquee
tool (for example) selected in the Tools panel, press Ctrl (Windows) or Command (Mac OS), and
move the pointer within the selection.
The pointer icon now includes a pair of scissors to indicate that the selection will be cut from its
current location.
What happens with a selection when using the arrow keys? - (answer)You can make minor
adjustments to the position of selected pixels by using the arrow keys. You can nudge the
selection in increments of either one pixel or ten pixels.
When you hold down the Shift key, the selection moves ten pixels every time you press an arrow
key.
, How to hide the edges of a selection temporarily? - (answer)You can hide the edges of a
selection temporarily without actually deselecting, and then display the selection border once
you've completed the adjustments.
Choose View > Show > Selection Edges or View > Extras.
You can also press Command+H or Control+H
Either command hides the selection border around the plate of shells.
What type of selections is the Magic Wand tool most useful for? - (answer)The Magic Wand tool
selects all the pixels of a particular color or color range. It's most useful for selecting an area of
similar colors surrounded by areas of very different colors.
If a multicolored area that you want to select is set against a background of a different color, it
can be much easier to select the background than the area itself.
What does the tolerance option do to the Magic Wand tool? - (answer)The Tolerance option sets
the sensitivity of the Magic Wand tool. This value limits or extends the range of pixel similarity.
The default tolerance value of 32 selects the color you click plus 32 lighter and 32 darker tones
of that color. You may need to adjust the tolerance level up or down depending on the color
ranges and variations in the image.
