Complete Q’s and A’s
Quick Selection Tool - -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 - -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? - -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 - -Lets you select ovals or perfect circles.
- What happens when making selections with the Spacebar? - -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 - -Press Z to activate the zoom tool.
- Fit on Screen Shortcut - -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 - -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? - -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? - -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? - -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? - -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.
- What does anti-aliasing mean? - -Anti-aliasing smooths the jagged edges
of a selection by softening the color transition between edge pixels and
background pixels. Since only the edge pixels change, no detail is lost. Anti-
aliasing is useful when cutting, copying, and pasting selections to create
composite images.
To use anti-aliasing, select a lasso tool, or the Elliptical Marquee or Magic
Wand tool, and select Anti-alias in the options bar. To apply anti-aliasing, you
must select the option before making the selection. Once a selection is
made, you cannot add anti-aliasing to it.
- What does feathering mean? - -Feathering blurs edges by building a
transition boundary between the selection and its surrounding pixels. This
blurring can cause some loss of detail at the edge of the selection.
You can define feathering for the marquee and lasso tools as you use them,
or you can add feathering to an existing selection.
To define a feathered edge for a selection tool, select any of the lasso or
marquee tools. Enter a Feather value in the options bar. This value defines
the width of the feathered edge and can range from 1 to 250 pixels.
