TESTED.
⩥ Cutting Selected Pixels. Ans: 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?. Ans: 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?. Ans: 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?. Ans:
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?. Ans: 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?. Ans: 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?. Ans: 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.
To define a feathered edge for an existing selection, choose Select >
Modify > Feather. Enter a value for the Feather Radius, and click OK.
⩥ What does the Refine Edge option do?. Ans: To use the Refine Edge
option, first make a selection, and then click Refine Edge in the options
bar to open its dialog box. You can use the Refine Edge option to smooth
the outline, feather it, or contract or expand it.
⩥ Lasso Tool Shortcut. Ans: Press L
