Selections:
Adding/Subtracting:
With any selection tool, SHIFT (+) while selecting will add to the selection
(you must have made a selection, no matter how bad it is, at first in
order to add to it or subtract from it). OPTION (-) while selecting will
subtract from a selected area.
Inverse the Selection
Under the Select Menu: Inverse or command-shift-I
This will select the opposite of what you have selected. Remember when
I selected the white area around the flower during our lab time, then
I went to Select: Inverse--this selected just the flower.
Tools and Options:
Marquee tool:
Selects a rectangle or ellipse
Hold down SHIFT to constrain the proportions (ie. to make a perfect circle
or square selection).
Feathering will create a soft edge near the border of the selection (it
will look fuzzy or blurry if you select an image with feathering and then
move it somewhere else).
While you are drawing the selection, hold down SPACE BAR to move the selected
area around on the screen--the trick is to NOT let go of the mouse until
you are completely finished with the selection.
Magic Wand:
Selects an area by pixel data (color).
Tolerance: tells the computer how many "like" pixels to select.
A higher tolerance means a larger selected area.
Lasso:
Selects an area by freehand drawing
Magic Lasso: tries to "find the edges" of the area you are selecting.
This one can get you into a big mess of "selected areas". If
you get lost, double-click and then deselect. Start again. In order to
complete the selection, you have to close the path (find the O where you
started the selection). If the magnetic lasso isn't "finding the
edges" for you, you can force it to place down anchor points by clicking
the mouse.
RGB
If you scanned in black/white or grayscale, make sure the image is in
RGB mode in order to add any color to it. Use Image: Mode: RGB
In the Images Menu, see Adjustments for methods of colorizing
an image. In class we looked at Invert (command + I) and Hue/Saturation
(command + U).
Key Commands we learned in class:
Command = Apple (they're the same key)
On a PC Command or Apple = "Control"
On a PC Option = "Alt"
Space Bar: yields the Hand tool, which enables us to move
the image around within the file. It doesn't actually MOVE the image (that's
the move tool), but it changes our view.
Space Bar + Command = Zoom In
Space Bar + Command + Option = Zoom Out
Shift + Selection Tool = Add to the selection
Option + Selection Tool = Subtract from the selection
Option + Move Tool = Make a duplicate (then look in your
layer palette)
Command + H = Hide the selection edges
Command + D = Deselect the selection
Command + S = Save
With a selection in progress, + Space Bar = Move the selection
Option + Drag a selection = drag from the center point
HOMEWORK

In class we will complete a tutorial on the pen
tool.
