Determining color similarity
When using the Similarity entry box, enter a value that you feel closely
reflects the range of colors you wish to select. To help determine the color
similarity range, move the Magic Wand over target pixels in the image and
notice the RGB color values displayed on the Status bar. Below is a
guideline on what to expect when choosing particular color ranges, (you
can only select a color range between 0 and 255):
• A value of 0 selects neighboring pixels with exactly the same color
value, such as all white.
• A value of 255 selects pixels of all colors, thereby selecting the entire
image.
• A value of 50 selects neighboring pixels that have values that differ
from the pixel you click on by 50. For example, if you click on a pixel
with values R25, G60, B190, neighboring pixels with values between
R0, G10, B140, and R75, G110, B240 are selected.
Adding to or subtracting from a selection area
Once you’ve created a selection area, you may discover that you left out a
portion of the image you wanted to include. To add to an already existing
selection area, press the [
A
] key and use the selection tool as you would to
create a new selection area. The area you select is added to the rest of the
selection area. To subtract from a selection area, press the [
S
] key and
select the part of the selection area you want to remove.
