far enough so that a few pixels appear,
and then place the white or black point
at the corresponding area that contains
a cluster of pixels in
close proximity.
Watch Points
The Watch Points section of the Photo
Info Palette displays the position and
color of the pixel under the mouse
pointer.
Within the Watch Points section,
you are provided with the following
controls:
Create Watch Point Button
By clicking on this button, you can add
up to four Watch Points to your image.
When you click on this button, the
mouse cursor will change and enable
you to place a Watch Point directly on
the image. A Watch Point icon will be
placed on the image displaying where
you placed a Watch Point and an
entry will be added to the Watch Point
section that continually monitors the
colors of the selected pixel.
You can move and reposition any of
the Watch Points placed on your image
by simply clicking and dragging that
point. You can delete the Watch Point
by clicking on the
button within the
Watch Point section of the Photo Info
Palette that corresponds to the Watch
Point you wish to remove.
Color Model
This pull-down Menu enables you to
select the color model used to describe
the colors within the Watch Point
section. You can choose between the
RGB and HSB color models.
Sample Size
Use this option to change the number
of pixels which are used in sampling for
both the current color under the mouse
pointer as well as for each of the Watch
Points.
The Point option samples only a
single pixel. This is helpful if you want
to be very precise when selecting a
color and are able to target a pixel of a
specific color.
The 3 × 3 average option samples a
total of nine pixels in a grid of three
pixels by three pixels and averages the
colors of each pixel before displaying
the result. Since areas within a photo-
graph are generally made up of small
variations of color, selecting this option
provides a more accurate rendition of
the color of the targeted area.
The 5 × 5 average option samples a
total of twenty-five pixels in a grid of
five pixels by five pixels and averages
the colors of each pixel before display-
ing the result. This option is recom-
mended for higher resolution images.
