Getting Information
About Your Image
The Info palette displays measurement and
color information as you move a tool over an
image in the image window. In combination
with the Eyedropper tool, you can use it to
view the RGB (red/green/blue), Grayscale, and
HSB (hue/saturation/brightness) values of
your image. The Info palette is a handy tool if
you want to sample and then enter specific
color values in the Color Picker (covered in
detail in Chapter 3. When an area is selected,
this palette shows the position, angle of
rotation, and scale, allowing you to control
the precise placement and movement of
selections.
In addition, a status bar at the bottom of the
Info palette can be customized to display dif-
ferent file and image information.
Downsampling vs. Upsampling
In Photoshop Elements, changing the resolution and/or size of an image by adjusting the
number of its pixels is known as resampling.
Downsampling, which is the term for decreasing resolution by removing pixels from your
photo, is one of the easiest and most common ways to make your files smaller. If you take an
8 x 10 photograph of your grandmother and shrink it to a 4 x 5 image by reducing its pixel
count, you’ve just downsampled it. Photoshop Elements “throws away” unneeded pixels
intelligently, with little or no visible impact on the quality of your image.
But upsampling, which is the term for increasing resolution by adding new pixels to your
photo, should be avoided whenever possible. If you take a 4 x 5 photograph and try to enlarge
it to 8 x 10, Photoshop Elements has to add pixels to your photograph. Since it has to manu-
facture those pixels out of thin air, they tend to add a ghosted, fuzzy appearance to any hard
edge, the overall effect being that your image can look out of focus.
Because downsampling rarely detracts from the quality of your images, you should capture all
your original files at the highest resolution possible, whether you’re scanning an image or
snapping a digital photo.

Figure 2.34 Color mode displays can be changed at
any time from pop-up lists in the Info palette.
Figure 2.33 Any two sets of color information
(RGB, HSB, Web Color, or Grayscale) can be
viewed at one time.
Figure 2.32 To view the Info
palette, choose Window > Info.
To use the Info palette:
1.
From the Window menu, choose Info to
open the Info palette (Figure 2.32).
If you like, you can drag the Info palette
into the Palette Bin.
2.
Select the desired tool and then move the
pointer over the image. Depending on the
tool you are using, the following types of
information appear:
The numeric values for the color
beneath the pointer. You can view any
two sets of color modes at the same
time (Figure 2.33). Information for
different color modes can be displayed
at any time by clicking either of the
eyedropper cursor buttons in the Info
palette (Figure 2.34).

The x and y coordinates of the pointer,
and the starting x and y coordinates
of a selection or layer, along with the
change in distance as you move the
pointer over your image (Figure 2.35).
The width and height of a selection
or shape and the values relating to
transformations, such as the percent-
age of scale, angle of rotation, and
skew (which distorts a selection
along the horizontal or vertical axis)
(Figure 2.36).
Tip
It can be quicker to change units of meas-
ure using the Info palette rather than by
using the Preferences menu. Simply click
the XY cursor icon (it looks like a plus
sign) at the lower left of the palette to
pick from a list of measurement options.
Figure 2.36 Any change in the scale or transformation
of a selection or layer is visible in the Info palette.
Figure 2.35 The x and y coordinates of the
pointer are shown in the Info palette.
