Press and hold the Shift key, and then click and hold the bottom-right corner of the transform box. Drag
toward the center of the box to make the box smaller. Pressing and holding the Shift key ensures that
the width and height are constrained proportionally. In the Options bar at the top of the screen, note that
as you scale down, the percentage values begin to decrease. Scale the butterfly until the horizontal val-
ues are approximately 25 percent. Press Enter (Windows) or Return (Mac OS) to commit the transform-
ation (you can also press the Commit check mark ( ) on the right side of the Options bar).
You can view the scale percentage in the Options bar.
You have reduced the width and height of this layer by 75 percent. This also means that the original
pixel data has been lost through the scaling process (also called downsampling). This creates problems
if you decide at some point to make the image on this layer larger.
You can type 25 into the Width text field in the Options bar and click the Maintain aspect ratio icon
(
) to reflect the exact percentage in the Height text field.

Choose Edit > Free Transform, or use the keyboard shortcut Ctrl+T (Windows) or Command+T (Mac
OS), to turn the transform bounding box on again. Press the Shift key, and then click and drag the
bottom-right corner of the transform box diagonally downward and to the right to scale the image to ap-
proximately 400 percent. Remember to watch the percentage as it changes in the options W (Width)
and H (Height) text fields. Press Enter (Windows) or Return (Mac OS) to commit the scale transform.
The butterfly layer after rescaling.
The image is fuzzy and pixelated because you forced Photoshop to fill in pixel information. This is
called destructive editing because the original layer lost its detail through the resampling process.
