Distorting Images
You can distort all or part of an image.
Original image and part of the image distorted.
To distort an image:
1 Select a layer or area of the canvas.
If you want to distort the entire
image, select nothing.
2 Choose Effects menu >
Orientation > Distort.
3 In the document window, drag any
of the selection handles to reshape
the selection.
4 If you want to see a more accurate,
but slower, rendering of your
changes, enable Better (Slower) in
the Distort Selection dialog box.
Enabling this option is particularly
useful in highly distorted images.
5 Click OK to apply the effect.
Free Transforming Images
The Free Transform, Set Transform,
and Commit Transform commands
work only with reference layers. Refer
to “Working with Reference Layers”
on page 246 for more on these
commands.
Correct Colors
Color correction lets you make
adjustments in the relative amounts of
the color components in an image.
Color correction is often used to
improve a color-casted or washed-out
scan. You can also use it to create
surreal color effects.
If a layer is selected, color correction is
applied only to the layer. If no layer is
selected, the entire image is color
corrected.
Color correction is based on adjusting
gamma response curves. You can
adjust the gamma curves for red,
green, blue, or all three color
components. The gray Master curve
controls all color components equally.
The curves describe how the input
color values are adjusted to create the
output (corrected) color values.
