3) You can now use the
Paint Bucket Tool
to change the border to the same red color
as the costume. The change is shown in the image at the far right bottom of

Dodge
and
Burn
are two photographic terms that originated with developing film in a dark-
room. Dodging is a technique that brightens up an area while Burning darkens an area. It
can be applied with great precision by masters of the darkroom. Photographers sometimes
spent days Dodging and Burning an image to get the exact exposure that they wanted. An-
sel Adams referred to dodging and burning as man's ability to correct God's tonal errors.
In the days of film photography, these techniques often turned a mediocre image into a
masterpiece.
Referring to
Figure 38
, note the two drop-down menu selections in the
Options Bar
. The
one on the left allows us to choose how we wish to apply the adjustment — shadows,
midtones, or highlights — and the one on the right allows us to specify the degree of change
that we wish to apply with each brush stroke. A setting of 15% to 20% is common practice
when using these tools. The effects are cumulative. In the upper left of
Figure 38
, I have
made 2, 4, 6, and 8 passes over the gray background with an 18% exposure setting. The
image shows the cumulative effects of Dodging and Burning.
In the image on the upper right in
Figure 38
, I dodged along the branches of the plant to
emphasize the spiral growth. I also burned the perimeter of the image to create a vignette
effect thus forcing the eye to the center of the image.
Along the bottom of
Figure 38
, I have presented before and after versions of a photo taken
in the Palace Saloon in Prescott, Arizona with only ambient lighting. Although there are
a few incandescent lights in the saloon, the major source of lighting is the windows and a
large skylight.
In the before shot on the left, the only detail that is clearly visible is where the light through
the windows strikes an object directly. The after image on the right has been burned in the
highlights and dodged in the shadows. As a result we can now see details of the chairs and
cabinets.
