Load
the photo
This
image is rather dark, at least in the lower and right regions.
On the other hand, the background on the left is too light
to not be ruined by some additional lightening.
Photoshop
CS5's new pseudo HDR feature offers a solution. Our goal
is to lighten the shadowed areas while leaving the already
light parts untouched.

Pseudo HDR
You'll
find the new tool under Image/Adjustments/HDR Toning.
The dialog contains a large number of sliders.
Under
Method, select Local Adaptation, which does
a good job by default. All you need to do is refine the
results. We used the above settings.
Radius
controls how far the lightening goes from the edges. Low
values produce a thin, detail-emphasizing effect, while
higher ones lead to spotlike lightening.
Strength
controls intensity.
Gamma
specifies the ratio of light and dark areas: high values
bleach the image to grey and ruin contrast.
Exposure
controls overall lightness.
Detail
lets you increase or decrease detail contrast to produce
blurred or painfully detailed pictures.
Shadow
darkens or lightens the darkest areas, while Highlight
does the same to the lightest ones.
Finally,
Vibrance controls the saturation of the most intense
colors, and Saturation the intensity of all colors.

The curve
Open
the Toning Curve and Histogram area at the bottom
to check the tone distribution on a lightness histogram
and learn how much dark colors dropped black or light areas
burnt out.
The
curve on the histogram offers additional control over image
lightness. In this example, we won't be using this feature.

4.
More friendly
Dark
areas in the finished picture are much lighter and more
balanced, while the light parts did not burn out any more.
Next
time we'll be continuing from here with a very simple adjustment
which will offer a glimpse into another new feature in CS5.

Plastic
Significantly
increasing Gamma and Radius while also slightly
adding to Exposure will produce an overcorrection
in tone, which is rather popular on the web. Use the HDR
Toning feature a second time as well to reach a truly
dramatic effect. |
