In-Depth Information
A little noise here and there will not
always present a problem; the main
issue is whether or not the noise will
be visible when the image is printed.
Zoom into the image to check for noise.

Because other adjustments can af ect
the appearance of noise, you should
check for it at several points during
processing. To reduce or remove noise
from photos in Lightroom, use the
Noise Reduction controls on the Detail
panel; see Figure 4-59.
In most cases, noise reduction is best
done before sharpening, as any noise
present in the image will be increased
when sharpening is applied.

Luminance: reduces the appearance of gray/black speckles in the image. Be
conservative applying Luminance noise reduction; i ne detail can suf er. Applying a
value other than 0 enables the Detail and Contrast sliders. Detail helps preserve areas
of i ne detail in the image, while Contrast increases edge dei nition in those areas.
Color: reduces the appearance of color noise, which shows itself as multicolored,
sot blobs in the image, especially in shadows and solid-color midtones. Color
noise reduction also provides a Detail slider.
h ere are no magic formulas for noise reduction here; work with the sliders at
various zoom levels to get the look you want.
SHARPENING
Is the image in focus? If not, you might well choose to work with another capture.
With very few exceptions, a photo captured out of focus can't be i xed with
sharpening in post-processing. Conversely, the appearance of sharpness in a
capture that was made in perfect focus can be enhanced dramatically.
