A noisy image
of the enhanced features in Lightroom 3
is noise filtering, which has been pretty nicely reworked.
We'll compare the filter in version 3.0 to the same feature
need a noisy photo for this purpose. The above image is
part of a photo taken with ISO1250 sensitivity in half-shadow.
A base for comparison
we begin, let's take a small detour and see how Photoshop,
king of image editors, deals with the same noise.
We used the built-in noise filter on 70%,
and since it blurred the photo quite much, we also applied
some detail enhancing. You shouldn't overuse the latter
with high values as it tends to bring noise back.
let's see those Lightroom versions. Earlier versions up
to 2.7 contain noise filtering under Detail,
along with sharpening and color defect removal. There are
two sliders, reducing Luminance and Color

eliminated, more details kept, but still it could be better.
can find the filtering feature in the new Lightroom version
at the same location (under Detail), but
now it offers 5 settings instead of 2. The Luminance
and Color sliders still control basic noise
filtering intensity. However, both have a Detail
slider now, which allow reclaiming some of the details blurred
by filtering. The Luminance section also sports a Contrast
setting for enhancing detail contrast in darker areas.
Of course, be cautious when increasing Detail and Contrast
as well since they can reintroduce noise or unnatural fragmenting
to the picture.
Filtered (Lr 3.0)
we set Luminance to 70%
and left Color at the factory default of
25%. Both Detail slider
were set to 50% by default. We increased Luminance Detail
to 80% and Color Detail to 70%
to reclaim more of the details. We can increase them more
freely than in Photoshop as such high values still don't
bring back much of the noise.
Finally, we set Contrast to 70%.
This is pretty much optional as it doesn't always have a
visible effect on the picture.
The result is still not perfect, but that isn't something
we would expect anyway. However, the picture contains less
noise than the above ones, and even finer details can be
