After a seemingly endless, although objectively not-so-very-long beta
testing, Lightroom 3 is finally out. Adobe released the public beta
in last October, attracting 600,000 users to try it and to share their
thoughts in order to help improving the popular RAW converter. The
result has been released early last week. Now we'll take a look at
the most (and less) important new features based on available press
information.

Improved
noise filtering
The separate filtering of various noise components such as luminance
and color noise was already available in earlier versions of Lightroom,
but results were not always satisfactory. When trying to remove stronger
luminance noise, too many details were ruined. The new version boasts
a redesigned filter, offering much better results, preserving more
details even after stronger filtering.

Film grain emulation
If, instead of smoothness, you are aiming for a grainy effect similar
to that of analog pictures, try Lightroom's new film grain emulation.
There are three sliders to set the grains' Amount, Size, and Roughness.

Lens correction
Automatic lens correction also gained an important role in Photoshop
CS5, released recently. This feature facilitates the automatic removal
of major optical defects, such as chromatic aberration, geometric
distortion (e.g. fish-eye and pillow effect), or the darkening of
picture corners (vignetting). The developer's new software, Adobe
Lens Profile Creator, lets you create your own correction profiles
for your cameras and lenses. All you need to do this is to take a
picture of a test graphic, and spend some time tinkering. The correction
file can then be used in Photoshop CS5 and Lightroom 3 as well. Based
on EXIF data, the software picks the camera/lens combination and attempts
to remove all optical defects. You don't even have to take a test
picture in all cases. A bunch of correction profiles will be available
with the software, and most probably, over time, several updates will
be downloadable.

Perspective correction
The new perspective correction feature satisfies a long-time demand.
n earlier versions, you could crop and rotate the image, but did not
have the possibility to adjust the non-parallel edges typically found
in wide-angle pictures. Finally, you don't need additional software
for such correction.

Improved performance
An obvious advantage of the new version is improved speed. The increase
in version 3 was much needed due to the ever-growing resolution and
file size of RAW images.
Support
for video files
In the last few years, more and more DSLR cameras support video capture.
Their users can now process their movies along with RAW stills. The
software supports playing such movies in the Library section.

Sharing slideshow videos
Until now, slideshow presentation of your pictures was only available
inside Lightroom. The new version lets you save such slideshows as
a video. It also offers several options to create spectacular presentations.
You can specify a background, add animated captions and music to your
pictures, save the whole bundle in MP4 format and use an external
player to view it anywhere.

Watermark settings
The new watermark options allow the easy fitting of almost any caption
of graphic to your pictures to protect them for web usage. The transparency
and effects of watermarks can be freely adjusted, and the objects
rotated and resized.

Other new features
Finally, a glance at the things we found less important. Others might
find the totally revamped Import interface of critical importance,
and it is indeed much better than the former, rather awkward one.
There's a remote camera control feature, if you are adamant about
having Lightroom control your shots. If you take studio photos in
RAW format, this can be handy. There's Flickr support, so that you
can instantly upload your finalized photos to the popular photo portal.
And finally, there's also a bunch of new printing templates.
