Lightroom
combines photos into “collections” – virtual gatherings of files that
can quickly search. It stores information about keywords, previews and
metadata not in each graphic file, but in a centralized database (the
SQLite engine). Therefore, the database can be accessed and about the
photos, which are now in the archive on DVD. The size of the program is
significantly smaller than Bridge, it runs faster and takes less RAM. In
general, Lightroom is aimed exclusively at photographers who are
interested in processing and cataloging photos, rather than integrating
everything and everything. Another feature of the Photoshop Lightroom
package is the separation of the process of working with pictures into
separate stages. Each of them has its own functional module with a
corresponding set of tools and palettes of settings.Lightroom’s
functionality includes not only a RAW converter and image processing
tools, but also a powerful photo cataloging system, as well as tools for
creating slide shows and web pages. As in many modern RAW-converters,
Lightroom uses the principle of nondestructive editing. This means that
information about all the operations performed by the user and settings
is recorded in the service file, while the original image is kept
unchanged. Such an approach allows not only to minimize the probability
of irretrievable loss of originals of processed images, but also makes
it possible to create and print many different variants of the same
image without having to save an appropriate number of full-fledged
graphic files that quickly eat up free space on the hard disk. At the
end of the work on the image,the user can save his processed version as a
separate graphic file.
