Adobe lightroom comes with added lighting effects for editing a picture.
A lots of presets and lighting options are available here.
As I felt this software is a combination of adobe bridge and camera raw plugin .
Most of the options comes with camera raw can be accomplished using the software.
For editing a picture we need to export it .
The negative side is that when added lots of pics to lightroom then the task of finding a particular picture from it becomes hard.
Also in an i3 processor its performance is not satisfactory.
Sometimes there may be lagging.
The toogling from lightroom to other editing software like photoshop is also an added advantage.
