Lightroom is often used by photographers and is great for mass edits (event photography), organization, metadata and copyright/watermarks. It does not give you the same abilities to edit as PS, but allows you to go faster in your large scale global changes.

SPLIT TONING aka COLOR GRADING
"Color grading — also known as split toning — is a great way to give your photographs a unique and stylized look, adding a hint of color that can create a certain mood or draw on photography’s rich history to bring out a vintage feel.
The term split toning comes from the idea that you would add one color to the shadows, and another color to the highlights, effectively “splitting” the tones of the photograph."
