Lightroom - Black & White Conversion

To create a Black & White Conversion in Lightroom, you just open up the Basic Panel and select the pull-down menu labeled 'Profile'. If you are working on a RAW image you will see a whole bunch of options, just select the one labeled Adobe Monochrome. If you are working on a JPEG you will see just Color and Mono options.

Lightroom then converts your image automatically into a Black & White. It also adjusts the panel options in the rest of the Development Panel, so that only the effects applicable to monochrome are available.

Note: You may still need to target your tonal balance and contrast in the same way as you would for a color image.
