LR Grayscale Conversion Primer

I am fascinated with Lightroom's Grayscale Mix palette - it is far more comprehensive than Photoshop's few controls for accomplishing this essential photographic effect.

The following images serve as a primer for graycale conversion in Lightroom. Colors and their temperature are key ingredients along with the color shifts you can introduce to 'create' a grayscale to your liking. Emphasis can be place wherever you feel it is needed to define sky, subjects, shadows and highlights at values you desire - it's rather amazing what Adobe has programmed into Lightroom for us, so start experimenting on a full scale image to learn what it can do for you.

Follow the sequence of images and the 'builds' I have created to accomplish the final image...

As you study the progression, you can see how different areas react to the 'color change' we invoke on a grayscaled RGB RAW image - from shadow area to midrange to sky, etc. Keep in mind that we have not left the RGB color space, so these images can be printed in color - especially if you do on to use Split Toning - or converted to an 8-bit, single channel grayscale.
