Custom Luminosity Masks with Color Range in Photoshop

Luminosity Masks are all the rage these days it seems and rightfully so, they are extremely powerful.  A Luminosity Mask is nothing more than a selection of  the luminance range in your image.  Think of it like separating lights, darks, and colors, kinda like doing the laundry.   Sure you could wash all the clothes together, but you could run into color bleeding onto lights and then your wife will beat you into submission (maybe that is just my wife).

Luminosity masks are similar to doing the laundry in that you can separate lights, darks, and colors and “wash” them separately in different cycles.  In photo post processing this becomes important when you want to modify one color or tone and not affect the image as a whole.  There are many ways to get really good Luminosity Masks these days, the Zone System Express is one of those ways.  However, one very powerful but often overlooked tool is sitting right on your workbench right now.


In the Select Menu Item in Photoshop rests a tool called Color Range.  By using Color Range you can make varying selections in your image from points that you select on your photo.  Photoshop analyzes all the other tones and colors that are similar to your point and makes a custom selection.  You can then turn this selection into a mask and use it on any Adjustment Layer or item in your layers palette.

In today’s free tutorial, I will show you how to use the Color Range tool in Photoshop.  I will break it down into all of it’s various parts and outline all you need to know to start making your very own Luminosity Masks in Photoshop.


Custom Selections in the ZSE

The Zone System Express has a Custom Color Selection built into the Extension, however, it adds the signature Zone System protection measures to the mask to ensure they blend well with the rest of the Zone Selections.
