In this latest InstaMask tutorial, I show you two ways of using luminosity masks – one simple method for exposure blending, and another, more complex method for targeting a very narrow range of tones.

As you’ll see, luminosity mask functions are extremely simple in InstaMask. We just create a mask, then press Select. That mask now becomes a selection that we can paint.

For more complex masks, we can use something called Intersecting. This is where we can add or subtract masks to make extremely fine selections. As you can see in the video, it was it wasn’t possible to create the mask I wanted with any standard luminosity mask, but using a colour mask, and subtracting a bright mask, we got the selection we needed. And it just took a few clicks.
