Easily Work With Luminosity Masks

Posted in , ,

Tagged with

A luminosity mask is a powerful way to adjust very specific tonal regions in your photos. However, they can seem daunting to work with. In this Short Clip, see how ON1 Guru Scott Davenport works visually with luminosity masks to quickly and easily create masks for specific elements in his photo. With the classic masking mantra “black conceals, white reveals” in mind, working visually with the mask view makes luminosity masking much more approachable.

    A great approach to masking. ‘Play the sliders to understand what they when mask?’ Though I have heard it before, this really helps bring my understanding home. Thanks

    Is there a way to use this technique to do a cut out like a sky replacement? I need to replace a sky in one of my photos, and there are a lot of fine but dense tree branches (willow trees). I’ve tried the typical masking, perfect mask, etc., but the cut out looks unnatural.

      Hi Yuti… you could try a luminosity mask if the trees are dark and the sky is reasonably bright. A color range mask might better suit this situation. A color range mask works similarly… use the eyedropper to select a color in the sky, then adjust the range slider to fine tune it.

    Fantastic. Thanks much Scott. I know, eventually, luminosity masks will just “make sense”. But until then – great tip to just view the mask and play with the sliders.

      Sure thing, Chris. Luminosity masks do take some time to get comfortable with. It gets easier with practice :-)
