I previously demonstrated the use of luminosity masks on this image to bring out color in a washed out sunset.  I decided to redo the video using Lumenzia (my new interactive luminosity masking panel) to provide a direct comparison of the two approaches on a simple image.  It doesn’t get into any of the advanced features (the zone picker, refining masks by color, etc), but I think provides a sense of how the Lumenzia workflow can speed up and simplify even simple retouching jobs.
