Great Glamour Starts with Light but Finishes with Luminosity
One of the concepts I stress most with my students is that photography is all about the play of lights and darks; tonal value is more important than color! I find that, most of the time, the path to a great color image runs through a B&W conversion, at some point. It is much easier to make tone and contrast decisions when you are not being distracted by color. Once an ideal B&W is achieved, you can apply the B&W luminosity to the original color. The following example, from my last Glamour workshop, shows this process.
