Hue, Saturation, Color, and Luminosity

In this movie, I'll demonstrate how to work with a final…group of blend modes, which are hue, saturation, color and luminosity.…Together, they make up the component modes.…So called, because these blend modes divide an image into its color components.…And, I'll be discussing these blend modes in opposite…order, because that's the easiest way to understand them.…I'll switch over to this image of the model against the sky.…You can see that she has a layer mask, which will become…important in just a moment.…Now let's say, I want to keep all the detail information that's associated with…the model, but I want to let the blues from the background show through.…

Then anytime you want to keep the luminence levels…for the active layer, then you change the blend mode…in the upper left corner of the layers panel,…from whatever it is, normal in my case, to luminosity.…And notice now we can see all the detail of the model,…but we're seeing the color of the clouds show through in the background.…Now you may ask, well why are we seeing the luminous levels of…
