[QUOTE="BackdoorArts, post: 291099, member: 9240"] [b]Re: Better B&W Conversion Using Multiple Hue/Saturation Layers in Photoshop & Element[/b] If you're into the science of color, or want to try and understand it a bit better, here's a pretty good explanation of how Hue, Saturation and Value (their term for what LR calls "Luminance") work together, borrowed from deep within NC State's website (likely from a class syllabus). [URL="http://www.ncsu.edu/scivis/lessons/colormodels/color_models2.html"]Color Principles - Hue, Saturation, and Value[/URL] It's way more technical than you would ever need, and unless you're a math geek like me you can skip about the first 1/2 until it gets to "[B]The Hue, Saturation and Value (HSV) Color Model[/B]", though some of the stuff before that helps explain it. I believe this is taken froma class dealing with reading MRI's, but some of the color tools will be very familiar to PS users. For the non-geeks among us, the short definition - Hue is [I]Color[/I]. When you you change Hue you are shifting the 0 point of your color spectrum around a 360 degree wheel that starts and ends with Red. When you drill down to a specific color and change its Hue value, you are only shifting the spectrum of its light, while leaving the others alone. [/QUOTE]
