It’s back to school basics. What makes colour?
Hue, saturation and luminosity (HSL) all contribute to what we define as colour. The course notes goes some way to explain HSL but I needed to see the practical effects of the three elements. Below you will see the results of one image that I have dissected in Lightroom where HSL can be clearly separated. Each image shows the histogram and slider position. Please read the entries under each set.
