When I manipulate my digital photos what exactly am I doing?

I am using adobe lightroom to "develop" my digital photographs. While I have a good intuitive grasp of how to change photographs the way I want to but I would like a bit of a theoretical foundation. Specifically, I want to know what is happening numerically when I use the "exposure" or "fill light" sliders and also what happens when I use the color-specific hue, saturation and luminance buttons. As detailed as possible please. A standard computer science reference would be a fine answer.
