"I'll put something together over the next few days." 

Looking forward to it. Personally, I would like something in between Maxwell's equations and 'just use it.' I've started reading Birn's Digital Lighting and Rendering, and I like his practical approach, though strangely, he doesn't seem to say a lot about gamma correction per se other than using the histogram for adjustments. Maybe he didn't get the memo.
