That does seem to be a straightforward approach, easy to visualize and

Is the terminology decaying predictably, linearly, or as a function  

candidates for overuse:

1) workflow.  3+ appearances per paragraph in facility PR.
2) LUT.  Seems to apply to everything.
3) linear.  In grading, has come to mean "video look."
4) high dynamic range (HDR)  How is that defined?

I like to differentiate "flip," a vertical inversion, from "flop," a  
horizontal one, but few clients know of this subtlety.

A director once arrived late to my session where already were sitting  
a famous DP and clients.  He asked, flamboyantly, "Where are your  
upper mids."

Aside from the terminological aspect, which was better addressed years  
later here, my approach was to give him a number, which came out as  
"67."   "Try 64" was his response.  Everyone sighed happily.
