Helen,

Thanks for taking the time to read, and for your comments. You raise some very good points, and I'll address those in some additional editing!

My specific mention of CC units was in relation to the Color-Pro 3F, it's one of the 3 ways that meter displays filter values. It does bring up the point though that I should at least draw attention to the other filters besides the decamired series.

In the next revision, I'll add some more examples and include a few GS lamps.

Thanks again!
