Holy cow Greg - never got past the first 30 seconds of that.
I thought it was pretty cool, but -extremely- early in the dev cycle.
Go to Home
Depot and look at their charts. *Soft White and Daylight are opposite ends
of the spectrum. *Beauty is in the eye of the beholder and all of that
stuff, but I find the daylight bulbs to be a very true color rendition.
There are people here who will delve into the heat ranges and what all of
that means. *I'm not one of those. *Sorry - can't offer a specific
recommendation beyond what I just stated.
Soft white = yellow as hell, like my damned _teeth_! *Screw incan!

Here I am falling into the trap of the Wandering Thread, but...
It piqued my interest to see CFLs used in photo lighting. I hadn't
seen that before. While I am aware that CFLs are available in
"Daylight" and "Soft White", among other shades, I believe I have
noticed a difference between the light from those bulbs and their
Incandescent counterparts. So my first thought was, I wonder if there
are white balance presets for the CFL versions of those "colors" on
the latest cameras. And then I wondered if the various manufacturers'
offerings are at all standardized in this regard.
But the overachiever could set a custom white balance, no? That's my
main question, and I'm not so sure the answer is yes. It is my
impression that the white balance sets individual gammas for the three
colors. But it does so assuming a reasonably smooth spectrum. CFLs, as
I barely remembered, have "spikes" in their spectra. They are not just
a different "color temperature", ( a shifted smooth curve) they have
well, this

And I wonder if setting a custom white balance can compensate, given
that the "bands" the white balance adjusts are much wider than the
anomalies in the spectrum.
