As I'm encountering LED stage lighting more and more, and as my trusty
K100D Super doesn't include a WB setting for them, a question for the
physicists and lighting gurus on the list: what is considered to be the
colour temperature of typically available LEDs? Is there a recommended
near-enough equivalent setting among the WB choices?
When I run pix through ACR after the shoot, I find that I'm getting
more-or-less reasonable results with ACR's temp/tint sliders near their
extremes; eg 2000/-128 or else something like 11,500/-64.
(I'd love to sneek up onstage before the show and attach a grey card to
something so I could keep calibrating during the performance.
Sometimes I'm lucky and there's a greyish keyboard onstage I can refer to.)
I suppose that LEDs present an near-impossible task since they are made
up of clusters of green, red and blue LEDs whose brightness is varied to
get the desired colour. I expect that the colour-temp of each
colour-type of LED is different.
Anyway, anyone have a suggestion?
