GE Reveal light bulbs - which film?

Mer's and other ambient light mavens,

 

<p>

 

Does anyone have any experience shooting indoors in ambient light when the house is lit with the new GE Reveal bulbs? The light is much more like outdoors than tungsten. Outdoor film? Filters?

Shoot , Fuji films handles the multible colour temps better then

kodak or agfa , and a good printer can pull a good skin tone out

of a tugstin shot with fuji press .

Tried to find the colour temp GE Reveal bulb but couldn't find

I've picked up a pack of the Reveal bulbs but haven't run a test yet.

I suspect they're much closer to a 3400K tungsten photoflood than to

daylight. (Standard incandescent bulbs are much yellow/orange than

tungsten photofloods.)

Short answer, no. you might try GE web site (as hope???)

I find it rather difficult, even in manufacturer's brochures or web

sites, to find color temperatures -- daylight fluorescents that are

not quite daylight, others "blue light" a little beyond, very little

actual color temps. Some, like ge/sylvania, express it only for

certain bulbs, maybe like "pro" films versus consumer films. Anyone

know a brand/bulb color temp chart? Some of the web sites have color

temps, but, again, seemingly only some bulbs.

Does taking daylight slide film and then holding color compensating

filters up provide a way of checking?

Finally, I/you may have to re-calibrate, but I found an incident meter

(an old Gossen LunaPro), with readings through red, then blue filters,

subtracting the difference, gave a crude, but workable color temp

meter. If you consider the stop difference (which is logrythmic

subtraction = division or ratios) is a ratio of the red/blue

intensity, it makes some sense (a real color meter has (typically)

three wavelengths, I think green the third). I wrote all the stuff

down for "when I was caught without", but never have any of it with me

when I am caught without. If anyone wants to try some curve - fitting,

not a bad exercise. I've not tried same with the leica meter, but it

was roughly linear in the typical visual range -- low end a standard

2800 tungsten, a 3200(3400?), and a daylight gel over tungsten - 5500.

That's how I know some "daylight" bulbs are 4500 or so.

I spoke to someone at the GE Helpline, and he said the Reveal bulbs are 2870K. I was going to look into the new HID headlights, which are sold at 5500K and 6000K. Has anyone looked into these?
