White balance and lighting

[Kent Beeson]

“You may not want to gel them to match exactly, though. They should give off at least some of their natural color temp; even our eyes see differences in degrees kalvin. ”

You’re right, I needn’t be too zealous…

Thanks

If you can get the lights gelled to give you about 5000K you should be fine. The lights may be on the warm side compared to the windows (especially if it’s a cloudy day) but that usually looks better than anything showing up cool (blue) coming in from the windows. Try some different gels and see what looks best, and as David mentioned unless you get lucky and have an overcast day, your light will change throughout the day anyway. Direct sunlight will range in the 5600K+/- range in the middle of the day, warmer (lower numbers if it’s clear out) in the early morning and late afternoon while the sun’s still visible. Cloudy or overcast days will range in the 6500K-7500K range. Keep in mind many cameras give inconsistent kelvin numbers for the same balance, so don’t worry if you don’t get ‘exact’ daylight kelvin numbers like 5600K. Just look at the image on a monitor you trust, and if you’re close no worries. (you can do a lot in post to correct color and balance anyway, but why make extra work if you can avoid it? Just know that if you’re off a little bit, not a big deal to fix)
I always play it safe and balance for the coolest light (highest kelvin temp) and let other light sources ‘warm’ things up. This usually works okay, except when the discrepancy between kelvin temps is more than about 2000K-3000K. If you can hit something around 5000K-6000K with the lights looking normal to slightly warm, you should be okay with whatever happens outside.
Good luck! You might also check and see exactly what kind of bulbs the light fixtures use. If you’re really lucky, you might be able to find daylight balanced bulbs and just replace them! Remember to check what the balance is already coming from those lights… you may already be golden if they’re in the 4500K+ range.

Hi.
Where can I find preset XDCAM already created for PP of xdca EX3.
Thanks
