kinds of lights and even gel set windows to make outdoors match tungsten. (The funny part
is Hollywood is still based on gelling everything to tungsten, since that's the film we shoot,
but almost no lighting is tungsten anymore.)
The best place to buy gel filters, which are just colored sheets of plastic, is your local
theatrical stage and lighting supply store. They are a couple of feet on a side and cost a
few bucks each. You cut them with scissors and tape them where you need them. Popular
brands are Roscoe and Lee. You can get a free sampler from these stores to try out which
color works best before you blow a whole few bucks on a full size filter. In the stage world
we worry about selecting from among the hundreds of colors they offer. Get the book for

How to Change the White Balance of an Existing Image
SUMMARY
That's it. I have no idea why people make this so complicated. Just use what looks good.
A1/2 White Balance Examples
see also White Balance (page 44), How to Change the White Balance of an Existing Image
and The Expodisc.
Note: The last row of each shows the WB setting in degrees Kelvin, or K. Tungsten is the
same as 3,200 K, Daylight is the same as 5,400 K, Cloudy is about 6,000 K and Shade is
about 7,500K.
Explaining where and why we calculate Degrees Kelvin is complex so I'll skip it, but what it
does is easy to remember: the more degrees set in WB, the warmer the image looks.
