Just shoot RAW and you can change it to whatever you want in PP.
Other than that set a custom white balance if shooting JPEG. But you are essentially baking in the white balance in a JPEG file.

===================

Yes, Todd = This is what I do.... RAW shooting Everything is the way to go. I do shoot in jpg ONLY with sporting events as I want the faster shutter speed from my Canon 5D Mark II. Everything else is RAW.

I was in Joshua Tree NP last month for shooting the super moon. While there, I tried wandering around one of the groves and shooting some of the trees in the brilliant full moonlight. It was after the moon was well up, and there was almost no color in the night sky, almost monochrome landscape, just a hint of a cream or washed-out yellow.

I didn't know what white balance setting to use. I tried several, ultimately leaving it on auto, thinking I would fix it in post-processing. I had read that moonlight had a color temperature around 4100-4200K, but any and all white balance adjustments look terrible. I tried applying several photo filter layers, and then almost completely desaturating the colors, that looks the closest to what I remember seeing. I prefer to spend minimal time post-processing, and more time wandering around and taking shots

My goal is to take photos that will capture how I felt when I was there. How do I expose for a moonlit scene, say in the desert with no humidity, that will capture the colors?

I was using a Sigma 20mm f2 art lens on a 5Dmark3 body, on a tripod.

thanks,
Wes

Wes, it depends on what type of effect you are shooting for. Like DavePine, billnikon, mborn, burkphoto, and others have stated, the color balance coming off the moon is just slightly different from the 5500K to 6500K of normal sunlight and really needs no correcting - unless you are trying to duplicate what the eye sees. mcveed and Architect1776 are correct that the eye becomes much more monochromatic but there is also a hue shift. In a dark room at night, the eye is nearly monochromatic. But with the bright moonlight (more like being in a movie theater), that romantic moonlit scene that one sees can only be reproduced by changing the hue. The eyes' night vision color shift is caused by a chemical commonly called vision purple. This chemical is always being produce by the eye and wraps around the eye's rods. As a photon hits the rod the vision purple releases its energy to multiply or increase the signal to the brain. But rods are basicly "color blind". Because the light levels are more like a movie theater, the cones also function but not at a normal capacity. The hue shift comes into play because the vision purple used by the rods has a pinkish or purplish hue to it that acts as a "filter" on the cones. It is not a Kelvin color change. If you want to produce that romantic color to the picture, there are special filters available at a hefty cost. Or you can get very close to the same effect by choosing the florescent color balance from your camera's color balance menu. Also, you may want to underexpose slightly and, if the camera allows it, desaturate the image slightly. Of course, the adding of the florescent hue and both the last two items can be done in post processing. Although I have done my romantic moonlit shots all in camera at the time of the shot, I'm sure you will be just as pleased with the results with post processing.
