I think I have white balance issues, but I'm too new to know. I have it set in cloud mode on a Nikon D3200.
Yep he's blue and it's a white balance issue.
Here's how blue he is:
I adjusted the white balance until his skin color on his left cheek was the average for a Caucasian adult. I don't know if this guy is average but it's a fair bet he's pretty close. Human beings are basically orange leaning red or if you prefer we're red leaning yellow. On a color wheel from red you can move clockwise toward yellow or counterclockwise toward blue. Think of a classic round analog clock so that red is 12:00. Human beings are roughly 1:00 -- your guy here is 11:00.
You set the camera to a white balance preset: cloudy.
But your condition is shade. Shade is much bluer than cloudy. Look at the bright spot on his upper right forehead. That spot is catching a reflection of the sky and it's blue -- it's so blue that it's still blue after my adjustment. There was a blue sky up there and your subject is in open shade.
Most people aren't sufficiently color sensitive to catch this degree of discrepancy and will be happy with the photo as you took it.
You're seeing it which is good so now since you see it you need to fix it.
Your camera provides theses options:
1. Auto white balance.
2. White balance preset including degrees K.
3. Custom white balance.
4. (Raw file with reference target).
Options 3 and 4 work. Learn to set a custom white balance and start getting in the habit. It's easy and very effective. All you need is a piece of white Styrofoam. Here's a photo of me using the same a couple weeks ago.
That piece of Styrofoam I cut from the bottom of a food tray after I ate the Bok choy that was packed on the tray. You can't buy anything that works better. I carry that with my camera and what you see me doing there is option 4. The Styrofoam card will work for either option 3 or 4.
Option 2 is imprecise -- you just discovered that. If you had used the shade preset you might be happier but odds are the photo may have been over-corrected and too yellow. The presets have the advantage of being consistent but they're rarely accurate. Accurate isn't necessarily that important but it's a nice place to start from.
Option 1 is auto white balance. The only way your camera can measure the light color is with a reference target like the Styrofoam card. In auto white balance it uses computer algorithms to make an "educated guess" at measuring the light color. It'll guess wrong more often than it'll guess right. Auto white balance will frequently be as far off or worse than what you got from the mismatched preset above.
Learn to use your camera's custom white balance function, get in the habit of doing that and this problem is over.
