shooting in snow, settings?

I'm shooting ski action but the snow appears a little greenish. Will using a polarizer reduce this or do I need to adjust the settings. I've messed around with the internal ND filters and the iris a little but then it's a little too blue or dark. Also, I don't fully understand white balance. Any insight would be greatly appreciated. Thanks, Gavin

Sounds like a white balance problem. Instead of using the presets, manually set the white balance. Set the white balance to manual A or B, aim at a clean white patch of snow, zoom in so it fills the screen, then press and hold the white balance button (awb) on the front left bottom of the camera.

Oh, I don't think a polarizer won't help with the color problem you describe.

Agreed, polarizer will not help color problems (it could actually add more problems if not used properly). I shoot in the snow a ton, as Hans said, white balance on the snow. ND will be need to be on regardless, I even add another ND filter on my lens sometimes. I keep my zebra's at 80% and 100%, just make sure your not overexposing and have a blast.
 
Re: shooting in snow, settings?

Cjgrosso, when you say you have your zebras at 80% and 100% how do you use them? When I shoot in snow i have a rain cover on and can't take the time to open the lcd screen to access the zebra button. 90% of my shots are run n' gun. So I just leave it on 80% and only allow a little hotspots. I would love to be able to program the zebras to a user button though...
How do you shoot? Is there a better way to use zebras?
 
Re: shooting in snow, settings?

heres something I can answer..i read this forum all the time, but dont write ****

I work exclusively in worldwide ski films, X games style stuff, so my entire life revolves around snow filming.

Like someone else said, auto white balance to the snow. In some instances, this will unfortunately give the scene a rather bluish "cold" tint. What I like to do, and what is usually effective, is to find a neutral color like a tan or brown (jackets do well, or color cards) this will give the snow a natural yet non-washed out color while maintaining a good color rendition over the entire scene.

Another way is to go into the color settings in the menu, and push the reds a few stops + beyond its current setting. Will give some more life to the sky and landscapes and gives the snow a less brown and more of a natural off white (or crappy grey) depending on your location of shooting.

My best tip is to put zebra indicator on, and make sure that the snow has a slight hint of overexposure in some areas. If the snow is exposed perfectly on a sunny day, then the rest of the scene becomes underexposed due to the intensity of the bright snow.

Go out in your yard and experiment with the cam before you try to tweak the settings on the hill. Athletes dont like waiting for your camera to be ready.
 
Re: shooting in snow, settings?

i set zebra to 100% and see that the brightest spot of the shot is showing the zebra (in sunlight). will give you a white snow. the auto-iris ends up greyish.

definitely manually whitebalance. the preset is tinted IMO on snow.
