Polarizer Questions/ Advice Wanted

I have a t3i and I will be filming with just the kit lens this winter. I was wondering if a circular polarizer would be worth buying to bring out the blue in the sky and keep the snow to a not overpowering exposure. Are there any custom exposure settings on my t3i that works well for filming on the hill? Would filming in a flat picture setting be my best option then just colour correcting in fce?

Thanks for you help and bare with me while im just learning.
 
polarizers are always a nice thing to have. I'd get one. Shooting in manual would be your best bet, cameras autos always screw up snow shots. unless the snow mode is good i guess.
 
dont cheap out! remember any glass in front of the lens will affect image quality as much as any element of the lens. I'd say B+W for an L lens, but maybe a hoya multi coated one for yours? hoya makes good stuff. Also, get circular, and dont make the mistake of leaving it on your camera when you dont need it. and be sure to adjust it to kill the right glare, it can increase the bad glare just as much as it can reduce it when used improperly
 
I don't know if you're being sarcastic, but here goes.

Polarizer = filter to filter out reflections, often abbreviated as CPL (Cirecular polarizer)

ND = Neutral density filter, it just darkens the whole image in a neural way, allowing you to shoot with slower shutter speeds.

As for the OP:

A good, budget option is buying a 72mm (or 77mm if you plan on buying ridiculously expensive lenses in the future) filter thread with a 58mm -> 72mm adapter ring. That way you can use on filter for all your cameras. You're going to have to swap the CPL all the time, but it saves you a lot of money. And the money you save, you can use to buy a better filter.

Get this one if you don't wanna use stepup rings:

Or this one if you do:

No, because more likely than not he wants more than a 2 inch depth of field. He'll be fine with a faster shutter speed and smaller aperture.
 
Both of you guys are right, but I'm guessing he wants the polarizer not to have shallow DOF but to make the sky look bluer. A nd is a good thing to have though, you don't always want to control your exposure with shutter or aperture
 
i wont be using a shallow depth of field cause I am going to purchase a glidecam where I need everything in focus so i'll be cranking the aperture to like 10 or 11 most likely.
