I got my Phantom after our last snow was pretty much gone and I was upset because I REALLY wanted some cool snow shots. Well, we just got an inch or so so I'm planning to take advantage of it tomorrow am. However, I know jack squat about what filter to use in what lighting. I have: UV, Polarizer, ND 4 and ND 8. I have noticed that the UV filter really makes things pop. I know that that is a very commonly used filter. But what about if its cloudy? Or super bright? I was fond of the effect of the Polarizer as well. Can the filters be used in conjunction with each other,,,ie UV with Polarizer on top? Or are they stand alone only? I am perfectly willing to learn by experimentation in every other circumstance, but this is probably my only chance to get shots like this for 8+ months so I'd like to get as perfect as possible, so advice is greatly appreciated, as always.
