Do I need a Polarizer

I just received my GS250 last night and it was really great though I'm not too happy with the digital stills (I'm not really planning on using it though). It's smaller than I thought, maybe I didn't hold it long enough at the store.

Now I'm off to buy the accessories. I'm stuck with this one. I bought a set of 3 filters for a very good price but it doesn't include a polarizer. I bought UV, ND .6 and flourescent set but without the polarizer. Do I need to buy a polarizer?

Thank you very much in advance.
Elfi

If you'll be shooting on water or snow where there is a lot of reflected glare a polarizer will help cut the glare. Otherwise, it will acts similar to an ND filter by reducing the amount of light reaching the cam.

Good luck.

Does that means that if I get the circular polariser...it can act as a neutral density filter as well as reduces reflection from non-metal surfaces?

so if let's say for a budget case..can I jus buy the polariser for the time being?

I can see myself shooting from inside the car/tour bus...through the glass...does circular polariser helps to cuts the reflection there too?

Thanks^^

Yes, it will cut the light that gets to the CCD. It just isn't as calibrated as NDs are but that might not matter. If you want to find out what it is you can experiment if your cam has manual iris on it. Set up a shot without the filter and see what aperture the cam needs. Then add the filter and see what the new (wider) aperture is. The difference, maybe 1 stop or 2, will be the amount of light reduction your polarizer ND creates.

Well, you can get by without *any* filters if you shoot carefully and don't care what depth of field you get. But a polarizer is a good first step, I guess.

Not too much. It's more for glare.

Good luck.
