Default photography - polarizer filter

circular polarizer filters . . . talk to me.

got a few questions.
i know they add more contrast to your photo's,
but whats the difference between a linear and a circular one ?


im after a 52mm screw filter for the nikon D40, can anyone recommend any brands or anything ?

i dont really trust jessops advice, as they generally try to sell you their most expensive product.

Linear and Circular Polarizing filters both have the same effect, but most metering and focussing systems on SLR's (inc Digial SLRs) won't work properly with a linear one, so you'll need to buy a circular one. Make sure that you can adjust it (ie. turn it round) so that you can see the effect, be it to make the sky darker, or remove reflections. You don't want one that just screws into the front element of the camera as it will be almost useless. I use one from Cokin, from their professional range - because they're bigger than the amateur range, and if you start trying to use a wide angle lens, you'll need a big one

The filter does not affect all areas of the image the same - As Toady says you need to be able to rotate a polarising filter to gain the effect you want - so you should always buy one that 'floats' freely when mounted to the lens - essentially you need to compose your shot then rotate the filter to get the effect (deeper sky for instance) than you would get without the filter - as you rotate the filter you will see your composition change subtly - when you like what you see then then take the shot.

Note - you do get ones that 'screw in' but also 'float' once attached to the lens. That luminous landscape link above probably explains all this better...

Polarisers are one of the best filters to use on a camera, they cut down refelection by altering light paths, so you can cut down sparkle on water for example, they will also lose you f stops of light so a shot which would be say 1/500 secs at f8 with out a ploariser may be 1/125 at f8 with one so you may need to use a tripod, get em right and the effect can be brill, get it wrong and it will look like everyone else who usd to use Velvia to photograpgh a lone tree in a field of oilseed, if you know what I mean
