so there you go.. they do things like that.

more info on them here: http://dpfwiw.com/filters.htm#polarizers
 
look mostly at the windows, in all of them. but yeah - the colours change on the yaris.

they're good for shots with sky in as well, but i've not had chance to try that yet
 
Daylight is polarised and then it is further polarised when reflected. You would expect to be able to "tune out" relections and you can see some very nice examples here. The Yaris windscreen is lot more saturated and you can see into the cafe despite the daylight hitting it at greater than the Brewster angle.
I have filters for the old SLR outfit but not the Fuji, this does make you think about buying some. Not sure you could get these effects through photoshop esp where reflections have drowned out transmitted light. Great post:) and to match the subject:cool:
 
thanks. like i say, i spent a while trying to work out what they did - and thought it'd would've been useful to have comparisons to explain it to me, hence taking some.

all shots taken with a fuji s5600 with a jessops 55mm CFP from on the end of the lens.
 
An Ai A or B polariser used to be a standard fit on lenses. They were once desrcibed as "transparent lens caps. " I've got those plus a rotating circular one and a starburst for the Pentax outfit. The polarisers give a darker background in the sky and much more contrast in the clouds. A yellow filter does the same for monochrome The circular one lets you do tricks like looking at a pond and twirling it until you can get an image of the fish.
 
A polariser is a very useful tool for removing reflections. Expecialy when shooting cars. You can remove the reflections of sky etc from the bodywork and windows to give a much nicer look.

They tend to give sky a much deeper blue and as already said, add contrast to the clouds to make them stand out. They tend to only work on the sky when shooting away from or directly across the sun. They will not work towards the sun, or atleast nowhere near as effectivly.

Thats a pic I took a while back using a circular polariser. Notice the transparent windows and gorgeous sky :D Take it off and the sky would probably have appeared more over exposed to compensate for the shadows on the car.
