I read what Gordon said about polarizing filters with his photos from the bolivian altiplano and I remembered that I hadn't tried this filter with my 40D. I used it the last time on my Rebel K2 film camera and the results were variable since the 28-90mm USM had a rotating front element and it was a pain in the neck to make it work.
Today I tested it and here are the results.



ISO 100
1/60 sec
f4 @ 28mm
Aperture priority



ISO 100
1/100 sec
f11 @ 30mm
Aperture priority
Auto levels on both with CS3
No color editing

I really like the first one.

This one too but I'm no sure about the filter if it really worked here.

Ahh naa I don't think it went too well in that photo because i'm guessing the sky wasn't too blue and then when it was blow down in the right hand side it kinda pulled it out to much and it just looks a little odd.

Where was the sun located in relation to view seen in this photo? (I'm assuming that's the moon in view) The polarising effect varies depending on the location of the sun. Luminous-Landscape shows a good way to work out which part of the sky will be most polarised; If you make a gun with your index finger and thumb (so they are at right angles to each other) and then point your index finger at the sun. The area of the sky where your thumb is pointing is the part that will be most polarised. This also applies to the path that your thumb points to when you rotate your wrist through 180 degrees.

This is a view of the NNE part of the city. The sun is in the far left (W) at sun set.
Colors at the far right of the photo were richer than that. For me the image seems washed out and not with the real colors it had.
That's why I'm telling the polarizer didn't work out, it just didn't change the blue in the landscape. What went wrong if the index is pointing left? Not enough sun?

Sometimes poalrising filters can have quite unexpected results, especially after the sun has set - it's not always about making a sky deeper blue...

If the effect isn't a strong as you remember from film days, I'd also recommend shooting in daylight white balance and maybe even applying a little negative EV...

The first shot is really beautiful !!

I really think it's because the filter worked there and the colors are very bright... I'll try to learn some more on the right use of this filter.

I'll do what Gordon advised and publish some results here.

Cheers

I usually rotate my filter to make sure I get the best shot.
