Most (or I should say a lot of photographers) know that a circular polarizer is used to help darken (i.e. saturate) a blue sky on a sunny day when the sun is at a 90deg angle to you. Fewer seem to understand (or know) that it can also be used to reduce/remove glare/reflections in windows and water even when the sun is at your back. Look at the 2 photos below;
Notice the glare and the water color difference between the 2 images. The 1 on the left is essentially unpolarized. The 1 on the right is using the polarizer and you can see that not only is the water clearer, it is also more true to the actual color. The sun was directly at my back for the shots. The polarizer was turned until the greatest amount of glare/reflection was removed. This also works with building windows.
So the next time you are out, remember, just because the sun is at your back does not mean you can’t use a circular polarizer (well not for the sky anyway). Give it a try on your architectural shots/water shots and see if it doesnt make a difference.
