Polarizer play

Took advantage of a sunny-but-not-roasting-hot afternoon to go outside and play with the polarizing filter I bought a little while ago. I haven't used it too much because I just keep forgetting to pack it along with me. So I wandered up the block to the ponds, set up the camera on the tripod and started to play.

First, without any filter. Pointed the camera down the street at a lone cloud in the sky, with the sun mostly to my left.

Then put the polarizer on and turned it to get the minimum amount of polarization. The image is a little darker because the filter does have a little bit of tint to it.

Turned the polarizer 90° to get the maximum amount of polarization. The effect is quite dramatic. The sky gets much darker and really makes the cloud pop out. The greens really come through too and the colours look more saturated.

Next I zoomed in on the clouds down by the horizon. First with no filter

Then with the filter on and turned to minimum polarizing. The clouds look pretty flat and boring, and don't really stand out at all.

Turning the filter 90 degrees really makes things pop out.

Will definitely have to remember to keep the polarizer with me.
