This was also my first attempt at using my new polarizing filter for my camera, and it was something of a learning experience. I wanted it for darkening the blue in the sky and for bringing out stronger colors in the flowers, and it did this... but it also gave everything a very "yellow" cast. I accidentally left my white balance on "auto" instead of putting it to daylight, and I think my camera was trying to over-compensate for the polarizer's effect.
When I opened the files in my computer, it was strange to see the pretty colors of the tulips, green grass and blue sky turn into sickly shades of yellow and brown. I had to do some color correcting to bring back the blue hues, but even then, there's something a little "off" about my photos.
Here's an example: everything looks deep and colorful in this photo (the polarizer gave everything a crazy amount of saturation!), but the weird white balance gives everything an almost ominous look, as if a storm is brewing.
At any rate, I learned my lesson, and hopefully the next sunny day will bring out some more experimentation! One nice bonus about bringing the polarizer was that I got some good shots of Mt Hood, which otherwise would have been a washed-out white mountain on an overly bright washed out sky. The polarizer perfectly distinguished between white mountain and blue sky.
Anyone have any polarizer tips to share?
(P.S.- check out my photos from last year's Tulip Festival to see more flower beautifulness!)
