Polarizing filters are cheap but yet so important. They are simple to use, yet pretty hard to explain. I do my best to show you a few examples, and hopefully it’s helpful. To use them you simply turn the filter around until the image looks good.
A polarizing filter will ‘correct’ the image in a way that cannot be adjusted or fixed in post processing. Forget Photoshop, camera picture styles, shutter speeds, aperture, or ISO settings. You can’t fix what you didn’t capture.
