polarizing filters seem to come up in question a lot, especially in the beginners place because they are filters that seem to become part of everyones kit, and it is one of the few filters that cant be replicated by software. I want to make an ongoing thread that shows the impact of polarizers firsthand so that everyone can see what all the hype is about. For these shots I simply held the filter in front of me to get the effect I wanted and then hand held shot the picture. notice in the first picture that the filter obviously produces a slightly darker image. This is because of the filter itself being gray, requiring about a stop extra light to produce the same exposure as a bare lens (meaning it is a weak neutral density filter). For the second picture, I rotated the filter so it would polarize the light from my monitor. Here are my results: normal: polarized: I'll be adding more pictures to show changes in contrast as well as reflection reduction later. Anyone who has or would like to take pictures showing the effect, do so here!
