It has been almost a year since I declared the end of my blogging career and discontinued posting with the one exception of the "Alert" that I did in May. I have been back a few times to visit some of my old blogging friends, and lately I've been missing it, so I've decided to stick my foot back in the door and see if I'm allowed in. I will not be blogging every day and besides simply sharing a few photos I will probably use this blog space to pass on things I learn or have learned about photography and post processing. I may put an occasional tutorial or experiment. Maybe I'll even resurrect Sunset Sunday if there is any interest at all.
Today I'd like to share a little experiment with you dealing with Polarizing filters. If you've ever shopped for a polarizing filter for your digital camera you've probably read or heard that you need a "Circular Polarizer" for digital cameras. I read that before I bought mine and so naturally that is what I bought. The other day I ran across a comment by a fellow photographer that piqued my interest because he asked the question do we really need "Circular Polarizers" or is that just a marketing ploy and "Linear Polarizers" will work just as well. I thought about this and since I wanted to get a "Linear Polarizer" for another purpose that I will share with you another day I ordered one and did some tests. I will leave the conclusions to you.
Note: The Linear Polarizing photos were taken about 5 minutes later than the Circular Polarizing photos and you can see how much the cloud situation had changed.
