A circular polarizer is one of those filters that is really worth having. It is great for reducing glare from reflective surfaces. It will pull the glare from wet leaves or the surface of a pond so you can see more detail and color – and it helps cut through haze to enhance the blue in the sky.
The filter is made up of two rotating elements, and seems pretty simple to use… just screw it onto your lens, and then rotate the outer ring until you get the effect you want. At least, that’s what I thought when I first went to Death Valley with my brand new wide-angle lens and my expensive new circular polarizer.
I planned to use my circular polarizer filter to make the most of the complimentary colors – a brilliant blue sky and the golden light on the rippling sand.
But I was in for a surprise. I didn’t really know how my circular polarizer filter worked – and that lack of knowledge ruined every single photo of the Mesquite Dunes.
At first, I was baffled. I thought there must have been something wrong with my camera. But, I did my research, and I discovered that the effect produced by the circular polarizer filter is highly dependent upon the angle of the sun. Shooting with a wide angle lens can cause uneven polarization… which produces a dark “blob” in the sky.
A bit of knowledge would have saved me a lot of money… and a lot of work. I might have come away from that trip to Death Valley with a collection of images I would have been proud of.
You can be sure I was ready when I returned to Death Valley for another try. This time, I knew when to use my filters, and when to leave them in my bag… and my photos show the rich colors and beautiful textures I had originally envisioned.
This is exactly the kind of information you will find in our Essential Filters course. We start out with an in-depth discussion of the different filters that we carry. We explain why we carry them, how they work, and the problems that you might encounter in the field. We’ve included lots of examples for using each type of filter… and we don’t stop there. We follow it up with a variety of real-world case studies so you can see and understand the thought-process behind our on-location workflow. You’ll see the effect of each filter on the backs of our cameras, and you’ll learn as we explain our camera settings and choices in the field.
