I originally shared this on the now retired How to Photograph the Canadian Rockies weblog but it has enough value to publish again. The following steps may help you better use Cokin’s Blue/Yellow Polarizing filter.
If you are like me, you bought the Cokin P173 Polarizer and received it in a square plastic casing. You placed this filter into the Cokin-P holder, rotated the polarizer to the desired strength and then found yourself scratching your head because it was now near impossible to add a graduated filter. This limitation alone was a primary reason why my P173 filter found a permanent home in the camera bag. I actually had it listed for sale until I told Darwin Wiggett my frustrations. He happens to know a thing or two about photography and suggested this fantastic solution, but first, let’s pause to talk about today’s photo.
A thin strip of Prince Edward Island coastline intersects two equal halves of the clean and competing colors in the sky and water. In the distance are the sand dunes of Cavendish. I’m not typically a fan of a clear sky but sometimes no clouds can be acceptable and for a very windy location like this, it takes a long 20 second exposure to make even the best of days look calm.
Back to the filter mod.
