You can successfully recreate the look of many filters in post-processing, but a polarizer is something you need to have on your camera at the time of capture. I've used the best polarizing filters for decades, mainly for enhancing the colors of landscapes or adding contrast during unavoidable shoots in the midday sun when the vibe is washed out. Circular polarizers are designed to filter out polarized light, and by doing so they reduce or remove reflections from shiny surfaces like water, glass, and metal. They can have a practical as well as creative use case.
Traditionally, you'd buy a circular polarizer, screw it onto the end of your lens thread and then unscrew it when you're finished. This approach isn't complicated, but it can take time – time that might mean you're missing out on moments and other filters. That's where Kenko's Pro1D+ CPL filter comes in.
