In my landscape photography, I work with the yellow or red filter, mainly to highlight some clouds or increase contrast in the final image. Normally I do not use the polarizing filter on my pictures, unless I want to remove the reflections in the water, and sometimes if I want to further darken the sky. A few days ago, my wife gave me polarized glasses. They really are very useful for driving. But what I want to emphasize is that with them I can see the sky and mountains with greater clarity and detail. Having said that, should I use the polarizing filter more often? Thanks for your comments, Henry.
