I am thoroughly confused by the numerous suggestions that a circ polarizer will solve the OP’s question. A circ polo is often an indispensable part of my landscape kit, but not for balancing the bright/dark areas of a composition.

I’ll add that graduated nd filters used to be an often used tool in my landscape arsenal, despite the difficulty with the straight line graduation when shooting scenes where the delineation between bright/dark is not straight. But with the evolution of digital imaging and post processing, I never carry the nd grads with me. All of the negatives about those filters (straight line, expense, static electricity making keeping them clean a pain, fragility, etc) are solved by really quite simple post processing procedures. Easy peasy - better results with none of the fussing.

I used to take great pride (especially in the days of film) in my ability to balance differing bright/ dark scenes. Today, a newb can watch a 20 minute You Tube video and produce a better result in PS than I could ever achieve using my resin grads.
