Thank you @greddyforce! Yes, the graduated neutral density filters are great for landscape photography. I currently use the Lee filter system which is not cheap... For many years, I used a less expensive filter holder and filters and they got the job done just fine. However, with the Lee system I can use a polarizing filter along with the graduated ND if I want to. The Lee filters are supposedly better quality too so I technically should have sharper photos when printed huge.
