The choice of film is at issue as well. TMax has a truer color rendition than, say, Tri-X. Tri-X is more sensitive to blue light, therefore a yellow filter would be appropriate for darkening the sky value, bringing the scene more in line to how the human eye percieves it. That having been said (written), I still prefer TriX film for almost all of my photography. And yes, I use filters of all types, depending upon how I want the scene to appear in my photograph (aka "previsualization").
