Just one question, and pardon me if I seem impolite: what the hell were you doing using a pinhole on a landscape shot?
Don't get me wrong: pinholes are great fun. They can create really kewl images. But if you're wanting to take a picture of a landscape, and you have a nice piece of glass in the shape of a lens, then that's what you want to use, not a pinhole. Save the pinhole for situations demanding extreme depth of field, soft effects and such.
Sounds as if you're just putting more obstacles in your way than you need to.
