New to Landscape photography - Pointers please

hey people, been into photogaphy for a while now, but only recently upgraded to an slr (canon 350D). got myself a ND Grad filter,tripod n remote shutter release but looking for suggestions on what other gear wud help to improve my shots

The GND filter is probably the most valuable tool for landscape photography. I have both a hard and soft edge one. Be sure it's true ND and not a "gray" grad. I hope you have a rectangular one that fits in a holder on the front of the lens. That way you can position it as you need to. The circular ones put the transition across the middle and you cant move it.You can also stack them if needed. Be sure to get a CLP (polarizer) filter also. You can get one to fit your largest diameter lens and get step down rings to fit you other lenses. There is also a CLP that will fit in the holders I mentioned before.
