If you are going top try your hand at landscape photography, this is one of the rare occasions that I recommend that you use a tripod.
This will enable you to use your lowest iso setting (better quality) slow shutter speed and your smallest aperture (more things in focus).
Also, try taking some landscapes in the early morning or late evening light to get a more atmospheric image.
