I just came across this article that gives 9 points in taking Landscape photos.
Here’s a quick tip taken from the article …
Set the Aperture Value High
Around 22 should give you a nice sharp overall image. Many lenses are the sharpest around 8 but that’s a whole other level of sharpness. Go with as high value as you can get and use a tripod. Unless you are going for effects like freezing the flow of water. Since the shutter speed will be quite slow while shooting landscapes you should set the ISO to around 50 or 100 which will cause low amounts of noise in the picture.
