@Mork: if you shoot upwards of f11+ or whatever you can get away with without causing diffraction then this is what you want to get depth of field. You don't want a shallow depth of field if you are shooting landscapes. You do want a shallow depth of field if you are trying to focus the attention of the viewer on something within that landscape such as a model. Although the use of an off camera strobe might better serve your purpose than to blur out the scenery.
But also, as in the above photo, landscapes are generally better if you follow one or more of the rules of good photos such as the rule of thirds, anchoring, etc. Here is an example:

As another example I shot some trees recently that would look just "blah" as a regular pic ... I post processed by turning the pic's canvas askew and dropped tones down except for green:

Here is another shot at F/11 ... instead of taking a plain old building pic of this abandoned building, I decided to capture a little more interest by kneeling all the way down and getting some of the overgrown grass in the field around it - Which further communicates "abandoned"
