The Power of Perspective

General goal for a great landscape photo: visual depth
As a photographer, you have one chance to capture the three-dimensional beauty that you see in one flat frozen view.
In a photo, obviously, objects closer to the lens appear larger than those off in the distance, but it it important that you take advantage of this "size cue." By offering images that people have seen before, it allows them to establish a size scale for ovjects in the rest of the photograph.
Size cue examples: trees, shrubs, flowers, bushes, animals
Focal length is important to creating a visual depth in a photo.
For the most extreme perspective effect you should put the camera as close to one of the size cues as possible.
Find the perfect height while avoiding getting too low or too high, because both will flatten your picture. Tim Fitzharris likes to position his camera at a 45 degree angle from the horizon of the first size cue he finds. Avoid overlapping size cues because they will detract. (however, there is an exception)
If the size cues are similar, for example, repetitive rocks, overlapping may cause a neat perspective.
Sidelight can also cause a visual appeal in that it many times displays volume. Sidelight generally causes well lit areas as well as dark shadowed areas, which are easlily distinguished to the viewer. These drastic contrasts also depict depth along with textures too.
Hazy days or otherwise known as atmospherics, days with haze, fog, mist, snow, rain, and dust, help to create three dimensions in landscapes. "A little haze goes a long way in creating perspective effects."
Five planes
1. The foreground plane features plane features interesting land-scape details that set the scale for the composition.
2. the midground plane contains well-defined size cues that lead the ey into the picture.
3. the feature plane shows the center of interest, usually a dramativ landform.
4. the cloud plane is ideally a puffy collection of cumulus or nimbus.
5. and the sky plane comprises the final backdrop in pure shades of blue, rose, peach or amber, depending on the time of day.
