When taking photos there are many angles to explore apart from eye level (neutral level), if you use different angles then its shows variation in the subject in which you are taking a photo of. There are 5 different angles in which you could explore, If you look at the image below it shows the different angles in stages.
The angles all give a different view or perception on the subject depending on the angle used. for instance if the birds eye view is used you would focus on the top of the subject and its surroundings. Here are some examples of my own and an explanation to understand more.
This is a birds eye view, this shows surrounding of a location but with a subject (5 pence).
This type of shot is a high view shot, what this shot does is give authority to the viewer to show powerful and strong views, The image which was taken shows power as the angle is looking over someone, not someone looking over you.
this type of shot is a low view shot this shows detail in both ranges of a subject such as this one, The view of the building is also showing what is surrounding the building by using this shot type.
This type of shot is known as a neutral shot, this shows the perception of the subject directly on eyes point. The view of the image is shown as if this is directly in front of you.
This type of shot is a worms eye shot, this shot expresses the detail as if you was at ground level looking up and out (like a worm) this is another great way to express an images features.
