Aerial photography is a photography style that involves the taking of pictures of the ground from an elevated point. The elevated point can be an aircraft, a drone, a balloon or a rocket. In most cases, one requires a highly-accurate and powerful camera in order to capture great images. In order to identify the differences that distinguish two images of the same area, one will have to look at some factors. These factors include the scale, overlap and the type of film. Under aerial photographs, there are different types of photographs. Oblique photographs are those taken at an angle while vertical photographs are taken straight down. Similarly, there are wide shots and close-up photos, depending on the width of the covered area as well as the distance from the camera. There are also aerial photographs that combine the different styles. Aerial photographs are often used in movie production, developing maps, archeology and environmental studies.
