oblique photographs

A type of aerial photography in which the camera axis is deliberately kept tilted from the vertical by a specified angle. The photographs, thus taken, reveal details masked in some ways in vertical photographs. The main function of this type of photograph is intelligence; these photographs cannot be used for mapmaking because of their large-scale errors. There are two types of oblique photographs: (i) high oblique—one in which the apparent horizon appears—and (ii) low oblique—one in which the apparent horizon does not appear. See aerial photography, low oblique, and high oblique.

Short notes on Oblique photographs

• A vertical photo is one that was taken with the camera axis pointed as vertically toward the ground as possible, whereas an oblique photo was taken with the camera axis pointed at an angle to the ground.
• Oblique aerial photography has the primary benefit of allowing for the most opportune angle of capture, which enhances interpretation. They are simple to comprehend.
• A image that purposely deviates from the vertical but not far enough to include the horizon in the exposure is referred to as low-oblique photography.
• According to the vantage point or location from which they were taken, photographs are categorised. They can be obtained from the air or the ground. This essentially leaves us with three different types of photographs: horizontal, oblique, and vertical.
• The most typical sort of aerial photograph used for remote sensing and aerial surveying is vertical. They can be scaled, allowing measurements of items and distances, which helps with identification. Vertical images can reveal information about the height or vertical features of landmarks and structures when seen in stereo.
