Useful Information Regarding Florida Keys Aerial Photography

By Timothy Butler


Within the field of photography, there is a very important one known as aerial photography. Aerial photography is also called airborne imagery. This refers to the process of taking pictures from flying objects like an aircraft or a drone. Among the platforms which are used currently in taking the shots are rockets, kites, UAVs, helicopters, balloons, pigeons and parachutes among others. This is what Florida Keys aerial photography is all about.

The photos may be taken by a person aboard the various airborne platforms. However, if the platform cannot be boarded by a human being, then the cameras used are triggered automatically or remotely. Airborne imagery and air to air photography are two different ideas because of the manner in which photos in the two concepts are taken. In air-to-air imagery, photos of airborne platforms such as aircrafts, rockets, balloons among others are taken by another airborne platform.

Photos captured from the air can be grouped in different classes depending on various factors. Photos which are captured from an angle are called oblique pictures. Low oblique photographs is a term that refers to oblique photos which are taken from a low attitude relative to the earth surface. Alternatively, the term high or steep oblique pictures is used to refer to photographs which are captured from a high angle.

Vertical photos is another group of photographs. These pictures are taken straight down. Normally, these kinds of photos are taken to be used in photogrammetry and image interpretation. Special huge format cameras are normally used to take photos that are utilized in photogrammetry. Such cameras normally have documented and calibrated geometric settings.

Vertical photographs find use in the creation of orthophotos. Another name used to refer to orthophotos is orthophotomaps. These are photographs that have been geometrically corrected so that they can be used as maps. A better way of looking at orthophotos is a simulation of photos captured from an infinite distance, looking straight down. Perspective is usually removed in these photos while differences in terrain are corrected.

Aerial imaging is a field which has a long historical background, starting in France. The very first individual to try out the concept of taking pictures from above was called Gaspard-Felix Tournachon. Tournachon was both a photographer and a balloonist. Owing to his profession, Tournachon chose to take images of the floor of the earth from the air. Cameras used by Tournachon were hooked up on balloons which were flown over Paris.

Taking aerial photographs as an idea proceeded to become popular when World War I started. Britons as well as the Germans used planes belonging to perform surveillance of troops of their enemies. The photos captured then were only in black and white. This made them low quality. Additionally, because they used cameras that did not have enough power, there was a limit in the altitude at which the pictures could be taken.

Today, airborne imagery is a fully developed field. It finds use in very many industries, including the military, research, aeronautical, film making, music, and recreation among others. Equipment used today is better and safer as well.
