No, this doesn't mean photographs of car antennas. What it does mean is taking photos from above, perhaps from an airplane, balloon or helicopter, etc. Aerial photography has been around for about 150 years and is often used in land-use planning, environmental studies, military and espionage, among other things. There are different ways to take aerial photos. You can simply use the same camera you use on the ground, or you can use a complex, pilot-controlled electronic system.
Aerial cameras are either made for handheld use or for fixed installation in photo-configured aircraft. The best camera for handheld aerial shots is usually the one you are the most familiar and comfortable with, however there are some ideal hand-held 70mm aerial cameras on the market.
Aerial film is made for high altitude photography, but it doesn't give you better photos than regular film at low altitudes. Most handheld photography is taken at low altitudes. If using film you need to decide on black and white or color and then if you want prints or slides. You must also take into consideration weather and haze conditions along with lighting. Black and white infrared film is better than panchromatic film as it gives higher contrast and can gather more detail through haze than the human eye. It is ideal for extreme distances such as high-altitude photography. If you use black and white infrared film you must filter out blue and ultraviolet radiation with a red filter. Color infrared is also good. Speed rating for aerial film is called aerial film speed (AFS). Aerial film speed shouldn't be confused with ISO, as they are not equivalent.
