Why small-format aerial photography? This question is often posed to us by people who work on the ground as well as those who analyze conventional aerial photographs and satellite images. Why indeed? The authors did not start their small-format aerial photography (SFAP) careers as dedicated kite flyers, hot-air blimp developers, UAV fans, or do-it-yourself gadget builders. We have become aerial photographers out of necessity, because we needed to assess landscapes, forms, and distribution patterns in detail and document their changes through time.We required a feasible, cost-effective method that would adapt to the size of the features, the transitory nature of their occurrence, and the speed of their development, and which would yield the best possible spatial and temporal resolutions for the respective research questions. Suitable conventional photographs and satellite images were either inappropriate or unavailable. Self-made aerial photographs offer the researcher a maximum of flexibility in fieldwork. Within the technical limits of the camera and platform, the photographer may determine not only place and time but also viewing angle, image coverage, and exposure settings. While imagery acquired from external sources may or may not show the study site at the required scale, time and angle, such tailormade photos show exactly those sites and features we seek.
