IDENTIFIKASI BIOTA GUA MENGGUNAKAN FOTOGRAFI DENGAN TEKNIK HIGH KEY

Abstract

Identification of Cave Biota Using High Key Technique Photography. Photography is recording reflected images produced from objects illuminated by light through a device called a camera. According to Ben, (Ben Brain 2012) Photography using the high key technique is a photo that is dominated by white. High key has a function to simplify the background, making the observation/identification process easier. Cave biota is important to discuss because it functions as an indicator of biodiversity and ecosystem balance in caves. According to Cahyo (Cahyo R. 2021) Cave biota experiences physiological and morphological adaptations due to having to survive in the unique conditions and environment of caves. These forms of adaptation are regressive and progressive. Progressive adaptations include: eyes that become smaller or disappear altogether, loss of body pigment, loss of wings in several groups of insects; regressive adaptations in the form of: elongated antenne or legs and increased sense of taste such as the number and/or fine hairs on the surface of the body, trichobothria. This journal discusses how to carry out practical photography that will be used as a medium for identifying biota, including the techniques used, equipment and methods. The methods for this research were collecting cave’s biota samples, conducting photography practice, and making identification. Then, photos of cave biota were identified using a determination book and described according to the taxonomy of each type.
