Focus Stacking Method （＊）
The technique is to get images that are focused on the entire surface of the subject by synthesizing multiple images by changing the focal depth. It is possible to reconstruct three-dimensional images of the small animals beautifully in high definition.
Dr. KENJI KOHIYAMA Professor Emeritus Keio Univercity / STU LABO
Dr. Kohiyama received his B.E., M.E. and Ph.D. degrees from Keio University in 1965, 1967 and 1976, respectively.
1967 Since he joined NTT in 1967, he has been engaged in the research and development of various radio communication systems, including digital microwave radio relay systems, satellite communication systems and mobile communication systems.
1997 ~ 2007 Professor at the Graduate School of Media and Governance.
2008 Professor Emeritus Keio University.
As well as gaining high reputation in research on digital transmission systems in the NTT Research Division, he has also been active in nature photography, taking butterflies and insects, and has evolved its own territory in insect photography by ultra-fine depth synthesis technology. In addition, we focus on the microscopic functions of small organisms, and present the viewpoint of micro-presence, which approaches evolution and the principle of the universe.
2005 “The 21st Higashikawa New Photographer Prize” for his photo-exhibition “Insects: Micro Presence”at a gallery in Shinjuku, 2004 summer.
2010 “The 41st Koudansha Publishing Culture Award Photographer Prize” for his photobook “ Weevils：Micro Presence”.
( ＊) Insects are beautiful, delicately like excellent crafts. It’s a natural art. By accurately conveying the beauty of the details, it may become a door that invites many people into the precious beautiful world of nature. From such a thought, I started to shoot photographs accurately record the form and the color of the insects. However, the length of insects is a few millimeters in the world. When we take a close-up shot, we focus only on a part from the shallow of the focal depth. It is far from an accurate expression of the entire appearance of the insect. To solve this issue, the insect of about several millimeters to 8 centimeters, and photographed by changing the focal depth of 50 to 200 or more, and cut/synthesize only the part of the focus in the computer and expresses it as an integral insect. I have pursued the expression in this method for thirty years. What is displayed here is a work created by the Focus Stacking Method. (Kenji Kohiyama)
