The theme of the Jeju Nature Film Festival is the greatness and beauty of nature. The reason for choosing Jeju Island in South Korea is because Jeju is known for its preservation to the extent that it has been selected for three UNESCO designations and is a UNESCO global geopark. This festival aims to allow people to think about the importance of nature once more. The shape of the columnar joint inspired me, so I used its shape as a grid for visual identity.
