Lim began climbing in 1988, when he entered Hankuk University of Foreign Studies, and learned photography in Japan. In 2008, he became the first Asian to be awarded at the Trento Film Festival with his documentary The Wall. Alpinist was selected as the Ulju Summit film at the first Ulju Mountain Film Festival, where it was screened. He was also a special director for the Korean film The Himalayas. Korea is pretty much barren when it comes to mountain films, but Lim climbed mountains with a camera for the last 30 years, coming to represent Korean mountain film directors. He was with Kim Chang-ho and the Korean Way Gurja Himal expedition that perished in 2018.
