One of my favourite photos is of the Costasiella Kuroshimae sea slug taken in Tulamben, Bali. Costasiellas are super cute, tiny creatures that resemble sheep and are one of my favourite subjects. Fondly also called Shaun the sheep nudibranch. This photo was published in the Polish edition of National Geographic, together with several other of my photos. That was one of the greatest moment in my photography life. I use the Olympus OM-1, Micro Four Thirds digital Mirrorless camera, in Nauticam housing with INON Z240 strobes. My main lens is Olympus 60 mm macro. The advantage of my setup is its relatively small size. This system provides me with good speed and good-quality photos.
