From the camera obscura in the era dominated by painters to the photography in the 19th century, people have been trying to capture the chemical reactions of different “lights”. Nowadays, the element “light” has transformed into digital image. Such fission process has not only greatly extended the boundaries of photography concept, but has also gradually infiltrated the construction of other media forms and modern life and turned into an aesthetic experience for sharing and exchange. From bulky cameras to portable digital devices, from complicated photographic processing to ready-to-use print technology, from the distribution of physical photos to the sharing of electronic photos, from the two-dimensional pictures to three-dimensional and moving images….the development of technology has not only affected our way of life, but also changed the way of watching. In line with the curatorial ideas and exhibited works of Guangzhou Image Triennial, we selected three key words—“watch”, “capture” and “disseminate”—as the theme of the public education event of the exhibition. In the meantime, we developed diversified navigation means and a series of educational activities for the public, such as Visit the Exhibition Together, Art Museum Courses, Workshop for Artistic Experience, online interaction and so on.
