Filters have been indispensable tools for photographers since the film era. Even today with the advanced camera technology and post-processing software, filters are still irreplaceable and contribute to the creative process, especially long exposure photography. This course is not just the fundamental knowledge about filters, but also my experience on how to use them creatively to produce outstanding images.
