Is a good film class worth buying?

I attended the late class of 19, and I feel that this is the most effective and correct learning channel for learning photography in recent years. The design of the whole course includes the concept of photography, the use of equipment, aesthetic concepts, human body structure, the theory and relationship between light, shadow and color, the use of various PS tools, the formulation of shooting plans, the analysis of pictures from an aesthetic point of view, and then the process of artistic re-creation with the knowledge learned. Every teacher, with his rich experience, tries his best to teach and solve doubts, and the wonderful courses and knowledge explosion are enough to meet the interests and requirements of students at different levels. Thanks for meeting the tutors and friends of the Institute of Light and Shadow on the road of photography, including Wen Zi, Akin, Guo Jia, Azhe, July and Nangong, the head teacher. Thank you for your patient guidance. Living in America, I often accidentally ask for advice at the wrong time. Thank you for your tolerance.
