This study takes light modeling as its core entry point to explore its application path and practical value as an aesthetic catalyst in enhancing film and television photographers' awareness of sustainable visual aesthetics. By analyzing the impact of light type, properties, direction, and color on image composition, emotional transmission, and audience psychology, the study systematically integrates light modeling knowledge into the film and television photography teaching system. Using case studies and qualitative research methods, two sets of controlled experiments were conducted to analyze the mechanisms by which different light combinations affect the visual effects and aesthetic perception of images, verifying the actual effectiveness of light modeling instruction in improving students' sustainable visual aesthetic abilities. The study proposes four major teaching strategies: transforming teaching concepts, strengthening the control of lighting atmosphere, simplifying the use of lighting equipment, and flexibly applying the color temperature of light sources. These strategies provide new methods and means for innovation in film and television photography teaching, helping educational institutions to achieve the synergistic cultivation of aesthetic appreciation and narrative function in film and television images, ultimately promoting the formation of sustainable visual aesthetic awareness among photographers.
