As the most fundamental and readily available light source for mobile photography, natural light directly determines the color texture and visual expressiveness of images. Mastering the scientific techniques of natural light color capture is an effective way to enhance the imaging quality and communication value of mobile photography. To establish a systematic and practical training system for natural light color capture in mobile photography, addressing issues such as color deviation and improper lighting application in amateur photography, this article conducts a series of analyses and research on methods for training natural light color capture techniques in mobile photography. The results show that specific training approaches— such as building a theoretical framework, reinforcing practical training, and improving training models—significantly enhance learners' abilities in natural light color recognition, reproduction, and creative application. These methods effectively improve the color accuracy, visual clarity, and artistic expressiveness of mobile photography works, thereby providing a scientific basis and practical reference for the popularization of mobile photography skills and the development of professional training courses.
