This document summarizes a study that investigated using digital camera simulation media to improve students' understanding of key photography concepts. The study was conducted over two cycles with 47 students. Results from pre-testing found students averaged 40.1% understanding. After the first cycle using simulations, the average increased to 68.55%. The second cycle extended simulation time, which further increased understanding, with students averaging 83.57%. The study concluded that digital camera simulations are effective for improving students' comprehension of concepts like aperture, shutter speed, and ISO.
