Gelsonlab HSTM-062 Education Science Toys Camera experiment
This Camera Experiment uses the light reflected by the subject to focus through the camera lens (scene lens) and the shutter that controls the exposure amount. After the subject forms a latent image on the photosensitive material in the dark box, it forms a permanent image after processing (i.e. developing and fixing). This technology is called photography. The reflection principle and its application of the solution light are studied through experiments.
