The document summarizes a photography lesson that taught about aperture, shutter speed, and lighting. It discusses how aperture controls the amount of light let into the lens, with lower settings producing darker photos. Students practiced with plastic toys to focus on small objects. Shutter speed determines the length of time the shutter is open, with higher speeds freezing motion and lower allowing blur. Practicing involved throwing balls and running. Lighting, or ISO, controls the camera's sensitivity to light. Students took photos of each other in a studio using reflectors and lightboxes in different positions.
