Introductory Lecture on photography
The document discusses key parts and concepts related to cameras and photography. It describes the shutter speed dial and what shutter speed means, with higher shutter speeds avoiding blur from movement and lower shutter speeds allowing more light in low light conditions. It also discusses the aperture ring and how the f-number relates to the aperture diameter and exposure. Finally, it touches on depth of field and how factors like aperture, focal length, and distance to subject impact the zone of sharp focus.
