Medium format refers to a type of film or digital camera system that uses a larger image sensor or film size than standard 35mm formats. Typically, medium format cameras have sensors that measure around 6x4.5 cm to 6x9 cm, resulting in higher resolution and better image quality. This format is popular among professional photographers for its ability to capture fine details and produce images with a distinct depth of field. Due to the larger size, medium format cameras are often bulkier and more expensive than their smaller counterparts. They are commonly used in portrait photography, landscape photography, and commercial photography, where image quality is paramount. Many renowned photographers, such as Richard Avedon and Ansel Adams, have utilized medium format to achieve stunning visual results.
