Medium and Large Format Cameras :)

Large and medium format usually means bigger photographic films or sensors. Most large format cameras have adjustable backs and fronts and extreme camera movements unlike anything today. These movements allow the photographer to have total control in the overall perspective and depth of field of the chosen image.
Large format cameras are generally used by architectural and close-up photographers, but they can also be good for nature fine art, and landscape photography as well.
There are a lot of pros and cons with large format cameras.
