Understanding Exposure Models



A-DEP
ISO- 800
F stop - f/5.6 
shutter speed - 1/30

A-DEP is where the camera selects your shutter speed, and also picks your aperture. You don't have to change your light meeter. The camera assesses the distance between the lens and objects in your frame. 

AV
ISO- 800
F stop - f/4.5
shutter speed - 1/80

AV is the aperture priority exposure. That means that you only pick your aperture and it picks the apporpriate shutter speed. It is the opposite of TV

M
ISO-800
F stop - f/5.0
shutter speed - 1/30

M stands for manual mode, and this is where you get to choose everything. From shutter speed, aperture, ISO and also the light meeter. 

ISO- 800
F stop - f/4.5
shutter speed - 1/50

P is known as programmed exposure, where the camera selects both aperture and shutter speed. You get to choose different combination's of the two though. Along with the camera having an automatic light meeter. 

TV
ISO- 800
F stop - f/8.0
shutter speed - 1/80

TV stands for time value and is shutter priority exposure. This means that you get the choice to choose your shutter speed and the camera chooses the aperture setting.
