Equivalent Exposure & the Exposure Triangle

The 3 camera settings that comprise the Exposure Triangle are shutter speed

& aperture and IOS .

On the back monitor of our Nikon D3400 cameras, the aperture setting is displayed by second circle. Apertures (from smallest openings to largest openings) are typically numbers f2 , f28, f4, f5.6, f8, f11, f16

The shutter speed settings are shown on the 1st circle (1st, 2nd or 3rd from the left) on the back monitor. Expressed as fractions of a second, the shortest or highest shutter speed on our cameras are 1/400 seconds and the longest or slowest shutter speed is 30 seconds.

The third setting iso controls the camera’s sensitivity to light . This setting goes from 100 to 12800 (max) on our cameras.

To set the ISO on our cameras, we hold down

the Fn button an rotate the command dial Set the iso to 400. Then set the aperture to f5.6, by holding down the #4 button on the top of the camera and rotating the Command dial.
