equivalent exposure & the exposure triangle

The 3 camera settings that comprise the Exposure Triangle are ISO, Aperture & Shutter speed.

On the back monitor of our Nikon D3400 cameras, the aperture setting is displayed by command circle (1st, 2nd or 3rd from the left). Apertures (from smallest openings to largest openings) are typically numbers f2 , f2.8, 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 f 5.6 of a second, the shortest or highest shutter speed on our cameras are 1 seconds and the longest or slowest shutter speed is 1000 seconds.

The third setting 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.
