THE TRIANGLE

ISO, SPEED, DIAPHRAGM

The values contained in this diagram correspond to the sensitivity
(ISO), the aperture of the diaphragm (APERTURE) and shutter

speed (SHUTTER SPEED) and are closely linked to each other.
As the one changes, the others also change in order to have a

correct exposure of the photo.
If we set a low ISO value, the shutter speed will be slower and the

aperture more open, vice versa if the ISO value is high, the shutter
speed will be faster and the aperture will have to be closed.

Depending on our needs, we will set the camera by modifying
these parameters according to the result we want to obtain and
the shooting conditions (hand-held or on a tripod, during the day,

at night, indoors, etc.).
