It controls the amount of light that reaches the film.
The diaphragm is a muscle that lies beneath the lungs and above the abdomen. It functions by contracting and expanding the lungs and thereby drawing air into the lungs. When the diaphragm relaxes, air is expelled from the lungs.
Yes it does, only no air is supplied because it is in amniotic fluid. The lungs and the diaphragm function during fetal development in order to prepare for breathing air after birth. During the time in the uterus, the gas exchange is done by the mother through the umbilical cord and her lungs.
Deep diaphragm breathing is done by contracting the diaphragm.
It creates a partial vacuum (region of lower pressure) in your thorax (chest area) to draw air into the lungs (inspiration). When the air has exchanged some of the oxygen for carbon dioxide, the diaphragm pushes the air out (exhalation). So the simple answer is "breathing".
Backwards... The diaphragm is superior to the stomach
A camera's diaphragm and your eye's iris perform the same function in the same way. They both control how much light is allowed through the lens by expanding and contracting.
Limits the amount of light and changes the depth of focus.
The diaphragm is used to change the aperture diameter,same as shade.
the iris
function of rotary camera
It is identical in action to the iris in your eye, it widens and narrows to allow only the required amount of light through the aperture hole/pupil
Allows people to breath
to hold the light
