What does the diaphragm mean in photography?
The diaphragm, often called the "iris" diaphragm for its identical form and function to the iris in your eye, regulates the physical amount of light allowed to pass through a camera lens. It may be called the "iris," the "diaphragm," the "iris diaphragm," the "stop," or the "aperture." All mean the same thing.Physically, the diaphragm or iris diaphragm is made up of overlapping thin opaque metal plates, usually six or eight, which can be adjusted to increase or decrease the diameter of the hole, called the stop, in the center of the lens. The diaphragm is often located at the optical center of the lens between sets of elements. On manual cameras there is usually a ring around the lens barrel marked in f/stops for adjustment of the diaphragm.The iris (diaphragm) in your eye, working properly, automatically opens or closes in response to light level. When you are exposed to strong light the iris closes down (or "stops" down) to a smaller diameter, decreasing the light reaching your retina (equivalent to the film or sensor in your camera). In dim light, the iris opens up to admit more light. The diaphragm in your camera works the same way, and on modern cameras it's often equally automatic. You may never even notice it's working.In a camera, the iris diaphragm and the shutter have to work together to control the total exposure. The iris diaphragm controls the amount of light, and the shutter controls the amount of light over time. Depending on the make and model of the camera, shutter and diaphragm may be manual, automatic or both. The diaphragm is the mechanism that varies the size of the aperture; the opening that allows light into the camera.

What does the iris of the human eye do?
The iris helps blot out the excess light.
What kind of tropism is a iris?
Iris grows towards the light. That is phototropism.
Which part of the human eye controls how much light enters?
The iris controls the amount of light entering the eye by adjusting the size of the pupil. In bright light, the iris contracts, making the pupil smaller to reduce the amount of light. In dim light, the iris expands, making the pupil larger to allow more light to enter.
What part of eye makes the pupil smaller in bright light and larger in dim light?
The iris is the part of the eye that controls the size of the pupil. In bright light, the iris constricts the pupil to reduce the amount of light entering the eye, while in dim light, the iris dilates the pupil to allow more light to enter and improve vision in low-light conditions.
The pigmented muscular structure that allows light to pass through is the?
iris
What controls the amount of light reaching the retina?
The iris controls the amount of light reaching the retina by adjusting the size of the pupil. In bright light, the iris contracts to make the pupil smaller, reducing the amount of light that enters the eye. In low light, the iris expands to dilate the pupil, allowing more light to enter the eye.
What happens to the iris to allow less light to enter the eye?
The iris contracts to allow less light to enter the eye. This is controlled by the autonomic nervous system in response to changing light conditions, helping to regulate the amount of light reaching the retina.
How does a microscope iris diaphragm lever work like the iris of an eye?
The iris diaphragm adjusts the amount of light allowed in.
