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.

2 types of camera shutters?
There are more than two, for sure. I know of the focal plane shutter (a pair of horizontally or vertically traveling blinds near the film plane), the leaf shutter (usually 1 to 3 blades contained within the lens that pivot to uncover the opening) and the diaphragm shutter (3 to 5 blades that pivot in such a way as to create a roughly circular opening much the same way as the aperture blades in a SLR lens). I believe the term "central shutter" is used to describe the position of what is usually a diaphragm shutter as opposed to being a type on it's own. The earliest and simplest shutter was, in fact, the lens cap itself. The two basic types of shutters are the Focal plane shutter and the Leaf shutter.
Opening in a wall to let air or light in?
An opening in a wall to let in air or light is called a window.
Which part of a microscope can be adjusted to allow light in?
The diaphragm or iris can be adjusted to regulate the amount of light entering the microscope. By opening or closing the diaphragm, you can control the brightness and contrast of the specimen being viewed.
What controls the aperture in a camera?
The aperture in a camera is controlled by the diaphragm, which is a mechanism that can be adjusted to change the size of the opening through which light enters the camera.
What is the name of the opening where the esophagus pass through the diaphragm?
The opening where the esophagus passes through the diaphragm is called the esophageal hiatus or esophageal opening in the diaphragm.
What is adjusted purchase?
the term adjusted purchase means the purchase value adjusted with opening stock and closing stock. i.e.- adjusted purchase= opening stock+purchases-closing stock Jitendra Kumar Nath 7418738372
Aperture?
Opening of the lens diaphragm through which light passes
What Controls the amount of light entering the microscope adjust what part?
The diaphragm controls the amount of light entering the microscope. It is usually located beneath the stage of the microscope and can be adjusted to regulate the intensity of light passing through the specimen. By opening or closing the diaphragm, you can control the amount of light that reaches the specimen, which can help improve image quality and clarity.
What happens when you change the diaphragm openings in a microscope?
Changing the diaphragm openings in a microscope adjusts the amount of light entering the lens system. A smaller opening increases contrast and depth of field, while a larger opening allows more light in, potentially sacrificing some contrast. Adjusting the diaphragm can help optimize image quality for different specimens or magnifications.
What happens when you move the iris diaphragm level while observing the field?
Adjusting the iris diaphragm level while observing the field of view can change the amount of light entering the microscope. Opening the diaphragm lets in more light, while closing it reduces the amount of light. This can affect the brightness and contrast of the image being viewed.
What does diaphragm mean in terms of a science dictionary all about telescopes?
A diaphragm in optics, including telescopes, is a thin opaque structure with a central opening.
The opening that transmits the esophagus from the thoracic to the abdominal cavity?
esophageal hiatus of the diaphragm
What is The structure that regulates the size of the opening for light in and is similar to a camera diaphragm?
iris
How does a diaphragm prevent pregnancy?
it keeps sperm from going to the eggThe diaphragm prevents pregnancy by preventing the sperm from fusing with the egg or by blocking the opening to the uterus.
