It is in the lens. It is the bit that opens and closes to allow more or less light through the lens and onto the film/digital sensor.

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 part of your eye is like the diaphragm of a 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
Why is an SLR camera better than the automatic?
SLR or single lens reflex refers to a particular type of camera in which the image and the viewfinder are both taken from one lens. effectively WYSIWYG. auto focus auto exposure modes have been available in SLR cameras for a very long time thus making them "automatic." As a side note an SLR need not have exchangeable lenses to be an SLR nor are all cameras with exchangeable lenses SLR's. The primary advantage of SLR's is the fact that the image in the viewfinder is pretty much the image that you get when you release the shutter.
Who invented autofocus camera?
Minolta No, Minolta were the first to market an autofocus SLR (the 7000) that actually worked. The first AF SLR was the Pentax ME-F, but there were compacts before that.
Who created iris folding?
Iris folding started in Holland.
When would you use the iris diaphragm?
Cameras have an iris diaphragm.
What body part is the same as the iris diaphragm?
The radial and circular muscles of the iris.
How does a microscope iris diaphragm lever work like the iris of an eye?
The iris diaphragm adjusts the amount of light allowed in.
How does closing the iris diaphragm affect image brightness and contrast?
An iris diaphragm controls the amount of light admitted to a lens. Closing the iris diaphragm will decrease the brightness and increase the contrast of an image.
What does the diaphragm do on a micrscope?
On a microscope, the iris diaphragm controls the amount of light.
What is pigmented diaphragm of the eye?
The Iris
Where is the iris diaphragm on a microscope?
This iris diaphragm of a microscope contains the amount of light that can enter through to the specimen. If the condenser iris diaphragm is open, the image will be bright; if it is closed, it will be dim.
Who invented the iris diaphragm?
Robert Hooke
How did the iris diaphragm get its name?
It got its name from its shape. It closes similar to the iris in your eye.
Why should closing the iris diaphragm improve you ability to determine thread order?
By closing the iris diaphragm, it closes the peripheral light so you can get a better image.
What part of the eye is like the diaphragm of a camera?
the iris
What is the function of the iris diaphragm of the mircroscope?
Equipped on the Condenser of the microscope, the iris diaphragm is a shutter controlled by a lever that is used to regulate the amount of light entering the lens system.
