The bolt.
The shutter of a camera opens and closes allowing light into the camera, the hole in the shutter is the aperture.
there is no function of the aperture but there is a function of the shutter. the shutter opens and closes to a certain point, allowing light into the camera. The hole in the shutter is the aperture
The aperture of a camera opens and closes to control the amount of light entering through the lens based on the brightness of the subject. By adjusting the size of the aperture, the camera can regulate the exposure of the image and determine the depth of field in the final photograph.
It is called anthesis.
It is called a door closer. The door closer controls the speed at which the door closes to prevent it from slamming shut.
The aperture setting refers to the iris of the camera lens. Like that of your eye, it opens and closes, regulating the amount of light entering the camera body and exposing the film. I always remembered it like this: "The smaller the number (aperture setting), the bigger the hole" and vice versa. If you are in a darker room you need to turn the aperture down to allow more light in so that your prints do not turn out under exposed. You can also adjust your speed setting in correlation with the aperture setting to create greater/less depth of field, meaning what is in or out of focus in front of or behind your subject.
The type of plant that closes when you touch it is called a sensitive plant, also known as Mimosa pudica.
it is called a draw bridge
The aperture is like the iris of the eye. When the aperture is very small, you will get a sharper focus and more depth of field-- near and far things in the scene will tend to be sharper. This is because the smaller circle is cutting down on the "confusion" caused by the countless overlapping circles of light being focused on the film or other light sensitive surface in the camera. The down side is that because the iris is smaller, less light is getting in, and you need a longer exposure to get a good image. When the aperture is larger, you can get a good image with a faster exposure, but sharpness and depth of field may suffer a little. The "circles of confusion" are larger, because the aperture is larger.
It opens /closes heater duct doors and sometimes 4 barrel carburetor secondaries. It is basically a vacuum actuated servo
epiglottis
When you swallow, the larynx moves up slightly, and a flap called the epiglottis closes over the trachea.
