aperture size

The aperture size controls how much light enters the camera.

This concept is also used in photography when changing the aperture size.

Around 1880, photographers realized that aperture size affected depth of field.

Both of them are related to aperture size.

But as aperture size and consequent viewing capacity increase, so does the weight of the telescope.

The ratio of the aperture size to the imaging depth is known as the F-number.

The internal volume of the shell, shell weight, and aperture size are all important.

The standard 0.048 mm aperture size derives from a drill bit used by an employee of Kodak.

The area coverage rate (measured in area per unit time) is proportional to system power and aperture size.

It does not consider aperture size.

Aperture size - the size of the aperture of the gate.

One of the unique features of drum scanners is the ability to control sample area and aperture size independently.

Still, these physical controls are intuitive and satisfying; they teach you about the relationship between shutter speed and aperture size better than any menu could.

The laser beam profiler's effective aperture size is three orders of magnitude smaller than that of an iris.

(The manuals for both cameras are very good, but they exist solely to explain how to adjust, say, aperture size or shutter speed.

Depth of field (not to be confused with depth of focus) is determined by the aperture size and the focal distance.

In combination with variation of shutter speed, the aperture size will regulate the film's or image sensor's degree of exposure to light.

Aperture sizes are usually referred to as f/stops, a technical term that refers to the ratio of a lens's effective diameter to its focal length.

This reduces the effective aperture size by an amount proportional to the deposited material, leading ultimately to aperture clogging.

The degree of soft-focus effect is determined by either aperture size or special disks that fit into the lens to modify the aperture shape.

This method reduces the aperture size of the antenna and achieves a higher degree of electrical stability in the presence of the human body.

Power beaming by microwaves has the difficulty that for most space applications the required aperture sizes are very large due to diffraction limiting antenna directionality.

With anastigmat image quality achieved, attention next turned to increasing aperture size to allow photography in lower light or with faster shutter speeds.

The minimum resolution (d) for the optical component are thus limited by its aperture size, and expressed by the Rayleigh criterion:

It has an aperture efficiency of 1.0 so it gives the maximum gain and minimum beamwidth for a given aperture size.
