High end lenses will have a constant aperture, such as 2.8 or 4, which means that the relative aperture will stay the same throughout the zoom range.

A device called a diaphragm usually serves as the aperture stop, and controls the aperture.

In this case 1.4 is the maximum aperture (the widest opening), and 22 is the minimum aperture (the smallest opening).

I had to use a very small aperture to get the depth of field.

Lambert, Constant.

To see it, a telescope is required around 30 cm (12 in) aperture being desirable.

These differences include the shape of the nasal aperture and the shape of the mandible.

The material constant in Curie's law is known as the Curie constant.

It's a constant struggle.

Female driver, constant danger.

Similarly, the smaller aperture of Spitzer means that Hubble can add finer spatial information to a Spitzer image.

Zoom lenses typically have a maximum relative aperture (minimum f number) of 2.8 to 6.3 through their range.

The gravitational constant is a physical constant that is difficult to measure with high accuracy.

We get every person doing whatever he wants, with every aperture of every other person and every other animal.

Aperture card mounted microfilm is roughly 3 of the size and space of conventional paper or vellum engineering drawings.

It can be seen that the greater the diameter of the lens or its aperture, the finer the resolution.

The self was not constant.

Fog is also a constant.

Temperatures tend to remain constant.

Measurements under constant pressure produce larger values than those at constant volume because the constant pressure values also include heat energy that is used to do work to expand the substance against the constant pressure as its temperature increases.

A lower f number denotes a greater aperture opening which allows more light to reach the film or image sensor.

γ is the Euler Mascheroni constant.

Temperatures are kept at a constant .

However, this did not contain the constant itself, but simply a list of logarithms calculated from the constant.

And then the aperture closes, and we have to flush the pipes with toxins, or we have to dig them up.

It has an apparent visual magnitude of 11, so a telescope with an aperture of at least 8 cm (3.1 in.

Optimally, the size of the aperture should be 1 100 or less of the distance between it and the projected image.

There is only one narrow aperture, big enough for the male to transfer food to the mother and eventually the chicks.

Different measurements of heat capacity can therefore be performed, most commonly either at constant pressure or at constant volume.

Magnification and demagnification by lenses and other elements can cause a relatively large stop to be the aperture stop for the system.

Refraction in the cornea causes the effective aperture (the entrance pupil in optics parlance) to differ slightly from the physical pupil diameter.

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

And they say, Oh, yeah. Constant acceleration.

A constant may also refer to a constant function or its value (it is a common usage to identify them).
