depth of focus
depth of field

The depth of focus seemed to shift; light years expanded around me.

In modern systems, the depth of focus is also a concern:

The focus spread is related to the depth of focus.

Depth of focus can have two slightly different meanings.

With the second definition, focus spread and depth of focus are the same.

He'd forgotten how it was to see with a depth of focus, without glasses, with young eyes!

Amphibians have colour vision and depth of focus for clear sight.

This method limits the depth of focus somewhat, however, and images in the background are sometimes distorted.

A tilt lens can be used, in the opposite way to that used to increase depth of focus.

Then Rez leaned forward, recognizable in the new depth of focus.

They allow colour vision and depth of focus.

With the first definition, focus spread and depth of focus are usually close in value though conceptually different.

In depth of focus, almost no exhibition based solely on a museum's holdings can match a large-scale loan show.

By taking a through focal series, the depth of focus can be reconstructed to create a single image entirely in focus.

Advantages include increased depth of focus, significant increases in data collection speed, and superior signal to noise ratios.

Do not use T-stops for depth of focus determination.)

Both depth of field and depth of focus increase with smaller apertures.

The reason for improved depth of focus in conventional lenses is linked to residual spherical aberration.

Film and video differ a lot in image clarity, depth of focus and color range, but the biggest contrast is frame rate.

In seismology, the depth of focus refers to the depth at which an earthquake occurs.

How about being able to change the depth of focus AFTER taking the picture.

'For 100 years movies have made us believe that they can control space, with lenses, camera movements, depth of focus - a thousand tricks.

The distance between these two points is called the confocal parameter or depth of focus of the beam:

He readjusts the focus and bumps down the magnification to 40x, sharpening his depth of focus.

It may contribute to the depth perception in natural retinal images, because the depth of focus of the human eye is limited.

For one, it had much less depth of field than I was used to with my 50.

Put another way, it's the place to focus on if you want to get the most depth of field in your picture.

Maybe the depth of field you might argue is not as deep.

And the more light you let in, the shorter the depth of field.

Because the scene is always shifting, the more depth of field the better.

What intrigued her, she said, "was trying to make a book with a depth of field that you could look into."

This provides control over focus, depth of field, and perspective.

You're suddenly given a depth of field not possible before."

See the Depth of field article for a more detailed discussion.

The depth of field may change, depending on what conditions are compared.

There are other times when depth of field, not motion, is the most important consideration.

The camera also has a similar light range and depth of field to film cameras.

In a small room, glass reflects light and appears to give depth of field to a wall.

This gives it a great depth of field, and everything is maintained in focus.

I like depth of field, but can get none with my iPhone 4.

Stops down to f/22 for additional depth of field control.

Depth of field is also governed by the format size.

Very low working distance and extremely shallow depth of field.

That would give them the depth of field they would need.

With standard equipment, you don't have as much control, not nearly the depth of field.

No, this thing is only good for fixing missed focus with short depth of field.

"Steve" told me the camera had been set to have an exceptional depth of field.

Then I began using an extraordinarily shallow depth of field, so only the eyes are in focus.

Depth of field is extremely small when focusing on close objects.

This results in less control over depth of field, compared to larger formats.
