Does a Nikon D90 camera have depth of field preview?
yes
Can you take a bokeh picture with a Nikon d40x?
Generally, you can with all cameras. All you need is a shallow depth of field. You can achieve this by using a low aperture (ex. f/2.8, f/1.8) The lower the f/#, the shallower your depth of field will be.
Why the lever mirror lockup stuk in Nikon f4 camera?
You have to press the depth of field button to release/enable the mirror lockup. While pressing the depth of field preview button rotate the mirror lockup lever clounter clockwise until it stops.
What is the depth of field on a microscope?
Depth of field is the depth of the specimen clearly in focus and is greater at lower magnifications.
What happens to the depth of field as the magnification increases?
As the magnification increases, the depth of field decreases.
What is depth of field best demonstrated with?
Depth of field is best demonstrated with a slide containing overlapping threads. The depth of field that would increase is the low power objective.
Is the depth of field on a dissecting microscope less than the depth of field on a compound microscope?
No its actually the opposite
Does the depth of field increase or decrease when one moves to a higher magnification on a microscope?
The depth of field decreases.
What happend to the depth of field if magnification increases?
The higher the magnification the lower the depth of field.
What happens to the depth of field as your move from low power to high power?
Depth of field decreases from low to high. This means what you see under the microscope is blurry. If both objects are not blurry, this means you have high depth-of-field.
What is the difference between maximum depth of field and shallow depth of field on a camera?
Depth of field in photography is 3-dimensional and is measured from the foreground moving along a horizontal plane towards the background. Maximum depth-of-field means most of the scene is in focus and shallow depth-of-field means the minimum is in focus. Shallow depth-of-field lets you lose the background into a nice blur leaving the foreground in focus - good for portrait photography. In landscape photography you would normally choose the maximum depth-of-field so that distant hills were in focus as well as the middle ground and the foreground - in other words, everything in the field of your vision would be sharply focussed.
What is z depth pass?
It is an image/image sequence rendered from a 3d animation program for compositing with other types of 3d image layers in a post processing program. It allows the person doing the post processing to adjust the camera focus/depth of field of an image or image sequence.
