depths of Field means The range of distance along the axis of an optical instrument which the object will produce a relatively distinct image
lacking depth; superficial
Qualitative research is a Field of inquiring applicable to many disciplines and subject mater. - Qualitative researchers aim to gather in depth understanding of human behavior - aQualitative method investigates the why and how of decision making.
It is usually a linear measure in the downward direction.
Today, all pronounciable three-letter abbreviations usually mean several different things. In my "world", DOF stands for Degrees-Of-Freedom. Used for instance to describe how a factory robot can manipulate a work item.
3D means that the picture or movie has depth. Like, it looks like the picture is jumping out at you. 2D is like a drawing on a piece of paper. It has no depth.
Depth of field is the depth of the specimen clearly in focus and is greater at lower magnifications.
As the magnification increases, the depth of field decreases.
Depth of field is best demonstrated with a slide containing overlapping threads. The depth of field that would increase is the low power objective.
No its actually the opposite
The depth of field decreases.
The higher the magnification the lower the depth of field.
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.
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.
The term "wide depth of field" is not used. Depth of field can either be shallow or deep. The definition of depth of field is this: Depth of field is defined as the range of object distances within which objects are imaged with acceptable sharpness. A shallow depth of field would mean that only objects within a small distance in a scene would be focused; everything else would be out-of-focus. For an example, consider many portrait photos; in them the background is blurred while the person is in sharp focus. A deep depth of field would mean that a much larger range of objects at various distances would be in focus. Most landscape photographs are a good example of this.
The f-number is indicative of aperture. The smaller the number, the larger the aperture is, and the more light is let in. The Depth-of-Field is also reduced with a smaller f-number. f/1.7 is a very large aperture, and there will be little depth of field, but lots of brightness.
Depth of field in reference to eyeglasses is the preferred reading distance and its smaller surrounding area. This is the distance used for single vision readers.
Possibly by 'field' you mean a category or type, such as Photojournalism, or Portrait, or Wedding photography. Or maybe you refer to 'depth of field', which is the distance front to back in focus. Sorry to be vague, I have worked in photography for many years, and have never considered the idea of 'field' as such.
