It is depth of field (the part of the overall image that appears acceptably sharp) that doesn't extend very far throughout any portion of the distance from the near and far points in the image. By this definition, the limited depth of field can be in the foreground, middle ground or background, but it is a small portion of the image overall. The average person would find their depth of field to be in the near 1/3 of the distance from the near and far points.
Distance to the subject, lens focal length an aperture are the main controlling factors, but the size of the reproduced image and the distance between the viewer and the image contribute also. Your perception of the depth of field can change as you approach a large image such as a poster in a mall.

∙ 14y agoLonger focal lengths produce less depth of field than short ones. If you search, you will probably find sites that claim the difference is negligible in most cases. It seems they think that (for example) the perception that a telephoto lens has much less depth of field is due to how that lens compresses the same distance into a smaller area of the print. In other words, the distance is the same, it just looks to be less. I think that if you compare the distance scale of a long and short lens, referring to the same aperture and focus distance, the scale will show the wide angle lens has way more depth of field than a telephoto. I would side with the lens manufacturer in the hope they know what they're doing.

What happens when the diaphragm is adjusted to the largest opening?
You will get the smallest depth of field.
The depth of field in a photograph is controlled by the?
Depth of field on a camera is controlled by the aperture. The aperture is basically the size of the opening in the lens. A large aperture (or opening) creates a shallower depth of field and a small aperture creates a greater depth of field. Aperture, along with shutter speed, determine how much light goes into the camera. The size of the aperture is indicated by the f/stop number. The numbers usually range from about f/1 to around f/64. The smaller the number is, the larger the aperture is and the shallower the depth of field, meaning less space is in focus.Additional AnswerDepth of field is also affected by the focal length of your camera's lens. For any given aperture, longer focal length lenses (telephoto lenses) have a much narrower depth of field than a standard lens, and shorter focal length lenses (wide-angle lenses) have a much wider depth of field than a standard lens.
If you are changing the shutter speed why is the depth of field being affected?
Usually, one would change the aperture to compensate for the change in shutter speed in order to keep the level of exposure the same. Changing the aperture affects the depth of field.
Name the advantage of a scanner over a digital camera?
Scanners are capable of making 1:1 images, with a great deal more detail than a camera. The disadvantages are very shallow depth of field, inability to image things away from the scanner surface, huge file size and, of course, limited portability.
What is the difference between the terms 'long take' and 'deep focus' in photography?
I think your question could be re-phrased as the difference between long exposure photography and deep depth of field photography. A long exposure is where a long exposure time is used, either to record movement over a period of time, for artistic effect, or in order to provide a greater depth of field, (deep focus), achieved by using a smaller 'F' number on the camera, which provides a smaller aperture for the light to pass through. ********* For some, it relates to what is technically known as hyperfocal distance (a point of focus deduced and utilized to maximize depth of field beyond normal). IMHO, "deep focus" is a mis-nomer as you can only focus on one plane within the field of view. Anything in front or behind is not in focus; however, it may be acceptably sharp to the eye. This is depth of field. There is also "depth of focus", which is different, though related. Methinks neither depth of field nor depth of focus should be referred to as deep focus
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 camera mode is best for shallow depth of field photography?
Manual or Aperture Priority.
How shallow can depth of field be in macro photography?
With a 100mm macro lens, as little as a few millimeters, even when stopped down to F16.
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 is depth of field important in studying biological structures?
Well the depth of field is very important while studying biological structures because most of the times you'll be examining species that can be very very tiny, so it's needed in order to see a up-close image of the specimen A shallow plane of depth you can only see one plane of your speciman.
What word is the adjective for depth?
Deep is the adjective related to the word depth. A depth may be described as shallow or considerable.
Why is water greater at a greater depth than at a shallow depth?
Because of the weight of the water above.
Is shallow an adjective?
Yes, "shallow" is an adjective. It is used to describe something that has little depth, significance, or understanding. For example, a shallow lake, a shallow person, or a shallow conversation.

Can you get a shallow depth of field with a digital point and shoot You should be able to if it has an aperture setting and or manual or does it depend on the lens?
If you set your camera to aperture priority (usually the "A" on the program dial) and select a large aperture, say, f2 to f4, then the resulting image will have less depth of field than at, say, f11. The lens always affects how wide you can open the aperture, but the depth of field is not dependant on the lens other than this.
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.
