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.

What happens when the diaphragm is adjusted to the largest opening?
You will get the smallest depth of field.
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.
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 does F1.7 mean in photography?
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.
What is shallow depth of field?
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.
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.
How do you photograph a donkey?
Depends on which end. (LOL) Seriously, you want to close down the aperture for an increased depth of field since the donkey being photographed is rather large and you want to keep all of it in focus.
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.
What is the difference between field sketching and photograph?
For a photograph you need a camera for a sketch you need a pad and pencil
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 is Comparison of armature controlled and field controlled DC servo motor?
Difference between field controlled and armature controlled is that field control is open loop and armature current is closed loop.
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.
How does focusing affect depth of field?
The closer the object is to the camera, the shorter the "focal distance". The depth of field gets shallower as the focal length decreases, up until the lens has reached its minimum focusing distance (closer than that and the image will be blurry). If you photograph something at F1.8 that is 5 feet away, your depth of field (area in focus) might be 3 feet (1.5 feet each side of focal point), where if you took a shot at F1.8 but 30 feet away from your subject, the depth of field could be 20 feet (10 feet each side of focal point). I've made up these numbers, but there are charts you can use to calculate DoF based on focal length and aperture.
