The smaller the aperture, the wider the depth of field.
Additional AnswerDepth of field is also affected by the focal length of the lens. For any given aperture, longer focal lengths (telephoto) have narrower depths of field; shorter focal lengths (wide angle) have wider depths of field.

If you had a very large and very small funnel and cut the straight part off at the bottom, one hole would be larger than the other. Put both of them small end down on a table top. Now you have a representation of the rays of light converging near the film surface (the table top). However, they are not focused exactly to a point because the point of the subject matter they represent is farther away than the part of the subject that is EXACTLY in focus on our imaginary film plane. Let's say the circle size of the small funnel APPEARS to be in focus to the naked eye, whereas the large one is not. The difference in the circle size is a function of the angle or slope of the funnel sides. Similarly, a large aperture produces converging lines like the large funnel, whereas a small aperture will produce converging lines like the sides of the small one. Therefore:
- the smaller the aperture, the more acute the angle of convergence
- the more acceptably sharp non-focused points are
- the more that appears to be in focus that lies in front of or behind what's really in focus
- the greater the depth of field.
If you can't imagine all of the above, note the two angles made by these characters:
angle caused by small aperture: /\ angle caused by large aperture: ^
If these were the funnels and I cut off the same small amount (horizontally) from each, the one on the left would produce a smaller circle of light than the one on the right.

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.
Aperture in a sentence as a noun?
By opening the aperture of the lens, the photographer was able to increase the photo's depth of field.
What is the possible problem with bracketing by changing the aperture?
Changing the depth of field.
What does the aperture dial do on a camera?
The aperture ring changes the lens aperture which controls how much light reaches the film or digital sensor. A large aperture f/1.4 to f/2.8 = lots of light, fast shutter speeds, narrow depth of field A small aperture f/9+ = much less light, slower shutter speeds, wide depth of field
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 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.
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 camera mode is best for shallow depth of field photography?
Manual or Aperture Priority.
How does exposure - aperture affect the quality of a picture?
The smaller the aperture, the more light enters the camera and onto the film. Also, the higher the aperture number the better the depth of field.
What determines the shallowest depth in field in photography?
The largest aperture which is the smallest number on the aperture ring/dial generally anything between f1.2 - f5.6 dependant on the lens and zoom. On most consumer digital cameras the more you zoom in the higher the smallest aperture becomes. eg. Lens at 35mm, widest aperture (shallowest depth of field) generally about f2.8 Zoom in and the largest aperture will reduce to about f5.6
What can you infer about a large aperture?
A large aperture will not only allow you to have a higher shutter speed and to freeze action but also it will give you a narrower depth of field.
Does a telephoto lens give less depth of field than a wide angle lens?
Yes, all other things being equal. The longer the focal length the shallower the depth of field. It also depends on the distance from the lens to the subject and the aperture used to create the photo. For a given lens, the depth of field increases as the subject distance increases. For a given distance, depth of field increases as the aperture gets smaller (e.g. F4 less, F8 more depth).
