A major advantage of a pinhole over a simple (or not so simple) lens is "infinite depth of field." To see this for yourself poke a pinhole into a thin sheet of opaque material and hold the pinhole close to your eye (if you wear glasses, take them off). Hold one of your fingers a few inches in front of the pinhole and notice that your finger is about the same clarity as everything else beyond. That's infinite depth of field. A more or less scientific explanation for depth of field is that an optical image is made of of very tiny "circles of confusion." When the circles of confusion are small enough, they are called "points" and the optical image is considered to be in focus. Therefore, points of focus. A pinhole camera has infinite depth of field because the pinhole creates circles of confusion the same size as the pinhole all over the inside of the camera, and the little circles of confusion are small enough to be regarded as points of focus. These have a high enough resolution to be acceptable as a coherent image. Photographers can use a small aperture to increase the depth of field, but except for rather uncommon lenses, the depth of field is not very extensive compared to a pinhole image.

What is the maximum depth of field in photography?
Infinite, with a suitable lens. In theory, a pinhole camera (which has no lens at all) will have a nearly infinite depth of field, but at the expense of extremely long exposure time.
How does the size of the hole in pinhole camera effect the quality of the image?
In a pinhole camera, the size of the hole has the same effect as the aperture setting on a more traditional camera. The size of the hole, combined with its distance from the film or sensor, controls the depth of field of the image and the length of exposure needed. Smaller holes will result in greater depth of field (to a point) and longer exposure. To compare a pinhole camera to a traditional camera, the distance from the film to the pinhole gives you the focal length, the size of the pinhole divided by the distance to the film gives you the effective aperture which can be used to determine the exposure needed. The reason that I included the "to a point" when discussing depth of field is that the pinhole must be in a very thin material and should be blackened in order to limit loss of sharpness due to diffraction. Diffraction also contributors to a loss of sharpness in traditional lenses when stopped down past f16 or so.

What is the difference between pinhole camera and camera?
Pinhole was a slang term for A. a primitive type of camera with a very small aperture, giving maximum depth- but requiring much light, and B. this still in use- the smallest , and thus the deepest in depth of field aperture of any given camera or lens. My most modern Nikon F-80 has a preselected F/32 pinhole setting ( coded in as M) on the modal dial) this is great for distance shots of skyscrapers and the like on bright days only! Photo sensors will shift to a brighter aperture if there is anadequate light- such is progress. l25 ( shutter speed) and F-32 can work wonders with buildings.
Does a Nikon D90 camera have depth of field preview?
yes
What camera mode is best for shallow depth of field photography?
Manual or Aperture Priority.
Why do pinhole cameras need long exposure times?
Because the aperture is tiny, so as to take advantage of the depth of field a small aperture will give. This lets pinhole cameras make sharp pictures without needing any way to focus them.
What happens to the size of the image if the object is moved closer to the lens of a camera?
The size of the image has no relevance to how close or far a lens is from its target, regardless if the camera is digital or not. If the camera is set to save images at 800x600, it will still be 800x600 no matter where the lens is focused.
What does F5 camera setting mean?
the F numbers usually refer to the aperture of the lens which controls how much light can enter the camera. it also affects the depth of field.
Why is the depth of field greater and the image sharper when a camera lens is stopped down to a larger f-number?
See the answer to "Why do you get a greater depth of field from a smaller aperture"There's also a great article on it at: http://www.uscoles.com/depthoffield.html
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.
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.
