[General Answer - applies to DSLR & 35mm] The smaller the f-stop value, the smaller the depth of field. In typical "snap-shot" working distances, f2.8 - f4 typically provide small DoF and nicely blurred backgrounds.
BUT - there are a couple of 'Gotchas'
(Examples below assume 35mm film or full frame DSLR)
- Focal length effects DoF
- 24mm lens @ f/4 working 10 ft from subject = DoF 20.9 ft
- 35mm lens @ f/4 working 10 ft from subject = DoF 6.47 ft
- 50mm lens @ f/4 working 10 ft from subject = DoF 2.94 ft
- 100mm lens @ f/4 working 10 ft from subject = DoF .71 ft
- Subject distance effects DoF
- 50mm lens @ f/4 working 20 ft from subject - DoF 12.7 ft
- 50mm lens @ f/4 working 10 ft from subject - DoF 2.94 ft
- 50mm lens @ f/4 working 5 ft from subject - DoF .71 ft
- 50mm lens @ f/4 working 2 ft from subject - DoF .11 ft
Another DoF 'Gotcha'
- The bigger the image sensor, the longer your focal length.
- The smaller the image sensor, the shorter your focal length.
- A typical point a shoot camera will have an actual focal length of 5mm - 35mm
- That provides the same effective viewing angle as a 20mm - 140mm zoom on a full frame DSLR
- Because of the smaller sensor, you must shoot at 24mm instead of 100mm (See 24mm vs 100mm above)

What is wide depth of field?
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.
Does depth have a short vowel sound?
Yes. The E has a short E sound, as in deft and debt.

Short Answer, yes.
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.
