Shallow depth of field, cool, grey balanced and warm versions.

This is a photograph that employs a 'shallow depth of field'

Depth of field is a section of an image that is acceptably sharp, the rest of the image will be at different ranges of focus (from slightly blurred to very blurred).

.

Depth of field is affected by camera type, lens, aperture and distance between the camera and the subject.

.

'Shallow' depth of field is a very small area of acceptable sharpness within an image. Using a wide aperture gives a shallow depth of field.

For this photo I used a 'close up +4' filter on a CAnon 18-55mm lens @ 18mm. I shot at f3.5 and 1/80 sec, using a flashgun to light my shot.

This is an example of how depth of field works.
