Photographers’ gobbledygook can be confusing! This photography dictionary will help you find the real significance behind that jargon.
Wide
A Short focal length lens which takes in a greater angle of view than a standard lens. Depth of field increases as focal length decreases.
(see Focal length, Tele & Standard lens)
Setting the lens aperture to its largest possible opening; for example 24-70mm f2.8 zoom opens to a maximum of f2.8. 'Wide open' creates a shallow depth of field.
(see Aperture, Depth of field, f-stop & Stop down)
White Balance
Depending on the lighting conditions, a pure white in a photograph may appear slightly yellow or blue. The white balance control settings on a "Digital Camera" will help to eliminate unwanted colour bias by actually controlling the camera's colour temperature response. C.C. filters or a specially balanced film must be used when a film camera is utilized under the same lighting conditions!
