AF |
Auto Focus |
When you let the camera decide when the subject is in focus. Depending on the focusing system of your camera and lens this could be quite fast or slow if the lens decides to hunt around to try and lock onto a subject |
Aperture |
|
The hole in the lens that controls how much light gets to the sensor/film while the shutter is open - Smaller number = bigger hole, bigger number = smaller hole... Refer to this article in wikipedia |
BIF |
Bird/Bee In Flight |

BG |
Background |
|
bokeh |
Blury background |
From wikipedia: is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as "the way the lens renders out-of-focus points of light". |

CC |
Construstive critique /
Comments and Critique (usually written as C&C) |
When someone provides you with their idea on how you could improve your photograph. Photography can be very subjective so what someone says may not agree with what you think. This is ok, you are not expected to take on the critique of anyone who comments on your photos. After all it is only someone else's opinion, and they do not have all the contextual details about your photo, so it is entirely up to you whether you take on board the critique. |
CPL |
Circular Polarizing Filter |
|
DOF |
Depth of Field |
That part of a photograph that is acceptably sharp. (Controlled by Aperture) |
ETTL |
Expose Through the Lens or Expose to the Left |
|
ETTR |
Expose to the Right |
|
GND |
Graduated Neutral Density filter |
A neutral density filter that filters different amounts of light across different parts of the filter. Useful for reducing dynamic range of a scene, e.g. when you need to balance exposure between the sky and the foreground. |
HDR |
High Dynamic Range |
|
IQ |
Image Quality |
Use of this term has no relation to anyone's intelligence... |
ISO |
International Standards Organization - digital camera's (or film's) light-sensitivity |
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to measure the sensitivity of digital imaging systems. See this linkin wikipedia for more details |
MF |
Manual focus |
When you don't let the camera do the focusing and you manually try to get the optics to focus on your subject by turning the focus ring |
ND |
Neutral Density Filter |
A filter that cuts down on the amount of light entering the lens. The use of an ND filter allows for slower shutter speed and/or larger aperture when lighting conditions would normally be too bright for the settings you want. |
OOF |
Out of focus |
Usually when referring to a part of an image that is not in focus (not necessarily the main subject) e.g "The OOF tree on the right is distracting..." |
