| comp., MS | jednostka przysłony | f-stop (In photography, a unit on a scale used on camera lenses to indicate a sequence of f-numbers where each stop corresponds to an f-number and with each stop the light that reaches the film is halved) |
| therm.energ. | przysłona aperturowa | aperture diaphragm |

| comp., MS | wartość przysłony | focal ratio (In photography, the diameter of the aperture expressed in terms of the focal length of the camera lens. The greater the f-number, the less light reaches the film and the more in focus the objects in the foreground and the background will be. For example, with an f-number = 16 the objects in the far background will be in focus. Whereas, with an f-number = 2 the background will be blurry (while foreground objects are in focus)) |
