Glossary
AdobeRGB
Colour space recommended by Adobe Systems, Inc. for commercial printing. Wider
range of colour reproduction than sRGB. Covers most of the colour range so colours only
available when printed are not lost when editing images from a computer. When image is
opened by non-compatible software, the colours look lighter.
AE Metering
Brightness of subject is measured to determine exposure. In this camera, select from
[Multi-segment Metering], [Centre-weighted Metering] and [Spot Metering].
Aperture
The aperture controls the amount of light that reaches the camera sensor.
Auto Bracket
For automatically changing the shooting conditions. When the shutter button is pressed,
three images are shot. The fi rst one has no compensation, the second is under-exposed
and the third is overexposed.
Camera Shake (Blur)
When the camera moves while the shutter is open, the entire image appears blurred.
This occurs more often when shutter speed is low. Prevent camera shake by raising the
sensitivity, using the fl ash, or by using a faster shutter speed. Alternatively, use a tripod to
stabilize the camera. Because camera motion causes camera shake, use the self-timer,
the remote control unit, and the cable switch to prevent this.
CMOS (Complementary Metal Oxide semi-conductor)
Refers to Complementary metal–oxide–semiconductor (CMOS). It is used in most Digital
Single Lens Refl ex (DSLR) cameras to “convert” light into the camera sensor. The CMOS
sensor is an important feature that determines the quality of digital photos.
Colour space
A defi ned range of colours from the spectrum which are used. In digital cameras, [sRGB]
is defi ned as the standard Colour Space by Exif. In this camera, [AdobeRGB] is also used
because of its richer colour expression over sRGB.
Colour Temperature
This numerically expresses the colour of the light source illuminating the subject. This
is indicated in absolute temperature, using Kelvin (K) units. The colour of light shifts to
a bluish colour as the colour temperature rises, and to a reddish colour as the colour
temperature falls.
DCF (Design rule for Camera File system)
The Design rule for Camera File System was created by the Japan Electronics and
Information Technology Industries Association (JEITA).
DPOF (Digital Print Order Format)
Rules for writing information onto a card with recorded images regarding the specifi c
images and number of copies to be printed. Prints can easily be made by taking images
to a DPOF photo printing store.
Depth of Field
Area of focus. This depends on the aperture, lens focal length, and distance to the sub-
ject. For example, select a smaller aperture to increase the depth of fi eld or use a larger
aperture to decrease the depth of fi eld.
DNG RAW fi le
DNG (Digital Negative) is a general-purpose RAW fi le format designed by Adobe
Systems.
Exposure
Total amount of light allowed to fall on the photographic medium.
Exposure is determined by the combination of the aperture value and the shutter speed.
EV (Exposure Value)
EV steps are numbers which refer to certain combinations of lens aperture and shutter
speed. There is one EV step difference between the aperture stop 4 and 5.6 for example.
EV Compensation
Process of adjusting the image brightness by changing the shutter speed and aperture
value.
