154GlossaryAdobeRGBColour space recommended by Adobe Systems, Inc. for commercial printing. Widerrange of colour reproduction than sRGB. Covers most of the colour range so colours onlyavailable when printed are not lost when editing images from a computer. When image isopened by non-compatible software, the colours look lighter.AE MeteringBrightness of subject is measured to determine exposure. In this camera, select from[Multi-segment Metering], [Centre-weighted Metering] and [Spot Metering].ApertureThe aperture controls the amount of light that reaches the camera sensor.Auto BracketFor automatically changing the shooting conditions. When the shutter button is pressed,three images are shot. The first one has no compensation, the second is under-exposedand 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 thesensitivity, using the flash, or by using a faster shutter speed. Alternatively, use a tripod tostabilize 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 DigitalSingle Lens Reflex (DSLR) cameras to “convert” light into the camera sensor. The CMOSsensor is an important feature that determines the quality of digital photos.Colour spaceA defined range of colours from the spectrum which are used. In digital cameras, [sRGB]is defined as the standard Colour Space by Exif. In this camera, [AdobeRGB] is also usedbecause of its richer colour expression over sRGB.Colour TemperatureThis numerically expresses the colour of the light source illuminating the subject. Thisis indicated in absolute temperature, using Kelvin (K) units. The colour of light shifts toa bluish colour as the colour temperature rises, and to a reddish colour as the colourtemperature falls.DCF (Design rule for Camera File system)The Design rule for Camera File System was created by the Japan Electronics andInformation Technology Industries Association (JEITA).DPOF (Digital Print Order Format)Rules for writing information onto a card with recorded images regarding the specificimages and number of copies to be printed. Prints can easily be made by taking imagesto a DPOF photo printing store.Depth of FieldArea 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 field or use a largeraperture to decrease the depth of field.DNG RAW fileDNG (Digital Negative) is a general-purpose RAW file format designed by AdobeSystems.ExposureTotal 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 shutterspeed. There is one EV step difference between the aperture stop 4 and 5.6 for example.EV CompensationProcess of adjusting the image brightness by changing the shutter speed and aperturevalue.
