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 first 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 flash, 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 Reflex (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 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 used because of its richer colour expression over sRGB. 154 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 specific 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 subject. For example, select a smaller aperture to increase the depth of field or use a larger aperture to decrease the depth of field. DNG RAW file DNG (Digital Negative) is a general-purpose RAW file 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.
