252 Dynamic Range (D-Range) Indicated with a value expressing the light level reproducible in an image. This is the same as the term "Exposure latitude" used with silver halide film. Generally, when the dynamic range is wide, it is difficult for bright and dark areas to be recorded in the image, and when the dynamic range is narrow, a sharp image can be obtained. EV (Exposure Value) Exposure value is determined by the combination of the aperture value and the shutter speed. EV Compensation Process of adjusting the image brightness by changing the shutter speed and/or aperture value. Exif (Exchangeable image file format for digital still camera) A standard digital camera file format established by the Japan Electronics and Information Technology Industries Association (JEITA). Focus point Position in the viewfinder that determines focus. In this camera, select from [Auto], [Select] and [Center]. Histogram A graph that shows the darkest and brightest points in an image. The horizontal axis represents the brightness and the vertical axis represents the number of pixels. This is useful when you wish to refer to the exposure status of an image. ISO Sensitivity The level of sensitivity to light. With a high sensitivity, images can be shot with a high shutter speed even in dark places, reducing camera shake. However, images with high sensitivity are more susceptible to noise. 12 JPEG An image compression method. In this camera, select from C (Best), D (Better), or E (Good). Images recorded in JPEG format are suited for viewing on your PC or for attaching to e-mail. Appendix
