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, overexposed and/or underexposed areas are less likely to occur within the image, and when the dynamic range is narrow, all image tones can be reproduced sharply and accurately.

EV (Exposure Value)

Exposure value is determined by a 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).

Exposure Bracketing

For automatically changing exposure. When the shutter release button is pressed, three images are captured. The first one has no compensation, the second is underexposed and the third is over-exposed.

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 check the exposure level 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 taken with a high sensitivity are more susceptible to noise.
