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 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).

 

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 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

Appendix

with a high shutter speed even in dark places, reducing camera shake.

 

 

However, images taken with a high sensitivity are more susceptible to

 

noise.
