Dynamic 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).
Exif stands for Exchangeable Image File Format. This image file format is based on the JPEG image data format, and allows thumbnail images and image properties to be embedded into the data. Software that does not support this format processes the image as a regular JPEG image.
Exif stands for Exchangeable Image File Format. This image file format is based on the TIFF image data format, and allows thumbnail images and image properties to be embedded into the data. Software that does not support this format processes the image as a regular TIFF image.
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.
