Glossary of terms
DPOF (Digital Print Order Format)
This is for saving desired print settings on digital cameras By entering which
images to print and the number of copies of each, the user can easily have
the desired images printed by a printer or print lab that supports the DPOF
format.
Eclipsing (Vignetting)
This refers to when an object obscures part of the field of view so that the
whote subject is not photographed. Vignetting also refers to when the image
seen through the viewflnder does not exactly match the image shot through
the objective lens, so the photographed image includes objects not seen
through the viewfinder. In addition, vignetting can occur when an incorrect
lens hood is used, causing shadowing to appear in the corners of the image
Effective Pixel Resolution
The number of pixels used in the CCD to create the image.
EV (Exposure Value)
A system for measuring exposure EV0 is when the aperture is at F1 and the
shutter speed is 1 second The EV then increases by 1 each time the aperture
increases by one F stop or the shutter speed increases by one increment. EV
can atso be used to indicate brightness and ISO settings.
Exposure
The amount of tight used to capture an image The exposure is determined
by the time the shutter is open (shutter speed) and the amount of light that
passes through the tens (aperture).
Gross Pixel Resolution
The total number of pixels in a CCD Not all pixets are used to create the
image
ISO
A method for indicating film speed by the InternationaI Organization for
Standardization flSO) (e.g. 'qSO100"). Higher ISO values indicate greater
sensitivity to light, so images can be exposed even in tow-light conditions
