Glossary<br />
Compression rate<br />
Compression is a method of reducing file size by abbreviating some contents of<br />
data, and compression rate denotes the amount of compression. The actual effect<br />
of the selected compression rate could vary with the content of the image. The<br />
numbers for the compression rate selected with this camera provide only a<br />
general scale for reference and are not precise measurements.<br />
Conventional Photograph<br />
This refers to recording images using silver halide (the method for recording<br />
images in conventional, non-digital photography). This system is in contrast to still<br />
video and digital photography.<br />
DCF (Design rule for Camera File system)<br />
A standard for image files by the Japan Electronics and Information Technology<br />
Industries Association (JEITA).<br />
Depth of Field<br />
Depth of Field refers to the distance from the nearest to the furthest point of<br />
perceived "sharp" focus in a picture.<br />
Digital ESP (Electro-Selective Pattern) Light Metering<br />
This determines the exposure by metering and calculating the light levels in the<br />
center and other areas of the image separately.<br />
DPOF (Digital Print Order Format)<br />
This is for saving desired print settings on digital cameras. By entering which<br />
images to print and the number of copies of each, the user can easily have the<br />
desired images printed by a printer or print lab that supports the DPOF format.<br />
Eclipsing (Vignetting)<br />
This refers to when an object obscures part of the field of view so that the whole<br />
subject is not photographed. Vignetting also refers to when the image seen<br />
through the viewfinder does not exactly match the image shot through the<br />
objective lens, so the photographed image includes objects not seen through the<br />
viewfinder. In addition, vignetting can occur when an incorrect lens hood is used,<br />
causing shadowing to appear in the corners of the image.<br />
EV (Exposure Value)<br />
A system for measuring exposure. EV0 is when the aperture is at F1 and the<br />
shutter speed is 1 second. The EV then increases by 1 each time the aperture<br />
increases by one F stop or the shutter speed increases by one increment. EV can<br />
also be used to indicate brightness and ISO settings.<br />
