| data
Unedited image data output from the CCD. RAW data is data before being
internally processed by the camera. Camera settings at the time of
capture, such as White Balance, Contrast, Saturation, Tone, Color Space,
Sensitivity and Sharpness, are also stored but not applied to the image. In
addition, RAW data is 12 bit data that contains 16 times the information of
8 bit JPEG and TIFF data. Rich gradations are possible. Transfer RAW
data to your computer and use the provided software to create image data
with different settings, such as JPEG or TIFF.
Recorded Pixels
Indicates the size of the image by the number of pixels. The more pixels
that compose a picture, the larger the image size.
Sensitivity
The degree of light. With a high sensitivity, images can be shot with a
high shutter speed even in dark places, reducing camera shake.
However, images with high sensitivity are more susceptible to noise.
Shutter Speed
The length of time that the shutter is open and light strikes the CCD. The
amount of light that strikes the CCD can be changed by altering the shutter
speed.
sRGB (standard RGB)
International standard of color space established by the IEC (International
Electrotechnical Commission). This is defined from color space for PC
monitors and is also used as the standard color space for Exif.
Vignetting
Vignetting occurs when corners of pictures are blackened because the
subject was blocked by the hood or filter or the flash was blocked.
White Balance
While shooting, color temperature is adjusted to match the light source so
that the subject appears to have correct color.
