RAW data
Unedited image data output from the CMOS sensor. RAW data is data
before being internally processed by the camera. Camera settings at the
time of capture, such as White Balance, Contrast, Saturation, and
Sharpness can be set for each frame after shooting. In addition, RAW data
is 14 bit data that contain 64 times the information of 8 bit JPEG 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.
Shutter Speed
The length of time that the shutter is open and light strikes the CMOS
sensor. The amount of light that strikes the CMOS sensor 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
computer monitors and is also used as the standard color space for Exif.
Vignetting
The picture edges are blackened when part of the light coming from the
subject is blocked by the hood or filter ring, or when the flash is partially
blocked by the lens.
White Balance
While shooting, color temperature is adjusted to match the light source so
that the subject appears to have the correct color.
