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 are 12 bit data that contain 16 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.

 

Sensitivity

 

The level of sensitivity to 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 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

10

subject is blocked by the hood or filter ring, or when the flash is partially

blocked by the lens.

Appendix

White Balance

While shooting, color temperature is adjusted to match the light source so that the subject appears to have correct color.
