Ricoh 170543 用户手册

The camera supports the following picture qualities:
• 

Normal: JPEG compression is used to reduce file size.

• 

Fine: Compression rate is low to achieve high picture quality. File 
size becomes larger comparing to Normal quality.

• 

RAW: RAW image data are saved in DNG format; JPEG copies 
are also created. The camera displays only the JPEG copy; 
DNG files can be viewed and edited on a computer using the 
supplied Irodio Photo & Video Studio Software (Windows only) 
or commercially-available applications that support the DNG 
format.

Unlike normal- and fine-quality images, RAW images are not 
compressed. This increases file size but avoids the loss of quality 
associated with JPEG compression. Note the following when 
shooting RAW images:
•  Some functions of the shooting menu are not available for 

shooting RAW images. See the description of each setting for 
details. Image Settings and Date Imprint options apply only 
to JPEG copies and have no effect on the DNG files.

•  The number of RAW photographs that can be taken in a single 

burst in continuous mode differs depending on the camera unit 
and the settings of shooting menu.
