Kodak DCS Pro SLR/n User Manual

Your camera can save images as Raw or JPEG files.
Raw (.dcr) files can be opened by KODAK PROFESSIONAL DCS Photo 
Desk. Raw images can be thought of as "digital negatives." They preserve all 
image information so you can apply the DCS-specific image enhancements 
available in DCS Photo Desk.
JPEG (.jpg) files are smaller and can be opened directly by any image 
editing software. You can choose ERI (Extended Range Imaging) JPEG or 
Standard JPEG (see 

). 

NOTE:  Repeated saves of any JPEG image can degrade image quality.

When you use one memory card, you can specify that captured images are 
saved to the card as Raw, JPEG, or Raw+JPEG. (With Raw+JPEG, both file 
types are written to the card.)
When you use two cards, you can specify that one card is standby or that 
captured images are saved to both cards as Raw, JPEG, or Raw+JPEG. 
When one card is set to standby, no images are written to that card until the 
other card is full. When the other card is full, subsequently captured 
images are written to the standby card using the same file type. When 
neither card is standby, captured images are written to both cards. (You 
can write different file types to two cards, for example, Raw to one card and 
JPEG to the other.) 
The following table provides examples of some ways to set up file types:
