My E10 saves in TIF and JPG. I haven't used TIF because of the file size. They save at 10MB, and the JPG at about 800KB. The TIF is uncompressed.

Saving the data from the sensor (raw) is available in the Canon 20D. You would have to look at specific camera. For the 20D, it is a camera program setting to save in the raw format. Otherwise, the raw data gets processed to JPG.

It is a camera function, if available, not an application. An application is used to read and modify the sensor data.

I think I saw something in PSP about raw files, too. I have other applications that may have that capability, also. This is new to me, and I have been reading about the capability.
