Image Size / File Quality Options
Standard Test Scene
The SD9 / SD10 digital SLR's don't provide in-camera JPEG
or TIFF, instead the camera captures only RAW data and stores this in
Foveon's X3F file format (which is losslessly compressed, a bit like Zip).
The other big advantage of RAW is that the camera doesn't have to do any
image processing and also becomes easier to use. The X3F files themselves
contain the RAW data straight from the sensor, 36 bits per pixel (12-bits
per Red, Green, Blue).
Despite its lack of JPEG or TIFF in-camera you can select from three different resolutions to be stored in the X3F RAW file. These are 2268 x 1512, 1512 x 1008 and 1134 x 756.
Crops below are of the same 240x100 area of each image nearest neighbour magnified 200%.
Photo Pro Adjustments: None

With the advent of Photo Pro 2.0 Foveon has improved the quality of JPEG output and as you can see from the crops above they are both very sharp and clean with no visible artifacts.
No more in-camera controls
Normally at this point in the review we would explore other in-camera controls such as saturation, tone, sharpness etc. In the case of the SD10 all of these controls are instead available in the Photo Pro RAW conversion application not in-camera. The only other setting which can be applied at the time of taking the shot is white balance, and of course even this can be changed later.
