[filmscanners] Raw file format (was: is this about as good asitgets?

["Bob Shomler" <bobf1@shomler.com>]

>By the way, does anybody have any info on Canon's raw format?

I don't specifically; but from other discussions I understand it is the camera 
sensor data (Bayer GRGB [green, red, green, blue]) before Bayer color 
transform, white balance, and alias ("false color filter") processing.  I just 
checked a few 6 megapixel D60 raw files; they are around 6.6 to 8.3 MBytes plus 
~12KB for a separate thumbnail file.  Canon has released a SDK.  There are a 
couple of SW offerings that do raw conversion based on that (I use Breeze 
Browser).
