Hi
I have used color flat, bias and dark frames from a Canon D60
digital SLR to calibrate its 12-bit raw images. The following images
is an example of a color flat and dark frame calibrated image from the
D60:

Processing Summary
0) Convert all 3072x2048 flat, dark, and raw images from Canon 12-bit color
raw to 48-bit TIF format.
All images were taken at ISO 800. The steps below were applied to the
converted 48-bit TIF images.
1) Average 5 color flat frames to create a master flat
2) Average 8 - 60 second color dark frames take to create a
master dark
3) Calibrate 8 - 60 second images of M13 using the color master flat
and dark
4) Register the 8 calibrated 3072x2048 images of M13 and then average
combine them.
5) Apply DDP to the averaged color image of M13
6) Apply a slight noise reduction filter to the image
The above link is the result of this processing.
