in fact, i don't see why it has to be done on the 10D in the article at all
since it should have the same type of NR firmware as the *istD. dark field
subtraction of an image taken immediately afterwards will be slightly
noisier and not as clean as using a dark field from after the sensor has
cooled for a while, but i have not had any noise problems after taking a
succession of 10-20 second exposures at ISO 200 on the *istD.

The Pentax DSLRs will optionally do this for you automatically once the
shutter speed drops below a certain threshold.
