Oh, I had come across that site when I was searching sources to help someone understand how ISO works on DSLRs and Clark's article seemed logical, and then I clicked on the next... He claims that post-2008 Canons do not need dark/light/bias frames as they have "on sensor dark current suppression" and the RAW converter will take care of the rest! He has nice examples and everything.
Well, I guess my 2011 Canon (600D) is a dud, since it still needs darks...

Also, I can't find the preset "80ED with TRF-2008 reducer, camera rotated 138 degrees, some dust specs" on the RAW converter lens tab to avoid the flats...

Seriously, where did he find that "dark current suppression" thing, he seems to be the only source!
