Is there a design difference between the 10d and 300d that makes this
removal easier/possible on the 300d? Are there any websites detailing this
hack? Any chance that the hack can be reversable for terrestrial use
(wishful thinking probably :-/).

I have seen the 10d response curves posted, doesn't look good for emmision

Do you know of any objective comparision with and without the filter in
place? I'm waiting for my 10d to arrive, and my wife would probably take a
dim view of me hacking it immediately - need evidence! :)

Cheers, Paul.
