Purple Blacks

This may turn out to be academic for just about everyone except those that have bought a Leica M8 or who are thinking of buying one soon. But, for anyone in this category it may well be a viable work-around until such time as Leica is able to provide an appropriative fix.
In case you've missed out on the drama, the new Leica M8 has a weak to nonexistent infrared blocking filter. I saw this and reported on it inmy initial M8 review, and again in aInfrared follow-uppiece.
I had not seen the problem magenta cast issue myself prior to publishing my initial review, except in one image, and in part that's why I didn't report on it then. I didn't understand what I was seeing. That's now a well known story unto itself, which I won't go into here now. The point is that the magenta cast issue has been identified, and Leica has stated that they recognize it and will be taking steps to fix it.
There does seem to be a partial solution available though, and rather than wait for Leica's fix, whateve...
