I know, you didn't say I was wrong, you wanted to check it out for yourself. (as it should be - so many people take what certain others spout off as gospel without checking themselves...)

And you're right that the whole thing should be wrong.
Have a good one.

carpents:
I tried telling you a while back that it made a difference. I'm glad you figured it out ;)

I'm assuming it must tone down certain channels that are picking up the most light. Really, how would a white balance work? Try to get all 3 channels to register equally, which is why when you do a WB (for normal work) you shoot a gray card, or something equivalent.

So why wouldn't it try to tone down the channels some? I know it's still RAW, and in theory RAW should just record data, and only color balance as an afterthought so the post processing program has a clue what you were doing - but as noted by others it seems to affect the actual data recorded as well, which is why your RAW results using a custom white balance are different.
