> Because the subjective part of filters can't be proven or disproven.

Not true.  If I can come up with hard numbers, I can then show under what
circumstances any degradation CAN be perceived.

> Its more "do you like chocolate or vanilla ice cream?"

Yes, but you can visually tell the difference, and they do both taste
different.  With the filters, if I show you two images, one with, and one
without, unless you can tell me which one is which, most every time, then
it's all in your mind.

After his first round of testing is done, I am game to do a second round of
double blind perception tests.  I'll cross that bridge when I get there...
