....OP posted photos. Is he supposed to take a photo of each individual pleat in 4KHD so you can digitally enhance them while looking for tears?
Heck, he even pointed out potential failure points on the ADBV. ...
Way better than average photos too.
So we go off on this guy about "science and methodology" for posting a cut open filter, but all kinds of filtered and manipulated data and just flat out wrong "BITOG Truth" goes un-challenged or the posters get insulting if it is, then the thread gets locked down for "bickering".
Unreal.
OP - Thanks for the C&P.
