Where did he say that no professional commercial/fashion photographer used Canon?
BUT there is another part in the process that uses the same lower bits as shadow lifting: color reconstruction during debayering. No matter what you do to control contrast or suppress noise in software - color suffers one way or the other.
Well, that's a issue commercial/fashion clients tend to notice, but is all to easy to ignore by the "I put extra thick slices of tomato on my eyes and still can't hear the noise, so it can't be a problem"-fraction.
Thanks for that excellent explanation as to why no professional commercial/fashion photographers – particularly high-profile, successful ones – would ever consider using Canon cameras. Oh, wait...I found who does!
I believe he said that, when they do use Canon, they have a problem which they would have liked to see fixed.
He didn't. He stated that commercial/fashion clients
tend to notice that color suffers, which if true, would mean they would likely be unhappy with images for which they had paid yet had poor color. That's entirely different than a photographer noticing a problem and wanting it fixed, even if the clients don't notice. Someone engaged in a profession who delivers goods their clients consider poor quality would likely not remain successful by continuing to deliver a poor quality product. Connect the dots...if clients notice poor quality, one needs to change/improve or business will suffer. Yet...high-profile, successful photographers continue to remain just that...while continuing to use Canon cameras.
So, once again we have someone claiming a broad, pervasive problem with Canon image quality...a problem which doesn't seem to have affected the success of those photographers using Canon dSLRs.
Oh, and if anyone doesn't
notice a problem with Canon image quality, well...they have thick tomato slices over their eyes and try to hear the noise in their images. Sure.
