This court seems to me to be overly concerned with the "intent" aspect of copyright law as it applies to PHOTOGRAPHER commercial protections. What they have missed, IMO, is the "intent" as it applies to CONSUMER protections.
We, as consumers, should have a registration database to consult to see if works are registered. Isn't that the underlying purpose . . . to put us as consumers on notice that work(s) are registered? As a minimum, we should be able to easily identify registered works using a photographer's name. And, although probably an unrealistic expectation, image recognition software would be better applied to database searches available to consumers rather than after the fact to extort them.
Letting them plead "its in the collection" even though there's no way on earth an "offender" could have known is just unacceptable IMO, no matter how long they've "been doing it that way".
