I just did some research on first sale rights but I'm still unclear as to the ramifications of it and photogs/Copyright trolls trying to get over on people for pics they've already sold.
The First Sale doctrine would not apply to creative works because - even if a photographer would outright "sell" their work to a third party, all that happens is that they transfer all their rights to the work to the buyer... who would then have the full remit of copyright protection under law per the transferred work.
However, the majority of photographers who supply their work to outlets such as newspapers do so by granting them a license that permits the publication to make use of photograph(s) for in a specified manner and duration in return for an agreed fee. This is certainly how I work with my clients.
Also, as Robert has already pointed out, "Fair Use" is not a blanket argument that you can use to absolve yourself of a claim of infringement. If you wish to lodge a defense of Fair Use during trial proceedings, then it would be up to the judge/jury to decide if the use was fair, and the factors to decide it are weighed on a case-by-case basis for each individual image in dispute.
If you were to look at the case known as Cariou vs. Prince (use Google) you'll note that, on appeal, a court found twenty-five of the thirty images in that action were deemed to have met the standards for a Fair Use defence; however, the court remanded the outstanding five images that were not decided on back to a lower court for further consideration; however, before this happened, it was announced that the claim on the remaining images had been settled on undisclosed terms.
I suspect that Prince made an offer to Cariou for those remaining images that was agreeable to both sides, insofar that it would have avoided the need for all parties to endure further time and expense in another round of court proceedings.
