I've found this an interesting thread, and applaud Lindsay for bringing it forum. It is the kind of thread that informs others, Pro and Amateur alike. Throughout this thread no names have been mentioned, wisely by Lindsay, and I think it has been good that no one has asked with regards to a hopefully successful conclusion.
Magazines may think that some contributors may take problems like this because the Photo magazine industry is a small world, and it may harm future offers of work, but what about the magazine getting a bad reputations for ripping people off? Mistakes can happen, and it is how the mistake is acknowledged (if at all) and if and how the person wronged is satisfactory compensation, whether that be financially or with work in the future.
As for not bringing something like this to a forum, it sounds like Lindsay has found it a positive action so far. For many, Photography whether it is a business or a hobby, is a solitary endeavour, being able to share with others who share same interest (for want of a better word), may be a good sounding board at a possibly stressful and upsetting time. And frankly is why a lot of us are here in the first place. You may also get advice on paths to take to resolve the situation to a satisfactory conclusion, as well as a shoulder to cry on or a place to vent. Keeping quiet about such things helps nobody but the copyright infringer.
It looks like the magazine has admitted their error, and it is now up to the magazine and Lindsay to negotiate a conclusion that both parties are happy with, but most importantly Lindsay is happy with. Fingers crossed it is done quickly and amicably.
I have only had one image (so far as I know) used without my consent (taken from a thread I posted here coincidently) and it is not a nice feeling when it happens. That obviously different to Lindsay's situation. However, if you are an amateur like me though, threads like this and others, and threads you may start yourself about misuse of copyright are very useful and helpful. Hopefully we will see them less and less, because it happens less, not because people are keeping quiet about it, but infringements need to be highlighted, and for serial infringer's, as a last resort, named so as people can make an informed choice whether to commence business with them. In this case we may not know who the magazine or camera manufacturer are, and as long as Lindsay is happy with the end result, that's fine.
