If I understand correctly (and startrekhistory can weigh in for themselves if they wish), startrekhistory, as part of their restoration process not only placed watermarks on the images, but was able to insert certain "tells" into the image. Their confidence is high that the genealogy of the Collector's images can be traced back through their restorations, and not through someone else's parallel restorations. I think if they reveal what those tells are, then the Collector will be able to figure out what to do in order to circumvent them in the future.
I'm sorry but I don't believe Startrekhistory about this supposed "tell" in the photos. I don't believe it's possible to say with any amount of certainty that the pictures in the book have been geleaned from their website. I think they have intentionally stirred up the pot out of jealousy, animosity or some other motive against Marc Cushman. I can't understand all that's behind them trying to take credit for what doesn't legally belong to them either. I have looked through many of the photos on their site and the restoration work is nothing more than poor Photoshop color correcting, which anyone, myself included, could do with the same images they own. I commend their desire to take photos that have long been available and make them more presentable on the web but that gives them no specific rights whatsoever. In fact what they have done is technically illegal because they do not own the pictures. As I have emphatically stated before, and will once again, the only owner of copyright on those photos are the "photographers" themselves. You may buy and purchase copies of photos but doing so gives you absolutely no right to reproduce, change, or modify those photos without the photographer's permission. It's obvious that many people here feel that Startrekhistory has some kind of rights when in fact they have none and in fact have violated the rights of the photographers. This copyright law about the ownership of photos has been around for many many years and is the reason why photo copy centers must have photographer copyright release forms. Especially if the photo appears to have been done by a professional or contains content that would infringe on the rights of persons within the photos. I dare say Startrekhistoy has probably never sought out any permissions whatsoever from the photographers, actors, or others displayed in the content of the photos.
So, perhaps Cushman was wrong in gleaning these photos, which has as yet NOT been proven, from Startrekhistory, but Startrekhistory is just as guilty of copyright infringement and their site should be removed immediately until they acquire the necessary documentation from the photographers and actors whose images they are illegally hosting.
