Why when I export my photos does it automatically apply a PhotoDirector Watermark - these are my photos, copyright belongs to me?
CyberLink PhotoDirector is not a free product. You can download a trial, but a trial although it works normally has limitations like watermarks applied to your images. It really doesn't matter if they're your images or not, since you're using a shareware product that requires activation. The full version of the software doesn't have watermark or any other kind of limitation.
The full version of the software will cost you around 60 Euros and it's available from its official website: http://www.cyberlink.com/products/photodirector-ultra/features_en_EU.html?&r=1
