Change to copyright laws?

Hi.

I was recently viewing a web site hosting some shots taken with the FujiFilm XPro1. At the bottom of the page I noticed the copyright info., including the following: Use of any image on this website as a basis for another photography concept or illustration is a violation of copyright. This seems an unusual, and frankly, unenforceable concept, given the photographic content displayed by the photographers were generic (but nice) landscape and harbour side shots.

As someone who has studied fine art and graphic design, it is not uncommon to look to the work of others as a source of inspiration. It is, in fact, a time honored tradition. We as photographers/artists cannot help but be inspired by the work of those we respect and admire. How does one copyright the "headshot" or "three quarter with Rembrandt lighting" or "lighthouse in heavy seas"?

Not trying to be flippant but simply wondering if there has been some change to copyright laws in recent times.

Cheers.

Peter.
