ok, so i just spent a *considerable* amount of time reading the entire ruling.
and after reading (admittedly, not all of) the responses in this thread, some people are jumping to conclusions here.
bottom line- there was prior knowledge of the photo. the infringing photo is a composite.
There are many other similar photos out there, that was also noted.
Basically, the defendent set out to recreate the photo , in a composite. That IS an infringement.
The judgement actually states, that if an independant photographer had been given a brief to go and shoot big ben, the houses of parliament, and capture a red bus in there, that that would not be an infringement.
On seeing the photos, at first i too thought "how on earth is that an infringement". Reading the facts of the case certainly change that view.
