The way I look at it, its showing HDR capabilities. Because every picture below the Eiffel tower is overblown, either too dark or over exposed. Only HDR can help here, so its another tease about Lumia 920' camers, IMO. Ican't wait to get my hands on this manly beast:D
High Dynamic Range. Essentially the same picture gets taken multiple times with different exposures and then recomposed as a single image with incredible quality. Some people don't like it because it may look "too good", but it can be fun.
