There's a great post here by Ari Partinen with tips on taking better portrait photos with the N8, specifically looking at how he achieved the professional shot reproduced below, with nothing more than the Nokia N8 and some white material (as a reflector). Well worth a read and, if nothing else, shows what Xenon-lit fill-in flash can do to improve smartphone photos - even in broad daylight.

Below is the photo in question - link to larger 3 megapixel version - (I couldn't find a link to the 12 megapixel original)
