I like to think that if I’d seen AKB48’s newest member Aimi Eguchi (江口 愛実) when she debuted, that I’d immediately have been able to tell that she was actually computer-generated. But I’m not so sure: whereas it’s pretty obvious in most of the shots here and here, I would never have noticed anything unusual about that ad above (all the members look quite fake!), nor that this and this picture weren’t of a real person.
It’s a little more obvious in the commercial itself though:
Thanks very much to @Septemberlena for letting me know about her. Unlike Hatsune Miku (初音ミク) that I wrote about two weeks ago, who very much resembles an anime character despite the impressive technology behind her, unfortunately such photorealistic idols clearly have a huge potential to insidiously affect teens’ body images. Especially when coming from a group as popular as ABK48.
