These are some photos I took, before I left Seoul, of the hoardings around the construction site beside City Hall. As I have mentioned before, the Koreans build very high quality hoardings around the building sites and put a lot of effort into making them look attractive. The hoardings beside City Hall are particulary impressive.
From a distance it looks just like a normal picture.
As you approach you realise it might be some sort of mosaic
As you get closer you see it is made up of small photos.
Once you stand beside it you realise how cleverly it has been put together.
The artist has used thousands and thousands of different photos, some of them going back to the 1980's of all sorts of places, events and subjects. The photos do not appear to have been altered in any way, and yet they create the picture you see from a distance.
It's well worth taking a close up look if you've seen it from a distance. I haven't been able to find out anything about the artist or how they did it so if any knows or can find out I would be most interested.
Update: Thanks to Mark for the explanation. It's a Photographic Mosaic. Obvious really! There are at least ten programs available to download to create your own mosaic, and there are also online applications, here's one, so it's not as difficult as I first thought.
Update 2: Thanks to Mr Kim at the Delta Eagle's OC for letting me know it's from www.byplot.com. It's made up of 6 million images.
Update 3: Thanks to anonymous, the artist's name is Sylver Kang. He used Mazaika software. You may see some more information on his website http://www.mazaika.com/seoul2007.html
