Leon Krige; amazing photo art

My very resourceful friend, CG, told me about an exhibition of photographer and architect, Leon Krige, he attended (in Johannesburg). The photos are striking an truly amazing. 

I could not find more info on the technique, but according to CG a number of smaller photos are combined in a mosaic like fashion to form the very high resolution final product, as I said; truly amazing.

Apparently one can only fully grasp the detail and work that goes into these pieces when seeing it in real life. I for one would love to.
