Another Photo Copyright question... Who owns the crops from the Chinese Gigapixel Panoramic?

Last month, photographer Jeffrey Martin presented one of the largest photographs ever created. 150 Gigapixel Image of Tokyo.

You can zoom in extremely close. The image is twice the size of Photoshop maximum. 20,000 times more detailed than an iPhone. 8,000 images were stitched together.

So, now Wired Magazine has an art presentation of crops made from the Martin Gigapixel image. Pretty cool images actually.

But my question is, Who owns the copyrights?

This is challenging previous notions of what it means to capture a photograph.

Other photographers are having curated art shows based upon Google Earth images and/or Google Street View. Who is the owner of this artwork?

See 9-Eyes surreal images from Google Street View.

Check out the gorgeous artwork of Mishka Henner compiled from Google Earth images.
