[Leica] Print enlargement

[Ken Carney]

This may be old news, but I thought it was interesting.  Here is a photo 
where I couldn't get close enough with a 200mm lens, and had to settle 
for a crop of 1677x2516 out of 3744x5616, or a 6x9" image at 279ppi.  I 
got a trial of Topaz AI Gigapixel and enlarged it to 22x33" at 300ppi.  
This was out of curiosity since I don't have anything that will print 
that large.  But, it looks promising for small crops to print, say this 
one at 12x18", about the largest I print.  Topaz's pitch is that this is 
not interpolation, but an artificial intelligence program ("deep 
learning" they say) that in effect recreates the image.  Whatever, it 
seems way superior to Photoshop interpolation or Alien Skin Blowup.
