[Leica] Up-resolution with PS Enhance and with Gigapixel

[Aram Langhans]

Howard.  When I look at these I have to admit to myself that the Q2 w/o 
any enhancement looks best to my eye.  The PS Enhance does not look too 
bad, but the Gigapixle seems way overdone.  Edge artifacts make it look 
pushed too much.  Especially between the sky and rocks and the details 
along the light/dark edges on the rocks.  Maybe you pushed the sliders a 
bit too much? I would try a more modest attack with Gigapixle.

Just my 2 cents worth, but i see it is not in agreement with the other 
comments I have read as far out as the digest goes.

The two themes fit together nicely because up-res’ing could be a key to making the single-FL, high-Mpx Q2 even more versatile, by increasing the effective FL that can be realized from cropping and enlarging. I speculated that state-of-the-art up-res’ing by a factor of 2 might allow for decent prints (or viewing on a monitor) in the 25”-wide range of down to 25% crops (equivalent to FL 112mm). This is well past the Q’s ‘digital zoom’ limit of 75mm, which of course isn’t anything but a built-in crop since it (properly) doesn’t involve any image manipulation.
