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

[Sonny Carter]

My take after giving PS Enhance a try is that it is awkward to use and
gives you little control.  I don’t like that you need to be in raw to use
it.

I go to Gigapixel and Sharpen at the end of my work stream, then I can use
it at the strength I need it.

Enhance needs some enhancement.
