Is the laptop what caused the wild over-sharpening?
Absolutely, Russ. But indirectly of course. I spend as little time as possible processing images on my laptop when travelling. The niceties of an appropriate degree of sharpening for a particular print size are not relevant. The purpose of my carrying a laptop when travelling is to be able to organize and store my images, and review them as I travel, searching for mistakes I may have made, such as an insufficiently fast shutter speed, inappropriate choice of aperture for the desired DoF, misfocusing or plain bungling which might, when I'm aware of it, motivate me to reshoot the scene if I'm still at the same location.
The purpose of showing the above shot, taken a few days ago, was merely to illustrate the major flaw of a wide-angle lens such as the Nikkor 14-24, which can produce some serious volume-anamorphic distortion near the edges and corners of the frame.
What I find surprising is that the 'lens profile corrections' in ACR actually make such volume anamorphosis
worse, in addition to cropping the frame in a way which might not be desired.
DXO have some dedicated software which can automatically correct such distortion, but with the disadvantage of cropping the image even more than the lens profile correction in ACR does.
The best way I've found in dealing with such distortions is to manually correct them using Free Transform and Warp in Photoshop.
The attached three crops show, from left to right, (1) the image
without lens profile correction, (2) the image
with lens profile correction, (3) the image after my manually selecting the area at the right edge of the frame and applying Free Transform and Warp.
Hope I've satisfactorily answered your question, Russ.
