That's where the anti-ghosting capabilities of your stitching software come in. Clouds are easy, being quite shapeless. People and other moving objects are harder, as doppelgangers of some idiot in a red coat can be distracting :mad:
Waves on a beach can also be problematic to line up ...

Sharpen seems to be pretty good at deciding what needs sharpening, even without masking. Hawthorn by kh1234567890, on Flickr

The auto setting process seems far too quick for Sharpen to be doing any too complex analysis of the image.
I agree that the optimum amount of sharpening depends on how the image is going to be viewed. In that respect Sharpen is a pixel-peeper's dream as it makes up texture detail right down to a crazy pixel level. I tend to use it cautiously and what I liked about it was that it did not give unwanted sharpening halos. Topaz have managed to break this in the current version and with my graphics card. :mad:

If I were them, I would choose images which make their NoNoise look good. That owl one is a very sad example ...

That is fine as long as you also allow for temperature of the camera and lens. And for ambient air pressure and composition as this will affect its refractive index. I'd also read somewhere on t'Internet that a freshly sacrificed black goat makes an ideal AF fine tune target ...

In the realms of consensus reality laws of physics do not apply. What you get is what the AI net calculates that ought to be there if you had more pixels.
At least Adobe limits you to 2x. With Topaz there is no such limit and things can get pretty wierd ... Topaz Gigapixel AI by kh1234567890, on Flickr

You can't move the focus point into the corners. :(
It is possible to get a reasonable overall focus by using liveview and slightly defocusing the centre - there is usually plenty of 'spare' sharpness there - to get the corners better. Or rely on your landscape shots having a nearer foreground at the bottom and a forgiving sky at the top.
Or fix it in post ... ;) Ash by kh1234567890, on Flickr

There must be something wrong with my DA12-24 @ 12mm ;)
The main purpose of the DA15 is to annoy you.
