Please post the image/s in question on this Forum.
I wonder whether the pictures by itself can determine which tools were used for processing.
As far as I can tell that would be »no« pretty much except in certain »simple« cases, especially if one does not have the unedited image for comparison.
But even then an exact determination is likely impossible in many cases as the possible number of combinations of features and settings is considerable (unless the History Log was written into the Metadata).
With experience one may venture to make educated guesses, though, I guess.
Please post the link in this thread, too.
And could you post one of your images that you want to edit to emulate the effect?
To me it seems there may be some creative (over-)sharpening involved.
