IMHO LR enhance wins hands down. I am really surprised by the lack of
resolution and sharpness in the last three when viewed large. There is a
noticeable difference in the last three in terms of quality even at
"regular" size.
Erwin would not be impressed :-) Just look at the difference in the
pattern of the subjects sweater in each, let alone anything else.
I can't help noticing that there is a crop or shift of the subject when
viewed against the background in the later ones.
I am surprised!
