How can convert a photo in LR to get only the edges of all objects?
I've asked this question about 2.5 years ago here, and Bruce and Jostein
have offered a couple of ways to do that in PS.
I 've been trying to achieve this effect in LR by playing with the tone
curve, but I cannot so far.
In essence, I am trying to get this type of image where only edges are
visible:
http://42graphy.komkon.org/swing/ch-2008/1-selected/IMGP4530_1.html
I've got close to that by essentially bringing the entire curve down, with
only a spike in the mid-range. That highlights some edges, but
(1) not all of them and (2) it highlights some non-edge areas.
I am starting to think it might not be possible in LR...
Any ideas?
