help me, help me - lost a thread

[The_Traveler]

I saw a thread somewhere here in the last week.
It was a photo of a 11 or 12 year old boy taken out in the late day sun; his face was brightly lit on one side but the very front of his face was darkly shadowed.
The OP showed both the color and the BW conversion.

I've been trying for 20 minutes to find that thread and can't.
Can anyone point me to it?

TIA,

Lew
