Discussion on awesome lighting ???

OK, folks, a while back, there was a discussion on technique (as
usual) and one of the things that came up was from one person who
talked about "awesome lighting" --- 1/2 hour either side of sunrise
and sunset. For the life of me, I can't find it in my links, google or
saved posts. My grey hair is starting to affect me ... anybody
remember the discussion or have the links ? There was also
a web page the person had discussing the lighting. Thanks !!
