Yes it catches a silly nanosecond
My mind took a different meaning. From my limited time in the photography world (and seeing it on TV) some photography people strongly believe an unplanned photo captures reality.
While a planned photo only shows what people want to show... as in, I might be smiling in a planned photo, even if I'm not happy... which an unplanned photo might show.
I'm not sure what was meant... some people do dislike selfies.
Selfies are silly nanoseconds...
A picture is a picture where it is a plate of food, a cat sleeping, or of oneself each on captures some sort of moment in time
