@Sherlock77 Expression of emotions fits into this thread as an essence,
so discussion on taking photographs could have a meaning here.
You speak of not using emotion on the pic of the boys on the bench, yet I see in your photos an expression of the human state of being with no words needed.
The photos show this to me.
I wonder if you are projecting emotion through the photos of the various scenes of people?
I enjoy photography as a hobby, certainly not any type of professional. Just me and a little digital camera,
but I am attracted to inanimate objects or nature/animals. Not human scenarios.
This at first thought might seem opposites regarding emotions in the photos, but, upon deeper perception
there may be emotional expression.
Humans, their expressions and life activities evoke a sense of their emotion. A lot of emotions that I don't comprehend, but can somehow feel from the photos.
Inanimate objects not directly expressing emotion has the personality or emotion of the photographer,(me)
reflected in them. Like a mirror reflecting my emotions through what I like to photograph.
Into my overthinking maybe, but, interesting.
