... can you take an excellent photo that is devoid of feeling? Are we as humans capable of such null feelings?
I would say without hesitation, No, and No.
Even 'null' human feeling is feeling: a good photograph of an old, rusted tiller in an overgrown field
forces the viewer, any viewer, to emote, to null it, so-so it or love it.
Then there is this much-more-extreme 1943 photo, which forces the gamut of emotion, reaction, feeling. It's easy to 'feel' the resignation of the doomed prisoner, sense the mix of dread and lust in the crowd, but what of the heartless man raising the sword? Do we write him off as null? Was he deviod of feeling? No, sadly, he was just a human being with different feelings.
The range of emotion in this picture makes me wonder – going back to the OP – maybe you
can't photograph emotion. maybe
all emotion rests strictly within the head of the picture taker and each individual beholder and not a drop in the physical image??? Am I making any sense?
