I agree. Something I'm becoming more and more aware of and sensitive to. The interaction between photographer and model and what they create together. The experience of the shoot, not just the having of the final image to show for it. These things I value.
Definitely - once emotions come into the photo, they come through. Like music. Gremlin believed that you had to be 100% committed to the performance you were giving while recording a song, because exactly what you put into it at the moment of recording would come through to the listener on the conscious and/or unconscious level. Same idea I think.
It's just stuff I never thought about or felt for a long time, and really do more and more now. Being around people who also relate to these ideas and don't find it "silly" to talk about it really helps.
