I recently asked an art professor how do you teach someone to put their feelings into their work. He talked about technique, methodology, and craft. Finally, after pressing the issue, he said, "I'm more process oriented." In other words, he had no answer.
Maybe feeling can't be taught. You either have it, or you don't. I'm not convinced that's true. Everyone has emotions. Finding them, holding them, and allowing them to flow through you and into your vision takes practice and courage. Allow them to flow like water. Be genuinely a part of the scene. Immerse yourself in the moment. Allow yourself fall in love, shed a tear, smile, feel the joy, or the pain. Just be part of life. Until you can transmit that emotion to your images, they will be just shallow records of shadows.
