For The Top photo:
a) This photo was taken for the purpose of capturing a cool moment and cataloging my progress in skating
b) The emotional relationship is pretty neutral, it was just a friend of mine filming
c) I suppose its viewing context of this photo would just be showing off, meant to be viewed by anyone who cares, but i suppose more aimed at people who find skateboarding interesting. It's not a photo that is meant to be taken too seriously or studied for a long amount of time.
For the Middle photo
a) I was taken to capture a moment of beauty.
b) The emotional context is one of love, the woman in the photo is my girlfriend.
c) It is more of a personal photograph and I took it for myself really, but it could be for family and friends as well. It is meant to be viewed for an admiring moment.
For The Bottom photo
a) It looks like it was taken to capture a moment of pain and loss.
b) I would guess non-personal, as I don't think someone close to the person would pause to take such a photo and seek to comfort her instead. Unless that person is an "artist".
c) I think it is meant to be viewed by anyone really; pain in universal. As a very emotional photograph, its intended viewing time could be longer. It takes time to soak up the agony of the photo, as it summons memories of despair in the viewer.
