I've always wondered about this. With all the photography I've done I feel like I see the world in different ways than people who haven't done it as a passion or job.
For example, when photographing people the hands say so much. Are they clenched and to yourself, stiff and hanging by your side, or are they relaxed, placed softly upon someone's shoulder you care about?
Anyway, WIRED did a whole thing on it with our friend Chris Burkard. Chris even used some of our SmugMug footage from the film we did of him photographing surfers in the Arctic.
One disturbing conclusion: some people want their noses narrowed with plastic surgery because the wide angle phone lense they use for selfies makes their noses look wider.
