Do you believe in Auras?

I recently went to a Metaphysical fair and I got a photo of my Aura taken. Well, when the guy took the photo of my Aura, he pulled out the slip too quick and messed up my picture, but he went ahead and showed me anyway....It was really green with a small yellow center to it. The guy took another photo and this time my photo was almost completely yellow, except for a small patch of orange on the bottom right. No green at all this time.... I'm not skeptical about Auras at all, I truly believe that our energy "fields" (or whatever you want to call them) surrounds us......however, I'm not really sure this machine or Aura device was very accurate in giving photos. Later on, I had a Tarot reader give me a Tarot reading and an Aura reading as well. He held my hands really tightly and told me that the core of my Aura was a bright fuchsia color with bits of orange surrounding it, along with a muted green (which he said I need to work on), as well as some light and deep blues, however no cobalt blues and he didn't see very much red or yellow. I'm aware that our outside Aura will change ever few minutes.....they might change with our moods or with our thoughts, but you still have one color that is considered to be your "core" or "signature" color. I just wasn't really all that impressed with the photo I got because I don't really think it suited me. The Aura reading I got from the Tarot reading was more accurate, at least I thought so. Also I think I was really nervous so this probably affected the energy I was giving off, which probably made it hard to read my Aura. I don't know....Has anyone else had an Aura reading or had an Aura photo done before? If so, did you think it was accurate?
