The unfortunate thing is that because its very dry and dusty where these pictures are being taken, the dust gets thrown up into the air, even from just people walking around. Thats why you have (a lot of) orbs. There is nothing wrong with your camera. The thing is, that because digital cameras
are so good, they do pick up virtually everything, which is why I reiterate my point that in 'old' ghost photos there were no orbs. The photographic technology was'nt as advanced obviously, but this is the reason why I don't believe in any way that orbs are proof of spirits. Orb mania came about with the digital era. Anybody, and I mean
anybody can snap random pictures with a digital camera in
any location, and get orbs, they're not ghosts, people!!!!!
