you wasn't supposed to look at them in the DARK!! You coulda been scared!
A few of them DID scare me! But most of them can be easily explained Jess.
The "zipper" picture is clearly a camera cord. I don't know if this was done intentionally or on accident. Often times those "vortex" ghost pictures are actually camera cords getting in the way of the camera lens.
The "orb" pictures are most likely caused by dust. This happens frequently with digital cameras. Sometimes a bug flying in front of the camera will cause an orb effect too. Often times, people will be fooled into thinking they actually captured a ghost on film when they see this anomaly in their pictures. But it's almost always due to dust or bugs. If they had taken these pictures with a film camera, I might be a little more impressed, but I feel pretty certain most or all of those photographs were taken with digital cameras.
The "exploding" car, as well as the sparks reflecting off people's eyeglasses can be achieved by opposing the camera's aperture with an acceptable shutter speed (bulb,or indefinite amount of time the shutter remains open). You've probably seen pictures taken at night where the lights from cars travelling down the street look like streaks of light. Same thing here.
The "tube" and "saucer" pictures look a bit tricky too. If you look closely, it appears as if those images were cut and pasted from another picture, the sharp edges of the inserted image then blurred or smoothed in order to make it appear as if it belongs in the photo. I'm not certain, but it sure does look like a badly done "cut and paste" job to me.
The "disappearing color" from some of the photos was probably caused by the camera's infrared, or night vision system. Many cameras these days have such a system; even many film SLR cameras. If the infrared is used without a flash, the resulting image will appear as muddy gray, or sometimes green. So no big deal there either.
I'm hoping the photographer is inexperienced and is not trying to dupe the Internet community. But who knows?
A few of those pictures are very spooky though, because I have no explanation, and I got cold chills when I looked at them.
