There are different anomalies which may show up in your ghost picture. Some of the most common are as follows...

1) Orbs – round spheres of light that can be caused by flash reflection off of reflective surfaces, dust, glass, insects, moisture, etc. Of course, many believe that some orbs are "spirit…maybe even the souls of people. They have been captured in movement with a vapor trail; and have also been photographed with super-bright (often orange) energy – called "super-charged orbs."

2) Ectoplasm – smoke-like, fog that is not usually visible to the naked eye, but appears in the ghost picture. Many believe this to be "spirit" captured in picture. Of course, it is possible for cigarette smoke, fog or even breath from the photographer to sometimes reproduce this effect. So, one must be aware of this when taking ghost pictures.

3) Vortexes (vortices) – "funnel-shaped" energy usually encompassed or comprised of ectoplasm. Some believe this to perhaps be a portal or opening between the spiritual and physical worlds. Others believe these to be nothing more than the camera strap having been accidentally photographed.

4) Apparition – the Holy Grail of ghost pictures; capturing a full-bodied spirit in a "see-through" human form. These are rare, and some ghost hunters maintain they are not possible to capture, but just a Hollywood movie version of what a ghost looks like.
