err, I really hate it to sound so picky but actually you can't use a 
mirror ball photograph without processing - at least if the image is 
used as a reflection map - because it will look distorted.

The generation of a photographic 'probe' works usually like this: take a 
two photos of a chrome ball from opposite directions.
Remap both images from the 'mirror ball' projection (sorry this time I 
do not know the exact therm - but maybe there is none) to 
latitude/longitude projection and compose them. Then map from 
latitude/longitude to angular projection to get the so called probe.

It is just a nice side effect that this way the reflection of the 
'photographer' can be removed, the importand thing is: The 'mirror ball'
*projection* is different to the 'angular' *projection*. But I admit 
they can very easily be confused.
