I don't know how this picture was taken, but one thing I have tried (though not very successfully) is to use a polaroid filter in the opposite polarity. That is, usually a polaroid filter is used to reduce the reflection, but if you turn it 90º you got the opposite effect.
Anyway, it is an extremely good picture.
