What I can't quite work out is how to best work with HDRI in P7. So far all my experiments have yielded very unpredictable results requiring a lot of fiddling with settings to achieve any half reasonable renders. 
I kind of thought they might be more straitforward - like attach to the colour channel, set to 1 and go. But so far they're far from this.
They always render far too exposed an image, or totally over-saturate colour etc.
I must be missing something.

Any tips would be much appreciated.
