I posted elsewhere that "this year we reached that critical mass of Energy, Experience, Enthusiasm... and obEron. There was definitely a spark that really pushed this year's event over the top in terms of most modest expectations." The energy of Photostock seems to be continuing well past the drive home and the inevitable laundry that follows.
I learned so much in the presentations and discussions. I also learned (the hard way, of course) why IR photography does not favour featureless skies.
