I'm interested to know how Andrew Lesnie achieved the "highlight blooming" effect throughout the Hobbit trilogy. Did he use a filter (pro mist?), net his lens or was the effect done in post? Either way, the footage is very lovely and it was shot on an old Red Epic camera with Zeiss Ultra Primes.
I had the privilege of talking to Andrew before he passed away at an ACS meeting in Sydney a few years ago, but I never got to ask him how he achieved this effect.
