If I understand this right now: It saves out to:
expose: 1
fstop: 1
asa: 64
gamma: 1
no matter what is your exposure or asa or fstop.
the vinietting is still applied though.
in 1.25 I belive it was saved to gamma: 1, but the other values where the same?
One thing I noticed though is,(if I´m not wrong) that the tone mapped output is comming out as float and not clamped
