HI Vth_F_Smith
I HAd Revise Ur posteffect.Xml...
U R Disable the sepia_opacity to 0
But it Was too Dark....Coz the some light is disble...
Moreover,A lot of Reflection r disapper...
So ..I think that May Be use the sepia colour in White....
It will Better....And It's Work
This is sepia_opacity to 0...
This is
<sepia_r x="1.000" y="0" z="0"/>
<sepia_g x="0" y="1.000" z="0"/>
<sepia_b x="0" y="0" z="1.000"/>
No change for the sepia_opacity
