In linear float, not just linear. The page
http://mysite.verizon.net/spitzak/conversion/multiply.html is like
"
1. Downconvert the frame to 8bit
. Apply a x5 brightness to light up the part that's in front of
the tree
. Shoot to video
2. Apply the x5 brightness on the half-float EXR image
. Downconvert the result to 8bit
. Shoot to video
"
He has also http://mysite.verizon.net/spitzak/conversion/blur.html
about night shots and lights. Composing the original image and the
blur with roll off one gives a nice bloom result.
What I will not disagree is that if you can have all the range with
lots of steps, better.
