Hoping someone who has some experience with OCIO, espeically at Sony, can 
clarify this for me. I have been taking a look at the Sony OCIO docs and it all 
seems pretty clear, I notice that in spi-vfx  they are equating 445 (lg10 
value)  with 0.18 (inf, inh value) which is great and I like. 

What I want to know is, are Sony pre-treating any of the the Film Log files 
(for example lg10) or using some specific scanning correction not common to the 
rest of us ? If I just take a nominal dpx log file for example, Marcie. Read 
that in as Raw Data, then apply an OCIO Log Convert. Then her 445 swatch is not 
returning a..... .18 more like .1493. Same if I use an OCIO to Colorspace

or have I missed something ?
