The camera's maximum limit in terms of Dynamic Range is 2000% Scene Reflectance. What would the code value of 18% scene reflectance gray be in a 16bit Linear Raw File? Thanks

18% has no special meaning for raw.

Especially with the introduction of the SOS-based ISO definition ... which itself has become less useful with the increasing popularity of REI.

In other words, 18% is now whatever Chuck Norris or the Manufacturer says it is.

And back in the day when mid-gray was invented, Kodak said it was 16% anyway!

do not let the reader guess or google what the abbreviations may mean . Tell what it is about. Common and useful abbreviations can be taught too. I guess a term like saturation based ISO definition

SOS sure not ...---... distress

REI sure not Recreation Equipment Inc
