5DIV DPraw and 1 extra stop in highlights!

-

iliah borg, founder of rawdigger, wrote article canon's 5div dual pixel raw file format , how contains 2 distinct data sets, 1 main sub frame made of both dual pixels summed together, , auxiliary data set made of 1 of dual pixels. discovered auxiliary set contained 1 stop of highlight headroom not present in main sub frame. significant because extends dynamic range of camera on 14 stops! here example images showing differences. there has been lots of talk on various other internet blogs.

 

it revolutionary if adobe incorporate find converters. perhaps use highlights auxiliary data set when recovering highlights?

 

comments welcome.
