Apologies for what is probably a very noobish enquiry, but what are the values associated with 18% and 90% scene reflectance? For instance, when viewing a dng in Resolve in linear space and 18% scene reflectance is 20 IRE on the waveform scope (and 90% is 100 IRE), which original 14 bit values are they derived from? If white level is 15000, how many stops above 90% reflectance is that?
Many thanks in advance to anyone who can help clarify this for me.
