I haven't found any white paper for D-log M color profile and how to expose it correctly.

First of all, is there any reference for IRE of 90% white or 18% middle gray for that profile? Or at least if we should shoot 0.0 EV or overexpose (for example +0.7 EV).

Secondly, what is the preferred base ISO for best dynamic range? I assume for normal Rec.709 profile it's ISO 50, however usually for Log profiles the base ISO is much higher. Any guidelines?

The spark doesnt support D-LogM
