Yes it is. Unfortunately it is night right now, and Im too tired to power up my HMI Lights
So I will have to wait until tomorrow, to check the results!
I did some quick tests. Is this the way d-log is implemented on the Inspire and X-5? It's very odd. It desaturates everything, but it pushes RGB up rather than desaturating the colors down to protect highlights. I just can't figure out how d-log is useful.
