First, top row is my 6D in file browser, second row is from the editor. You can see that the file on the left has had the default profile/adjustments made. It has lowered the exposure but the file looks great.
Next, is the same set up with a Sony A7III file. Top row shows good color but once the raw is processed it is garbage.
Both examples above are with the neutral processing profile. I tried others (pop, natural, etc) with expected changes in the 6D and similar bad results with the Sony.
I first attempted this a month or so ago and was able to get almost acceptable results by changing black point, white point and all kinds of other settings, but could never get it quite there.
I did read a lot about RT and had some ideas about how I could get going with it but that was a month ago and I won’t embarrass myself guessing what is going on.
so what’s going on here?
