I have been running RAW on my DF and both on the D 750 for the last six months, but it just isn't for me. Using JPEG fine / large I get a much higher percentage of images that didn't require any post processing to meet my expectation and the vision I was trying to capture. Partly, I suppose, since I tend to use spot metering the same as I did for film and "trick" the meter to get what I want. Since post processing is not something I'm particularly fond of, and nearly everything in RAW seems to require some, though it is heresy, I changed back. Between less satisfactory results, the large file size, slower speed to load, and my dislike of PP. I'm thinking my test was a waste of my time. In any case, as an amateur, my photos only have to satisfy me, and are not likely to "be for the ages." Though I'm sure most will disagree, some few might consider their own situation and agree..
