Thank you for your quick reply. That is reassuring (I guess).
Now another, probably dumb, question: what does "supported" mean? I have a question about some photos taken by the D7500. If this camera is not yet "supported" would it be difficult, or even impossible, for someone to answer it? I will offer the question anyway, to see what happens.
I took a series of photos with the D7500, then loaded them into two different programs to look at the histograms. One program was Affinity and the other is a "View photos"-type program from Nikon (View-Xn-i). I am attaching snapshots of the histogram from each program. They are quite different, and I am wondering why. Which histogram would be the more accurate one?
I do not have Lightroom (heresy!) or any other program with which I could compare the histograms, so I am not sure what to make of the different results.
