Finally, got arount to doing pp, but it wasn't easy - files didn't click with the software, very peculiar (because I have used darktable countless times to edit NEF files, and there never was any trouble). I suspect the camera's on its way out - why, I can't fathom, but it's the way of things, i.e. they break. Anyhow, here's yesterday's shot:
I was considering experimenting with Darktable, but one of the things I've kept alive and transitioned to every PC for a couple of years now is my still functioning copy of Capture NX2. I have way too many NEF files, including V1 shots, not to keep it going if possible. I fear for the day I can't make it run under the latest OS.
