I'm gradually learning and adapting, plus have started using Raw Therapee to manipulate the .raf files from the Fuji. Raw Therapee has much more subtle tonal controls, plus a better de-speckle, while DigiKam is better at gross tonal changes and sharpening.
The Fuji sensor seems good at more subtle colours than the Samsung, though not without considerable help, but the Samsung is very much cleaner, even though it's an 8+ year old design. Noise doesn't show up at these sizes, but even at 100ASA it leaps off the page when pixel peeping.
But the good thing about the Fuji is that it makes me want to take pictures again, even with the hit & miss results it produces.
