Just got my new X100S and am 90% enthused and 10% dismayed. It's clear that the blacks are clipping badly when shooting in JPEG, plus the compressing/detail/artifacting is not good and there is noted posterization in the shadows. The RAW look great, but the JPEGs are miles behind the X-Pro1 in terms of quality. Working on finding a solution... maybe Shadow tone -2 and then apply a batch curve to all the JPEGs? It seems to help. But basically there's no detail in the blacks especially if you try and pull them up at all even one stop. See attached comparison images. I was expecting the X100S JPEGs to equal the X-Pro1 JPEGs, but they're miles off unfortunately. Now if only there was a good tool to quickly process .RAF files with good results. Some day maybe.
Attached are some images all shot in Standard:
1) An ISO 800 JPEG pushed 1.5 stops side by side with the same image RAW file in Accuraw. The JPEG is lacking significant detail and has some gnarly color posterization that really shouldn't be there when shooting in Fine JPEG.
2) An ISO200 X-Pro1 JPEG next to an X100S JPEG, same aperture, ISO, shutter speed, both pushed 1.5 stops to see what detail is available in the shadows (none on the X100S JPEG...)
3) An ISO200 JPEG OOC, 1/60, f4 showing the painfully clipped blacks.
Anyone found a remedy to the mediocre JPEGs on the X100S? I'm going to try Shadow Tone -1 and -2 to see how they do and if that'll open up the shadows.
