Here's new versions of my custom 645z profiles:

It's not that I'm into making profiles that much, it's doing the software itself (DCamProf) that is my thing, but I've had quite much interest in the 645z profiles as the Adobe bundled profile is not that good.
The new versions fixes some clipping (extreme colors) and gradient issues (sunsets) with the old. The "Neutral+" is looks almost identical to "Neutral" but have some subtle adjustments:
- longer rolloff to white in skin-tone range to improve look of high-key portraits
- shorter rolloff to white in cyan-blue-magenta to improve color of skies
- slight warmup of midtones and highs in greens and yellows for making sunlit
areas stand out more in landscapes
- slight saturation increase, skin-tones excluded as well as already highly saturated
colors
- slight reduction of green component in oranges to get better separation between
greens and reds (for landscapes)
If you've used the previous version they look about the same with one major difference: blues are rendered lighter. This is both for a subjective reason (lighter blues improves tonality as it moves blues into a zone where the eye is more sensitive) and a technical one - many Sony sensors have such a sensitive blue that it becomes very hard to render blues realistically dark without aggressive LUT bends towards the gamut edges. By rendering the blues a bit lighter than realistic this problem is avoided.
The profile is still rendered from a single CC24 shot from Imaging Resource (I'm a Hassy user myself, I don't have a 645z). It works well for D50 light.
