Recently I stumbled upon a X3F Merrill raw image output thanks to RawTherapee converter. I heard Foveon files are noisy even at iso 100, but had no idea how much. Noise can be tamed quite well with either X3F_Tools or RawTherapee, but a lens color cast is something only SPP can rid of completely at the moment. Lomography fans may find Merrill processing in RT quite delightful.
Are there any profiles available for DP Merrills to remedy color casts?
I tried x3f_wrapper (https://github.com/Kalpanika/x3f_wrapper). It does a good job, noticeably better than a RawTherapee output, but still not a match to SPP in this regard.
I'm quite content with the SPP processing, just wish I could get those cropped 102x66 pixels back
Below is a comparison between SPP and RawTherapee conversion of a DP1M file at iso100 (DPreview test scene) to show how much color cast there is in uncooked X3F:
