As I’ve discovered recently SPP 5.5.3 is much faster than newer versions at processing Merrill X3Fs, but I find myself missing SPP6’s “color square”. IMO the older version has one additional advantage: its color rendition in regard to Merrill Foveon output is much better. When applying small color corrections, however, there is no way around the mildly speaking awkward “color sphere”. What I mean by that is that after all this time I still find it hard to remove a color cast with the sphere. Fortunately, as I’ve found out while processing my last batch of photos, which you can see below, SPP 6.2 is also able to eke out beautiful colors out of Merrill X3Fs. The most important thing is to manually tweak the settings, instead of trusting auto white balance.
You can see the proper settings in the screenshot below:
WB set to Daylight, color mode set to Standard and shifting color to the left, into the blue color range. When processing photos shot on a cloudy day, you should stay between 12 and 15 (for blue) and compensate with a bit of green and magenta, depending on taste and lighting conditions. The range between 20 and 25 (for blue) is a good starting point when processing photos taken on a sunny day. Here you should also compensate with a bit of magenta and green, if you deem it necessary.
