Affinity Photo uses LibRaw, so that's another option but...

Like my Custom sunlit card image, very pleasing colors!

That's a straight conversion, all defaults, no tweaking, which is very pleasing indeed! Far better than I can force out of SPP; and then you're stuck fumbling around in Photoshop attempting to achieve something vaguely aesthetically pleasing 

... I don't know if it's using the WB matrix in the X3F metadata − I don't have any FS shots sans Custom WB to test.

Edit: it does by default but can be overridden by selecting a classic Kelvin/Tint WB tool.

Oh. A bit global, but better than nothing, I guess.

A global White Balance correction is ok at the conversion stage... if I keep repeating that I'll start believing it I'm sure.

But I've come full circle, I think that I prefer that palette over my 099 (550nm), digital photography really is nothing without the software!

Agreed!

My phone shoots HDR DNG, even my drone shoots RAW! I miss the flexibility of Aperture/Lightroom, but for Infracolour... Affinity is scratching an itch:

The bonus with working on the RAW data (per se) is that you have so much control − this is a FS shot, same as above, but I simulated a 550nm orange filter. Which just doesn't work on a converted JPG/TIFF!

N.B. LibRaw does no highlight reconstruction of Foveon RAW so 'overexposure' is a big no no!

I've never been a fan of "highlight re-construction" anyway. If desired stuff (e.g. clouds) is too bright in a converted but un-adjusted image, it's a candidate for the trash, IMO.

I'd much rather blow highlights than suffer SPP's treatment of 'under' exposed Merrill shots − so I've learned to live with SPP's rather good Highlight Control tool. But I admire your sentiment.

We should remember the "S-curve" in DPR's dynamic range graphs - where the curve at the top means that highlights may not be "blown" but they certainly can have less contrast than desired.

The 'Standard' tone curve for the SD1M, not sure what to make of that really
