Since you keep pushing Custom WB, Tom, what do you get over shooting with any preset WB and adjusting in post?

I'm not pushing it, I'm simply intrigued that you use and prefer RawDigger − if it's superior, then I'm interested!! And some things are impossible to recover e.g. "insane magenta," even working on a 16-bit ProPhoto TIFF, so a good starting point is necessary i.e. Custom WB.

While you were typing, so was I:

Bearing in mind that the SPP "magenta" comes from the green RGB channel being forced to zero, does a Custom WB actually fix that?

Apparently not, according to the above link.

I predominantly shoot with a B+W 099 infracolour filter, but see below for an FS shot (no critique needed, it was taken to confirm a good Custom WB, nothing else): Left is a default settings SPP export / Middle is RawDigger with 'No profile (raw colour)' / Right is RawDigger with 'Camera profile Embedded in RAW' ...

The 'Camera profile Embedded in RAW' version doesn't appear to have been White Balanced i.e. gain applied to the RAW channels to establish the correct White Point. Otherwise it's a very nice starting point!

The issue that I have with SPP is that there isn't a FS preset, so the colour mode and tone curve are not as I'd like and unadjustable. The right-hand RawDigger export is making me think that it'll be worthwhile to revisit UFRaw − with all of the additional RAW converter tools at our disposal... I'm excited

P.S. for Infracolour / NIR especially, working on an SPP 16-bit TIFF is an uphill struggle; bring on a 100% RAW workflow! Thanks Ted.

You're most welcome, Tom. I would be interested in any further work with RawDigger, of course.
