support "linearized" (de-mosaiced) DNG as input. I don't think stitching
before demosaicing is necessary or even useful, but I'd LOVE to have a
demosaiced RAW stitcher, so I can then perform final corrections to the
equirectangular image in my RAW processor of choice.
As for vignette and CA correction, I don't think, IIRC, that these steps
are done until after demosaicing, so I see no problem in principle with
performing these steps on processed 16bit TIFFs either. The difference, if
any, between the two would be insignificant. If it was a concern, then
using a linear 16bit TIFF output from your RAW file, using dcraw for
instance, would be roughly equivalent anyhow. There's so much tonal
manipulation happening anyhow as a result of the blending, that I tend to
look at VC, in particular, as just a first step in eliminating seams. CA
is different, of course, and needs to be done before remapping, but maybe
not before demosaicing of the RAW data. Certainly, if we could stitch with
linear DNGs we'd need to integrate CA correction into the process.
