[Martin Vignali]

I don't have a strong opinion about duo tone (i never use it)

I think it's better to have the real color :-)
But i don't know how to interpret the DuoTone information

"Other applications that read Photoshop files can treat a duotone image as
a gray image, and just preserve the contents of the duotone information
when reading and writing the file."

So probably ok in that case, but maybe with a warning, so the user can
know, that the file is not correctly decode.
