Well, Alex, to tell you the truth about that cloth: it IS black!
I don't know why it came out this orange, or why the whole photo came out this orange. We had set the white balance to "tungsten" before this (which she had forgotten for her first attempts, like she had also forgotten to switch on the "flower" - so she'd be able to get close enough), and she has one short exposure with flash which shows the cloth in its normal colour.
These long exposures with flash at the start though, and then 6 seconds at f8, all came out this orange.
She did use her desk lamp, an orange "ball" (her newest light source), the ceiling lights ... well, yes, and those milliseconds of flash right at the beginning of the exposure.
(And she would not be able to tell you all this in English, meine kleine Deern

).
