Bouncing Light Off Dark Recessed Ceiling Problems

[JewelsOK]

I hope I am posting this correctly. I was shooting a 360 panorama with a Nikon D3000 and SB600 Speedlight in portrait mode with flash aimed straight up at the ceiling. Normally this works very well, but in this case the room had a deep recessed tray ceiling with and angled edge and painted dark red (see first photo) the effect it caused makes the walls look like they are two toned when they are not (second photo).

When I just shot my stills of the room I did not have this problem, but I'm guessing because I was standing along the edges of the room and the flash bounced mostly off the non-recessed portion of the ceiling.

What should I have done differently?

Naturally, bouncing off a colored surface will introduce a color cast. The recessed tray obviously compounds that problem. I think I'd try bouncing off of a side wall or behind off of a back wall. If that's not possible, then I'd try bouncing off of a white reflector held behind and slightly above you.

So there have been a number of posts that have had similar issues (inability to bounce because of too high ceiling, no ceiling or in this case a colored ceiling. Best bet? Bring a ceiling with you

Either hold a piece of white foamboard over the flash so that you have a white reflector or take the flash off camera and stick it on a stand with an umbrella/brolly/softbox/whatever.
