I was testing light ratios and am perplexed as to why my grey canvas background appears brown. Shot 800 ISO f8 on subject, f4 metered the backdrop. Please help.

I digitally test the exposure before shooting my film.

You need to explain more what this is. Is this a film scan? color negative or chrome? What kind of lighting etc.

Shot with Nikon D70 (to preview before exposing my 120, 800 ISO Portra) and a Hensel Integra 500w strobe. The backdrop, from Franklin backdrops, is ash grey.

Was there any ambient light (light apart from the flash?)

I had a regular standing lamp on in the room but thought the high shutter speed would've killed the ambient. It was shot in the evening.

The background was probably receiving somewhat different light than the subject.

Unsolved mystery, all ambient light off, still brown?
