What's wrong with this picture?

Inverting a positive scan of a color negative will give you a cyan looking image since the inverse of orange is cyan.

Dude.
The begining of your sentence made some kind of sense, but when you state something totaly wrong to explain it, someone has to say it's wrong.
I'm sorry not everyone buys all the bs you say.
And i know you're trying to be helpful and everything but just to convince the OP to get a decent scan of his image, you don't need to mislead him into believing some bs you just made up.
cheers.

Looks like it was mis-processed. Both the initial scan and the inverted scan are devoid of much color. Even this subject should have some color range to it.
