I've been a portrait photographer for many years and used many SLRs and DSLRs. All my portraits come out fantastically when I use good lighting. I've now tried the 7D on colour portraits and for the first time in my career, the colours don't really look that nice. Faces either look pasty or golden. I can't use this on a professional shoot. Tried all the pic modes: standard, portrait, neutral, faithful, landscape. 18megapixels is great, but useless if the colours aren't great. Even the old 350D gives nicer portraits than this. What gives?
