Goes to show, that digital cameras, like film we put into SLRs of old, vary in the faithfulness of color reproduction!
Going waaaaaaaaaaaay back to the 10D, the review by (burns brain trying to recall, it was Popular Photography) said it was the most accurate color rendition of any camera that had ever been tested, .. period.
This includes any film ever.
Up until the 10D, this had been a quest for Digital, it was something Pop Photography had always tested, and people thought they wanted.
The result, was many people on forums like this one pissing and moaning about "washed out " color, etc.
We had grown used to Velvia and such, and accurate real life color, does not a good photo make.
The next Model in the line was the 20D, complete with the introduction of "Picture Styles" and the quest for accuracy was over.
Don't anyone kid yourself, if your looking to make photographic art, then color accuracy is not what you want. Photography is (most often) about making life look better than real.
So those of you that poo poo picture styes or any other kind of "look" being applied to a digital images, grow up. It's what every brand/make of film always did, and what your camera, or post process does anyways.
