Also  thinking about this, some Camera do have modes that can be set or custom modes created to give better colour reproduction, and I have also made my own actions in Photoshop CS4 to automate the process, which can be handy to save time.. Saving files in Tiff from the raw files prior to working on them will also retain more information.
