Adobe - through a combination of laziness, obstinance and arrogance -
throws them away and forces you to recreate them, starting from its
arbitrary set of assumptions.
Is it Adobe's fault? I thought that sort of information (Vivid, the
old Color Modes, etc.) can only be reproduced accurately using the
camera vendor's proprietary software. I don't think it's just an
Adobe thing...I know Aperture doesn't take those settings into
account either. Are there any 3rd party raw convertors that read the
picture settings info and try to do their best to match them?
edit: I see you mention the 3rd party software don't. I think it's a
proprietary Nikon and Canon thing, not any 3rd party fault.
