I know RAW means what ever comes of the sensor.
Okay, in RAW mode you can shoot in B/W mode. It shows sepia pictures in the viewing screen. You load it onto the computer and Windows RAW viewer shows Sepia thumbs. You load it into photoshop and it is colour again, not Sepia.
So, who is right? Photoshop or Canon and Windows? |

I think that you nailed it with your first sentence. RAW is whatever comes off the sensor. If you set the camera to sepia, it only treats the preview that you see, not the RAW file itself. The information is attached to the file to show any RAW development software what the basic settings are (e.g. white balance). These are normally applied in the RAW converter as a starting point. I guess that Photoshop didn't recognise the bit of data that indicates that the shot was intended to be sepia.

| Have you tried Canon's RAW converter? Maybe it will honor the "sepia bit". |

The reason why the Windows RAW viewer is showing sepia is that it doesn't actually read the RAW file at all -- it just reads the half-resolution embedded jpg inside of it. The in-camera processing is only ever applied to the jpg output, either as a full file jpg, or as the embedded preview in a RAW file. Importing the RAW file into an application that is actually reading the RAW data will result in a color image because there *is* no "sepia bit". The sepia toning is the result of multi-stage in-camera post-processing, and whatever is done would have to be re-done to the RAW image on the computer.
On the plus side, it's not hard to just desaturate and color shift in Photoshop, even if you don't have a plugin that will handle sepia toning automatically for you. |

so if you shoot RAW and choose sepia or b&w will you get a color RAW file plus a sepia or b&w JPEG file?

Correct. Best of both worlds, really. If you're shooting BW out of the cam you're giving up some range and soem options. With a full-color RAW file you have a fallback position for photoshop conversion. If the JPG does the job, you're good to go without that extra step.

Or some serious trashing-of-extra-files in the field, which is my solution.
