Hi Rob,
Thats what I am saying.
Do an experiment. Take a picture in camera as a jpeg then follow the tutorial above, the part where you open in raw from bridge. You will then see that there is no data or it won't open.
Then try it my way with the tutorial above and you will then see that you can open from bridge into camera raw and have full RAW data.
I have to do this technique a lot.
If you have ago let us know how you got on.
Happy christmas.
