Indeed, Denis, you understand what I mean.
I do shoot with RAW+JPG and at the moment, I sort my pictures by browsing, tagging, rating, flagging the JPGs, it's just more burden because when you apply 
filters afterwards to find only your selected images, well you see your JPGs, not the associated RAWs ...
I never use the JPGs to edit the pictures, I work on the RAW files of course.

I don't want the RAW preview to try to emulate the processing that my camera makes to create JPGs ! I know all too well, it's virtually impossible ... I've 
messed with dcraw and UFRaw etc for years ...

I would like the RAW preview to show me the JPG which is EMBEDDED inside the RAW file ! (which seems to be what we see in the thumbnails).

Image Preview (F3) doesn't show the embedded preview !

Look at the attached images for an extreme case (the photo is crap, but it's just to illustrate what I mean ... you'll see that the JPG shows really what I shot 
whereas the RAW preview (F3) I guess tries to automatically adjust the exposure and shows me something that I would want to put directly in the garbage ...


I hope it's clearer now :)

And no worries, I know the RAW workflow and how it must be done ;) It's just that when the RAW preview shows you a horrible image, it doesn't help the selection 
process :D

Have a good weekend,

Vince.
