I've just read that when shooting in RAW, the histogram displayed on the camera screen is based on the embedded or processed jpeg image rather than the RAW image.
Is this true? Has anyone any knowledge of this that they care to share?
Thanks

This all sounds about right to me. The fact is that when shooting in raw, with my camera at least, the image on the camera screen after a shot is taken always looks different to the one on the 'puter screen when its downloaded
Purely out of interest I thought I'd test this on my old "Bridge" camera. I set it up to produce RAW+Jpeg and the 2 files show very slightly different histograms. This is confirmed when I import them to the computer.
It would seem that my old camera is doing a better job than some of the new DSLRs.

How interesting, I shall being doing some comparisons myself to see how much of a difference there is.

I guess there isn't any hard and fast rule. What if you are not shooting in a mode that produces a processed image (in RAW-only mode)?
And there is of course a difference between a live histogram, in cameras that can do this, and one based on a taken image.

And it will look different in different RAW packages as they all have different preset configurations that produce the view in that package.

I almost always shoot RAW only, so when I was told about the histogram not being produced from the RAW data, but a jpeg "version", it started me thinking.
My trusty Olympus C-8080 has provided the answer, in its capability of producing RAW + Jpeg files from one shot, that are able to be viewed independently on the camera screen with the histogram displayed.
There are differences, and these are to be expected, the files are after all different. The important thing for me is that the Olympus firmware in the 8080 does such a good job of converting that the difference is so small that unless you really are looking at it super critically, the difference isn't worth bothering about.
