raw - Does Lightroom accurately show highlight and shadow clipping?

Lightroom has three places in the UI where it shows information about highlight and shadow clipping:

1. The histogram in the Loupe mode.


2. The histogram in the Develop mode.


3. On the image itself, by using red for clipped highlights and blue for clipped shadows, as in the following example:

Do all three accurately show whether there's highlight or shadow clipping in the RAW file? (I shoot RAW.)

I thought so, but I was told here that that's not the case.

This on the Sony NEX-5R and LR 5, in case that matters.

Answer

It does not show clipping in the raw file, it shows clipping on what you have generated from it. You will see that if you decrease the exposure or the highlights slider, the red area will change its size.

One way to see clipping in raw files (and dozens of other things) is to get a copy of RawDigger. Highly recommended, btw.
