Our Friend The Histogram

[another view]

The distance between the left and right terminus of the histogram is the dynamic range. (I'll post images later as I've just sat down in front of the computer). This can also be thought of as the dark to light or Contrast range. This is where the Expose to the Right as a rule falls down. If you have dark subject, like that displayed, to get the images histogram very far right toward the light or "white point terminus" or blown highlight, will over expose the photo.

There is NO inherently bad histogram. They reflect the what the camera sees.

I completely agree. My mid-tone shot of the trees could be a candidate for "Expose to the Right" but that's not always the case in real life. Often not the case.

Here's a more normal light situation, and a histogram that nearly goes from end to end. Exposing to the Right would have lost the highlights. Matter of fact, if you look close at the histogram there is a little bit of blown highlights in it already. It's probably the map in front of him (next to the water bottle) and some specular highlights off the water. Not a problem IMO.
