But what it will do is shift the data into an area where the sensor is better capable of capturing differences.

The whole idea centers around the idea that the sensors are more sensitive on the right side of the histogram (lighter side) than on the left side (darker.) So if you can shift your picture over to the right, you'll be able better off. If you have to increase ISO to get there, then it is (usually) still a win.

At least, that is how I take it.

Now what I don't understand is why the sensors capture more detail in the lighter portion of the picture than the darker. As an attribute of the sensor, that is. Why design them that way?
