Tone Mapping

What is tone mapping?

Tone mapping has to deal with the image contrast.
You can make a single exposure look like a HDR image.   There are many ways to use tone mapping, I use it to bring out detail in the image.

As you see from my example below, the before image is flat, dull looking.  I then used Nik Efex Pro tone mapping filter and increased the contrast, thus increasing the detail.  It is more fun to play with than it is to explain.
