Now that we have a .EXR file laying around, it’s time to do some tone mapping. In this part of the series we’ll be looking at a script to tone map that file. Well, actually several scripts. When I prepare a photo from HDR I tend to use several different tone-mapping operators, and then I use the Gimp to combine them into a final image. Here we have scripts for the fattal02, mantiuk06, and reinhard05 operators of the pfstmo project. Then we have a wrapper script to make it easy to run all three tone mapping scripts with one command.

The next step in the procedure is to generate an HDR format image for each set of 5 images that we organized in Part 1. This part of the series is really very simple. There’s just one simple script to run in each directory that was created in the first part. Don’t worry, at the end of the series we’ll be wrapping it all up with a script to handle stepping through each directory.

Anyway, over the last year or so the script that I presented in Part 1 has changed a bit, so I thought I should post an update.
