2.2 Tone Mapping

The generated HDR image cannot be represented properly on screen without further

processing. An unprocessed HDR image is somewhat similar to a film negative or the RAW file

of a digital camera. It needs further processing for display or printing. In Photomatix Pro, this

processing is called Tone Mapping.

There are two tone mapping methods for processing the HDR image: Details Enhancer and

Tone Compressor.

2.2.1 Tone Mapping with Details Enhancer

Photomatix Pro defaults to this option when the Tone Mapping window is opened. Details

Enhancer utilizes a local operator to ‘develop’ the HDR image. This means that it takes into

account the local brightness context -- a pixel of a given value in the HDR image will be mapped

differently depending on whether it is located in a bright or dark area of the image.

Click on the Tone Mapping button on either the HDR Viewer window, the Workflow Shortcuts

window or the Process>Tone Mapping menu to launch the Tone Mapping tool for the active

open HDR image. If you have used the Generate HDR process to create a new HDR source

image, it will be the active image. Otherwise, open a saved HDR image file via the File>Open

menu.

Use the slider controls to adjust the image. The preview on the right provides an approximation

of what the image will look like once Details Enhancer is applied to the entire HDR source

image. In the case of the Details Enhancer tone mapping method, the preview is not always an

accurate representation of the final tone mapped image.
