2.2 Processing the HDR image with Tone Mapping

Tone Mapping is necessary to reveal the details in shadows and highlights in your 32-bit HDR

image created from multiple exposures. You can either use Tone Mapping immediately after

having generated an HDR image or after opening an existing HDR image file that was

previously saved. To access the Tone Mapping tool, click on the “Tone Mapping” button on

either the HDR Viewer window or the Workflow Shortcuts window, or choose Process >Tone

Mapping.

Photomatix Pro offers two tone mapping methods:

 The Details Enhancer method is based on a local operator, which means that it takes

into account the local brightness context for tone mapping. Pixels are processed differently

depending on whether they are located in a bright or dark area of the image. This method

offers settings that let you process the image in creative ways.



The Tone Compressor method is based on a global operator, which means that pixels

are processed independently of their surroundings. This method produces more ‘natural-

looking’ results.

When you start the Tone Mapping tool, you will get two windows:

1) The “Tone Mapping Settings” dialog provides sliders to adjust the tone mapped image to

your liking. The dialog also lets you save presets or load existing ones. The tabs on top of

the dialog let you switch between the two tone mapping methods. The “Process” button at

the bottom of the dialog will process the entire HDR image so that you can then save it.

2) The “Tone Mapping Preview” window provides a preview of what the image will look like

once the Tone Mapping has been applied to the entire HDR source image and includes

options to adjust the size of the preview. Note that, in the case of the Details Enhancer

method, the preview is not always an accurate representation of the final tone mapped

image.
