Section 2: Creating an HDR image and processing it with Tone
Mapping
There are two steps involved in creating and processing HDR images:
Step 1 merges your photos taken under different exposure settings into a single 32-
bit HDR image. Because of its high dynamic range, the 32-bit HDR image will not display
properly on conventional monitors.
Step 2 processes the 32-bit HDR image via the Tone Mapping tool. Tone Mapping
will ‘reveal’ the dynamic range captured in the HDR image and produce an image that
can be properly displayed on conventional monitors and is ready for printing.
2.1 Creating a 32-bit HDR image
The easiest way to load the bracketed photos you want to merge into an HDR image is by
dragging them to the open Photomatix Pro application (Windows) or to the Photomatix icon in
the Dock (Macintosh). Then, select the “Generate HDR image” option.
Alternatively, you can also click on the “Generate HDR Image” button of the Workflow Shortcuts,
or choose Process > Generate HDR.
If you have Lightroom, you should use the Lightroom Export Plug-in to Photomatix Pro for
your RAW files. Please refer to section 5 of this manual.
If you have not dragged and dropped your images, click on the “Browse” button of the
“Generate HDR – Selecting source images” dialog. An Open panel will be displayed to allow
you to select your photos taken under different exposure settings. Highlight the image files that
you want to merge into an HDR image. Then, click on the “Select” button, and click “OK” to
proceed further.
In case the exposure information cannot be found in the metadata of the image files, Photomatix
will show a dialog where you can input the relative Exposure Values for each one of your
images. This dialog will also be displayed if two or more source images share the same
exposure information.
The order of the files in a bracketing sequence does not matter. Photomatix Pro will
systematically sort the image files based on the exposure information retrieved from the
EXIF data. If the exposure information is not available in EXIF data, Photomatix will use
the relative brightness levels of the photos.
Photomatix Pro can generate an HDR image from 8-bit, 16-bit, and RAW source files.
Supported file types include JPEG, TIFF, PSD, DNG, and RAW files from many camera models.
As the list of supported camera models for RAW files often changes when a new sub-version of
Photomatix Pro is released, we suggest that you consult the Photomatix Pro FAQ on the
HDRsoft website at http://www.hdrsoft.com/support/raw.html
to check whether your camera
model is supported. If your camera model is relatively new, you may have to upgrade to a new
version, or wait until Photomatix Pro adds support for it.
