Producing Realistic Images with High Dynamic Range (Part 1 - Part 2 - Part 3 - Part 4)

Step Eight:
Click the Post-processing tab to make Tone mapping adjustments. For this tutorial, the values used are -5 for Shadow, -10 for Midtone, and 10 for Highlight.

Step Nine:
Click OK to apply the adjustments to the image and close the High Dynamic Range dialog box. A new document will be created containing the optimized image. Select File: Save As to save.

The optimized image contains a greater tonal range.

Applying HDR to a Single Image
You may also correct the exposure of a single photo using High Dynamic Range. Even images with subjects in motion can be optimized provided that you use the camera curve profile for the digital camera used to take the shot.

Step One:
Open the image in PhotoImpact.

Step Two:
Select Format: High Dynamic Range.

Step Three:
For faster processing, select the Camera curve profile that you previously saved for your digital camera. Refer to the section on "Creating a Camera Curve Profile" regarding this.

Step Four:
Click Compose to create the HDR image. This takes you to the Optimization tab where an optimized image based from the tonal information from the HDR image is shown in the Preview Pane.

Step Five:
Click View HDR Image to view the full range of the HDR image’s darkest shadows and brightest highlights. The image in the Preview Pane is the HDR image. Due to your monitor’s display limitations, only certain highlight and shadow ranges can be shown at a time. Since you can only view a certain highlight and shadow range, move the slider to view a particular range. Move the slider to the right to view a particular highlight range value or move it towards the left to view a particular shadow range value.

Step Six:
Click View HDR Image again to return to the optimized image.
