The Preview Window provides a preview of the tone mapped or

fused image as you adjust the settings, as well as the following

controls.

Previewing image adjustments

• Size Ratio: The radio buttons at the top of the Preview dialog may be used to select the preview size

related to the size of the original. For instance, 1/4 displays the preview one quarter the size of the

original image.

• Zoom: The Zoom slider scales the selected size ratio by a percentage.

• Preview: The Preview checkbox quickly toggles between a preview of the tone mapped image (the

default) and the original image. Use this to compare the eects of the changes with the original.

• Selection Mode: Checking the selection mode checkbox enables you to select an area of the

preview and replace it with one of the source images. See section 3.7 for details.

• Floating Histogram: The tone mapping Histogram is a oating window that contains four selectable

tabs to improve analysis of the image: Luminance, Red, Green, and Blue. In addition, move the mouse

back and forth across the histogram to display Level, Count, and Percentile information. If the histogram

is turned o, enable it by selecting 8-bit Histograms from the View menu.

Note

For the Details Enhancer method of

Tone Mapping and the Adjust method of

Exposure Fusion, the preview is not always

an accurate representation of the nal

tone mapped image.
