Deghosting Options

Deghosting addresses the problem of artifacts that appear

when combining the bracketed images of a dynamic scene�

For example, if the moving subjects are people walking, the

people will appear multiple times in the combined image, once

for each frame, faded and in a dierent position as if they were

“ghosts”� This is why artifacts that arise from movement in a

scene are commonly referred to as “ghosting” and the

techniques to eliminate them are referred to as “deghosting”�

Show options to remove ghosts activates the Deghosting Options window, which will open after you

select your merge to HDR options and then click the Align & Show Deghosting button� The Deghosting

Options window provides an adjustable image-wide Automatic Deghosting algorithm and, for more control

over deghosting, a manually applied Selective Deghosting Tool�

Noise Reduction Options

The Reduce noise on option processes

source photos with a high-quality noise

reduction algorithm, and is recommended

when processing RAW les directly in

Photomatix� Noise reduction is typically most

helpful in dark areas of the source images,

and these dark areas are more prevalent in

the underexposed and, sometimes, in the

normally exposed frames�

With this in mind, you can use the Reduce noise on menu to specify that noise reduction be applied only to

the darkest images in the bracketed set� Or, if you wish, noise reduction can be applied to all images in the set�

Strength: Increases or decreases noise reduction strength relative to the automatically determined default

strength value, which is based on the noise level in the image� Values range from 50% to 150%�

Reduce Chromatic Aberrations

The Reduce Chromatic Aberrations option automatically corrects color fringing due to chromatic

aberrations of the lens� Checking this option is recommended, given that chromatic aberrations tend to show

around high contrast edges, and are particularly an issue for HDR images�

Noise reduction options

The deghosting option is effective when

you apply a Tone Mapping method (Details

Enhancer, Contrast Optimizer, Tone

Compressor) or the Fusion/Natural method.

It is not effective for the other Exposure Fusion

methods.
