Auto Tone: Provides a good starting point for an evenly-toned merged image
Auto Align: Useful if the images being merged have slight movement from shot to shot. Enable this option if the images were shot using a handheld camera. Enabling this option may not be necessary if the images were shot using a tripod.
You can preview the effects of these settings right within the dialog box.
- Sometimes, after the exposure-bracketed images are merged, some areas in the HDR image may appear unnaturally semi-transparent. Select one of the following deghosting option in the HDR Merge Preview dialog box to correct these anomalies: None, Low, Medium, or High. Try Low deghosting first to obtain a clean merged image. Try higher settings if necessary.
Low: Cures little or minor movement between frames
Medium: Cures considerable movement between frames
High: Cures high movement between frames
You can preview the effect of these settings right within the dialog box. If necessary, choose to view the deghost overlay.
