The feature is not perfect, but it helps to smooth out the joins between images.
Some notes about this feature:
- The brightness and devignetting adjustments are not automatic, the parameters have to be set manually. Usually I make those adjustments to a panorama add them to the metadata, so that the program picks up the adjustments automatically. Panoramas that have not had brightness/devignetting adjustments added will appear as normal even when you check "Adjust raw image brightness" in the Panorama dialog.
- The "Adjust raw image brightness" checkbox in the Panorama dialog turns both brightness and devignettign adjustment on or off.
- Brightness/devignetting adjustments are made "on the fly" as the images are loaded; the raw images stored on disk are not modified. The raw images stored on disk always remain exactly as downloaded from JPL or Exploratorium.
- Currently, generated images have brightness and devignetting adjustments made at the time they are generated. You will sometimes see images being regenerated automatically during an update when the brightness/devignetting metadata has been updated.
- It is possible to play with the brightness/devignetting parameters of images yourself, but I'll have to document how that's done later.
- Added a "Export Pan Images..." menu option under File->Advanced. This allows you to export the images displayed in a MMB panorama to a directory, so that they can easily be imported into an external program, such as Autostitch. Hidden images are not exported. Currently the export option does ignores which images are selected and exports all images which are visible (I may fix this in the future).
As another example, here is the same view with brightness adjustment and de-vignetting turned on and off:
