I am experiencing a size photo limitation when I try to apply a FilmPack setting.
For a very large photo (panoramic), the filter is not applied. The plugin opens, the settings are correctly displayed, but when applying to the photo and going back to Photoshop, the filter is not applied.
If I reduce the size of the photo, the plugin works as expected.
It seems that a size of 20,000 pixels on one side represents a problem for the plugin.
