Are there any tools out there to automatically level an image?
Are there some apps that will automatically guess at how to straighten thousands of photos?
In other words, if I have a lot of photos with non-horizontal horizons, is there an app or plug-in that will go through them all and make an educated guess and straighten them automatically? Alternatively, an app that is semi-automated, i.e. asks me for help when it has a low degree of confidence.
