What causes a scan of my photos for faces?

[ray.ganong]

Fotobounce will only scan a photo once looking for faces, with one exception.

If you rotate a photo and no faces were already detected for that photo, then Fotobounce will rescan the photo with the new orientation.

we had a question from a user about how to ask Fotobounce to rescan a photo for faces - once the photos have been scanned there is no need to rescan... the science of face detection in photos is not perfect and there are some faces that just don't lend themselves to auto detection. however, if you accidentally deleted some faces then if you edit the photo in any way - resize/crop/adjust color/etc. - then we will rescan the photo.
