I don’t know about others, but my cameras’ preview images do not contain any useful metadata, such as orientation of the exposure.
I’ve now implemented this feature by examining the RAW orientation and losslessly rotating the camera preview JPEG according to it.
Now, the JPEG preview of vertical images should be vertical as well.
