Hi!
In 2009 my father used to use a arcsoft-software; after that he switched to Picasa (Windows) and now to Shotwell, Ubuntu 12.04.
I dont know if he used any other software to rotate the pictures, but its a fact that all photos till 2009-11-11 are displayed in wrong orientation (in any program). After 2009-11-11 its ok (with a few exceptions).
My question is, how can i display all photos in right orientation (in all programs + WDTV Live on his TV).
Is there an EXIF-Tag, that applications lets rotate the photos automatically by the orientation tag? And others not?
I'm very desperated...hope you can help me - there are over 20 000 photos to process and dont have a clue and even not enough time...
Thanks in advance

ExifTool GUI (https://exiftool.org/gui/) allows you to rotate JPEG images according to the EXIF orientation tag. This may do what you want for at least some of the images.

Thanks, that worked for all files up from 2009-11-11.
Do you have a proposal for rotating the photos before that date?
If they don't have orientation information, then they will have to be rotated by hand using an image editor (with a lossless rotation feature).
