This issue is being caused by EXIF data in the image that is there when shot on a mobile phone. The solution to this is a multi step process.

  1. Load image from user
  2. Send image data to Pillow
  3. Manipulate image in Pillow if EXIF data exists
  4. Save Pillow image in S3
  5. Make sure model updates with Image data
