I have taken pictures from digital cameras and scanned old photos, and edited them with Windows 8 photo. When I try to display the pictures on a digital picture frame, many are rotated incorrectly. Phillips says I must wash them thru paint one at a time to fix this. Are there frames that can read them like the computer does?
Unfortunately, the only way to know for sure whether a digital picture frame will automatically rotate images for you is to try it. To avoid problems, you can rotate your images prior to copying them to the frame for display.
exiftrancan losslessly rotate images based on the Exif orientation tag:
exiftran -abip *.jpg
jheadalso uses the Exif orientation tag:
jhead -autorot *.jpg
To my knowledge,
jpegtrandoes not use the orientation tag:
jpegtran -copy all -rotate 90 -outfile output.jpg input.jpg
However, it does come with a utility
exifautotranthat reads the orientation tag and calls
jpegtranto perform the actual rotation.
Keep backups of the originals. Some tools have been known to corrupt the MakerNotes tags when rotating images.
