# 1/ Read EXIF orientation flag
identify -format "%[EXIF:orientation]" myimage.jpg

# NOTE: jhead can be used too
# see http://www.sentex.net/~mwandel/jhead/
jhead -exifmap myimage.jpg | grep Ori

# 2/ Remove EXIF orientation
#    i.e. rotate the image accordingly and reset the orientation
#    flag to 1 (default, i.e. origin = TopLeft)
