Since more then ten years I use
exiftran to rotate images after getting them from the camera.
Is this step still needed today?
Don't browsers and other image apps rotate the image correctly without running exiftran on the files.
Background on exiftran:
exiftran is a command line utility to transform digital image jpeg images. It can do lossless rotations like jpegtran, but unlike jpegtran it cares about the EXIF data: It can rotate images automatically by checking the exif orientation tag, it updates the exif information if needed (image dimension, orientation), it also rotates the exif thumbnail. It can process multiple images at once.
