When I photograph the SpyderCHECKR 24 target in landscape orientation, the software will sometimes correct the orientation, but other times it will not. What is the secret to making this work?
Always crop the image to the black border on the SpyderCHECKR 24.
That way the auto-rotate function can do its job. Also, be sure to rotate the target image until the SpyderCHECKR 24 is vertical or horizontal, not at an angle.
