Almost all digital cameras save JPEG files with EXIF (Exchangeable Image File) data. Camera settings and scene information are recorded by the camera into the image file. Examples of stored information are shutter speed, date and time a photo was taken, focal length, exposure compensation, metering pattern and if a flash was used.
A directed homography is one based on specifying an orthogonal set of vectors in camera space that define a specific plane.
