Keywords provide a short description of the image content. Tags provide additional information about how the images were acquired. A “sequence” tag means that the same scene was taken several times while changing a parameter, e.g., “sequence: aperture” means that the scene was photographed while changing the aperture (and simultaneously the exposure time), “sequence: scale” means that the object is photographed at decreasing distance to the camera, “sequence: time” means that the scene is photographed at approximately equal time intervals, etc.
