1. A machine implemented method, the method comprising:
receiving content that comprises image data for at least a first scene and receiving first metadata that is associated with the first scene, the first metadata specifying how, relative to a first position of a first subject in the first scene, to adapt a playback on a display device having an aspect ratio (AR) that is different than an original aspect ratio, the first scene having been created on an image canvas that has the original aspect ratio; and
adapting output to the aspect ratio of the display device based on the first metadata; further comprising:
receiving distance and position parameters related to a position of a viewer relative to the display device; and
further adapting the output of the first subject to the display device based on the distance and position parameters; and
wherein the content includes a plurality of scenes, including the first scene, and each of the scenes in the plurality of scenes has a determined position for a subject of the corresponding scene, wherein subjects are determined on a scene by scene basis, and wherein adapting for different ARs is done on a scene basis and wherein tone mapping is done on a scene by scene or frame by frame basis for the display device based on what relative portion of an adapted image is labeled as a region of interest, wherein the region of interest includes the first subject, and wherein each scene includes one or more frames.
