1. A method of setting a plurality of depth values of a plurality of objects in a scene, comprising: providing a multilayered image having a plurality of layers each depicting one of a plurality of objects in a scene comprising said plurality of objects, each one of said plurality of layers having one of a plurality of depth values defining a plurality of depth differences between said plurality of objects, each one of said plurality of layers is a multi pixel portion of said multilayered image; selecting a depth range; displaying a plurality of layer markers to a user, each one of said plurality of layer markers is indicative of another of said plurality of layers; identifying a user input wherein one of said plurality of layer markers is moved by said user; simultaneously adjusting said plurality of depth values of said plurality of objects according to said user input while maintaining said plurality of depth differences, said adjusting being limited by said depth range; and instructing the generation of an output image depicting said scene so that said plurality of objects having said plurality of adjusted depth values; wherein said plurality of layer markers are plurality of thumbnails of said plurality of objects.
