Abstract: An approach is provided for performing back-end operations for camera control. In one example, a method includes the following: receiving a user edit via a user interface device that displays an interpretation of a scene at which a camera lens of the camera is pointing, wherein the user edit is based on user input that is associated with a selection region on the user interface device; generating an edits mask based on one or more matching image patches, which are based on the user edit and a high dynamic range (HDR) image generated by the camera; performing one or more tone mapping operations based on the edits mask and the HDR image in order to generate a tone mapped HDR image; and performing one or more metering operations based on the edits mask and the tone mapped HDR image in order to generate metering parameters for frame capturing operations.
