Simplified lighting compositing

A computer program product, comprising one or more computer readable hardware storage devices having computer readable program code stored therein, said program code containing instructions executable by one or more processors of a computer system to implement a method, said method comprising:

• combining, by the one or more processors, a base image of a scene with N additional images of the scene to form a composite image comprising M discrete light sources, wherein the scene in the base image is exposed to ambient light, wherein the scene of the base image is exposed, in each of the N additional images, to the ambient light and to at least one discrete light source to which the base image is not exposed, wherein the M discrete light sources in the composite image include the discrete light sources to which the scene is exposed in the N additional images, wherein N is at least 2, wherein M is at least N, wherein the composite image comprises a region surrounding each discrete light source and has an area that correlates with an intensity of light emitted by the discrete light source surrounded by the region.

A computer system, comprising one or more processors, one or more memories, and one or more computer readable hardware storage devices, said one or more hardware storage device containing program code executable by the one or more processors via the one or more memories to implement a method, said method comprising:

• combining, by the one or more processors, a base image of a scene with N additional images of the scene to form a composite image comprising M discrete light sources, wherein the scene in the base image is exposed to ambient light, wherein the scene of the base image is exposed, in each of the N additional images, to the ambient light and to at least one discrete light source to which the base image is not exposed, wherein the M discrete light sources in the composite image include the discrete light sources to which the scene is exposed in the N additional images, wherein N is at least 2, and wherein M is at least N, wherein the composite image comprises a region surrounding each discrete light source and has an area that correlates with an intensity of light emitted by the discrete light source surrounded by the region.
