A method and system. A base photographic image of a scene is combined with N additional photographic images of the scene to form a composite image including M discrete light sources (N&#x2265;2; M&#x2265;N). The scene in the base image is exposed to ambient light. 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. 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. The composite image includes a region surrounding each discrete light source and has an area that correlates with an intensity of light from the discrete light source surrounded by the region. The intensity of light is the intensity at the discrete light source where the light is emitted.

In an approach for utilizing photographic metadata for automated photographic setup, a computer receives photographic metadata. The photographic metadata is contained within an image file. The computer transmits configuration information to one or more photographic devices in a photographic setup. The configuration information is based on the photographic metadata. The computer receives a configuration update from the one or more photographic devices in the photographic setup. The computer determines whether the one or more photographic devices in the photographic setup are configured correctly, based on at least comparing the configuration update to the photographic metadata.

Utilizing metadata for automated photographic setup

A method and system for processing light sources. A base photographic image of a scene is combined with N additional photographic images of the scene to form a composite image including M discrete light sources (N&#x2265;2; M&#x2265;N). The scene in the base image is exposed to ambient light. 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. 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. The composite image is displayed on a display device, depicting a region surrounding each discrete light source and having an area that correlates with an intensity of light from the discrete light source surrounded by the region.

A method for capturing three-dimensional photographic lighting of a spherical lighting device is described. Calculation of boundaries of the spherical lighting device based on lighting properties of at least one light source in a set location of the spherical lighting device is performed. A mapping of multitude points of the spherical lighting device to three-dimensional vectors of at least one camera device using a logical grid is performed. A measurement of brightness of the logical grid of the spherical lighting device is performed. The method further comprises determining brightest grid point of the logical grid of the spherical lighting device, wherein the brightest grid point of the logical grid is measured within a region brightness of the spherical lighting device. The method further comprises calculating the region of brightness of the spherical lighting device based on the determined brightest grid point of the logical grid.

Spherical lighting device with backlighting coronal ring

A method and system for processing light sources found in images. A base photographic image of a scene is combined with N additional photographic images of the scene to form a composite image including M discrete light sources (N&#x2267;2; M&#x2267;N). The scene in the base image is exposed to ambient light. 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. 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. The composite image is displayed on a display device, depicting a region surrounding each discrete light source and having an area that correlates with an intensity of light from the discrete light source surrounded by the region.

In an approach for collecting and storing photographic metadata, a computer receives a file containing an image. The computer receives photographic metadata from one or more photographic devices. The one or more photographic devices include at least one or more illumination devices. The one or more photographic devices are utilized to create the image. The received photographic metadata includes at least specifications of the one or more photographic devices. The computer stores the received photographic metadata in association with the received file.
