Post production replication of optical processing for digital cinema cameras using metadata

A digital cinema camera for post-production replication of an optical processing for a digital camera configured to capture images, comprising:

• an effects sensor configured to capture an optical effects of the digital cinema camera, wherein the optical effects are applied to raw image data capturing the images including a light source, wherein the light source is emulated with the selected optical effect by setting characteristics of the light source within the images, the characteristics including at least one of position, intensity, and color of the light source;
• a processor configured to receive an optical effects parameter, wherein the optical effects parameter indicates how to apply the optical effects to the raw image data;
• an optical effects data storage unit to store the optical effects and the optical effects parameter as effects metadata,
• wherein the processor marks the effects metadata with time information to associate the effects metadata with the recorded raw image data over time;
• a raw image data storage unit to record the raw image data using a sensor of the digital cinema camera,
• wherein the processor applies the selected optical effect to the raw image data according to the optical effects parameter to create processed image data while preserving the recorded raw image data,
• wherein storing the optical effects and the optical effects parameter as the effects metadata for the recorded raw image data in the optical effects data storage unit while preserving the recorded raw image data in the raw image data storage unit enables the selected optical effect to be applied according to the optical effects parameter to the raw image data, post production;
• and
• a display configured to display the processed image data.
