Photographers looked to film manufacturers to design new film stocks with improved response, or continued to shoot in black and white to use tone mapping methods. The film was processed in a manner similar to color films , and each layer produced a different color. The concept of neighborhood tone mapping was applied to video cameras in by a group from the Technion in Israel, led by Oliver Hilsenrath and Yehoshua Y.
Technion researchers filed for a patent on this concept in , [38] and several related patents in and This process is known as bracketing used for a video stream. In , another commercial medical camera producing an HDR video image, by the Technion. Modern HDR imaging uses a completely different approach, based on making a high-dynamic-range luminance or light map using only global image operations across the entire image , and then tone mapping the result.
Global HDR was first introduced in [1] resulting in a mathematical theory of differently exposed pictures of the same subject matter that was published in by Steve Mann and Rosalind Picard. It consisted of four film images of the space shuttle at night that were digitally composited with additional digital graphic elements.
The advent of consumer digital cameras produced a new demand for HDR imaging to improve the light response of digital camera sensors, which had a much smaller dynamic range than film. Second, convert this image array, using local neighborhood processing tone-remapping, etc. The image array generated by the first step of Mann's process is called a lightspace image , lightspace picture , or radiance map.
Another benefit of global-HDR imaging is that it provides access to the intermediate light or radiance map, which has been used for computer vision , and other image processing operations. In February , the Dynamic Ranger technique was demonstrated, using multiple photos with different exposure levels to accomplish high dynamic range similar to the naked eye. In the early s, several scholarly research efforts used consumer-grade sensors and cameras. The "x" channel can be merged with the normal channel in post production software.
The Arri Alexa camera uses a dual-gain architecture to generate an HDR image from two exposures captured at the same time.
With the advent of low-cost consumer digital cameras, many amateurs began posting tone-mapped HDR time-lapse videos on the Internet, essentially a sequence of still photographs in quick succession. In , the independent studio Soviet Montage produced an example of HDR video from disparately exposed video streams using a beam splitter and consumer grade HD video cameras.
