Outputting UHD broadens the distribution options for the superior image quality that has helped make AMIRA, and ALEXA, such a success. The wide, 14+-stop dynamic range remains unaltered, as does the accurate colorimetry, natural skin tones, and organic look and feel. By making that high-quality image data coming out of the sensor compatible with higher spatial resolution formats, the UHD upgrade answers the concerns of certain regions and productions about a 4K future, allowing AMIRA to be used on any project, no matter what deliverables are required. Wildlife cinematographer Rolf Steinmann, who was nominated for an Emmy ® Award this year in recognition of his work with ALEXA on the BBC’s Wild Arabia series, is currently using his AMIRA on a movie for Disney Nature. He comments, "For cameramen like me who own their gear, the UHD upgrade is a great way to stay future-proof. From now on when there's pressure from the production side to deliver UHD, I can continue to work with AMIRA and won't have to compromise on image quality or on the camera's robustness and reliability." The ALEXA/AMIRA sensor has repeatedly proved its ability to deliver outstanding image quality for the 4K or even IMAX theatrical releases of high-end feature films such as Gravity, Maleficent and Iron Man 3 . This proves that the ALEXA and AMIRA camera systems are already future-proof and more than suitable for the next generation of distribution formats. For major feature films, an up-sample to 4K can be carried out after visual effects and other postproduction tasks have been completed at 2K resolution. For certain fast-paced AMIRA productions, however, there may not be the time or resources for 3D LUT LOOKS UHD UP-SAMPLE DEBAYER SENSOR Live UHD Output 6G-SDI ProRes UHD on CFast 2.0 Technology Demo AMIRA Image Path SAME GREAT IMAGE QUALITY IN-CAMERA PROCESSING such processes in post, which is why a 4K or UHD output direct from the camera has been requested. AMIRA’s UHD output utilizes the same efficient 1.2x up-sample filter that allows ALEXA’s Open Gate mode to optimize the camera’s image performance for 4K distribution, as well as the same best-in-class sensor pixels. The up-sample to UHD happens in camera, and in real time.
