ARRI Imaging Technology

Each component of the D-21 has been purpose-built with one goal in mind: to create the most gorgeous cinematic images possible. Those images are the result of a custom designed CMOS sensor, a carefully crafted optical low pass filter, a powerful imaging hardware engine and advanced image processing algorithms. Having full control of the D-21's imaging chain down to the smallest detail allows an optimization of the whole system far beyond what would be possible with off-the-shelf components. The smart orchestration of all these proprietary components is ARRI Imaging Technology (AIT).

AIT, which is in constant development, combines ground-breaking research and development with knowledge, feedback and suggestions gleaned from an on-going dia- logue with professional filmmakers. AIT provides super sharp, alias-free images through over sampling, a finely tuned optical low pass filter and advanced image reconstruction algorithms.

Image processing advances incorporated into the D-21 include increased sensitiv- ity, with 'linear' HD output ranging between EI 100 and EI 800 equivalent, as well as optimized sharpness and enhanced, film-like color reproduction.

AIT also ensures that crews can concentrate on the creative aspects of making images, by automating many of the technical aspects. The D-21 has, for instance, an automated black balancing circuit (Correlated Double Sampling - CDS), which continu- ously calibrates the black level of each pixel in each frame without any user interven- tion. In addition, an automated Defect Pixel Correction (DPC) guarantees that no single defective pixel will ever be visible. DPC is a highly sophisticated process that analyzes every pixel plus a surrounding pixel field in every frame (for a staggering total of 2.5 billion pixels analyzed each second) in real-time as the camera is running.

Through AIT, the D-21 produces outstanding images with a cinematic look and feel, high contrast, the highest dynamic range and the most film-like color reproduction of any digital motion picture camera.

The D-21 incorporates advanced color science, enabling it to capture a broad dynamic range and reproduce colors faithful to the filmmakers' vision. Its sensor offers an impressive 13 stops of dynamic range, providing the ability to handle highlights and shadows with phenomenal detail. This capability is especially vital for high-contrast scenes often found in cinematography.

Another key characteristic of the D-21 is its modular design, which allows for various configurations to suit different shooting requirements. The camera body can be equipped with numerous accessories, including a wide range of lenses, filters, and external recorders, enhancing its ability to adapt to diverse filmmaking conditions. Additionally, the D-21 supports various recording formats, including 1080p and 720p, allowing for both high-definition and standard workflows.

The camera employs a dual-link HD-SDI output, facilitating real-time monitoring and recording to external devices. This feature is particularly useful during live broadcasts or in demanding production environments where immediate feedback on image quality is critical.

The ARRIFLEX D-21 also incorporates advanced noise reduction technologies, ensuring that low-light performance remains exceptional. This capability allows filmmakers to work in challenging environments and capture stunning visuals without the need for extensive lighting setups.

Durability is another aspect where the D-21 excels. Constructed with robust materials, it can withstand the rigors of professional filmmaking, making it a reliable choice for on-location shooting. Furthermore, the camera is designed to be user-friendly, equipped with intuitive controls that minimize the learning curve for cinematographers.

In conclusion, the ARRI ARRIFLEX D-21 has earned its place in the pantheon of cinematic tools due to its blend of innovative technology and a deep-rooted understanding of the art of filmmaking. Its remarkable features, such as superior image quality, flexible design, and robust performance in various environments, make it a valuable asset in any filmmaker's toolkit.
