State of the ART Technology

ARRI Imaging Technology

Each component of the D-21 and D-21 HD 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 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 Technol- ogy (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.

AIT also ensures that crews can concentrate on the creative aspects of making images, by automating many of the technical aspects. The D-21 and D-21 HD have, for instance, an automated black balancing circuit (Correlated Double Sampling - CDS), which continuously calibrates the black level of each pixel in each frame without any user intervention. 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 and D-21 HD produce 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.

ARRIFLEX D-21 HD specifications

The ARRI ARRIFLEX D-21 HD is a distinguished digital cinematography camera that has made remarkable strides in the film industry since its introduction. Designed for professional filmmakers, it combines traditional film aesthetics with modern digital technology, making it a compelling choice for various cinematic endeavors.

One of the most notable features of the D-21 is its image quality. The camera is equipped with a Super 35mm-sized sensor, which is pivotal in achieving the characteristic depth of field and wide field of view synonymous with 35mm film. This sensor allows filmmakers to exploit the rich visual language that has been a hallmark of high-end cinema for decades.

To ensure maximum flexibility and integration in post-production, the D-21 captures images in a high-definition format with a resolution of up to 1920 x 1080 pixels. This resolution provides filmmakers with the ability to work with detailed and vibrant footage, making it suitable for various distribution formats, including theatrical releases and broadcasting.

The D-21 is also notable for its superior dynamic range, which extends the capabilities of the camera in capturing details in both highlights and shadows. This feature is particularly beneficial for filmmakers working in challenging lighting scenarios, as it permits greater creative latitude during the shoot and post-processing.

In terms of technology, the D-21 incorporates several advanced features. One such feature is its unique color processing system, which allows for precise control over color grading. Filmmakers can capture the scene with accurate color reproduction, thus minimizing the amount of post-production color correction required.

Moreover, the camera supports a modular design, enabling customization to fit various shooting styles and requirements. This includes interchangeable lenses, allowing filmmakers to utilize different focal lengths and depths of field without restriction.

The ergonomic design of the D-21 makes it user-friendly, accommodating the needs of professional crews during long shooting days. It is compatible with a range of accessories such as matte boxes, follow focus systems, and wireless monitoring solutions.

Overall, the ARRI ARRIFLEX D-21 HD stands as a bridge between traditional film and the digital future. Its combination of superb image quality, advanced technology, and a user-centric design cements its position as a preferred choice for many cinematographers striving for visual excellence in their storytelling.
