In brief: An online article by Uwe Agnes, editor-in-chief of Film & TV Kamera, examined the ARRI ALEXA 35.
Key specifications and workflow:
- Image pipeline: The camera introduced greater dynamic range, improved low-light performance and richer colour reproduction. Two central features were REVEAL Color Science, tuned for the new sensor, and ARRI Textures, which offered selectable image textures.
- Dynamic range and sensitivity: ARRI specified 17 stops of dynamic range and an exposure-index range from EI 160 to 6400. Stray-light suppression was intended to retain the available contrast range for demanding HDR capture.
- REVEAL Color Science: The processing chain included an improved debayer algorithm, a new colour engine and colour space, LogC4 encoding and LogC4 LUTs. The article described REVEAL as backwards compatible.
- Creative control: ARRI Textures let filmmakers adjust image character beyond the fixed standard textures used by earlier ALEXA cameras, changing attributes such as grain, contrast and detail response.
- Operation and accessories: The ALEXA 35 combined processing features from larger ALEXA systems with a body closer to the ALEXA Mini. It supported 19 recording formats, in-camera downsampling and anamorphic de-squeezing. ARRI’s Live Link Metadata plugin could pass lens and real-time streaming metadata to Unreal Engine for mixed-reality and VR production.
Further reading: The full technical discussion was published by Film & TV Kamera. Camera behaviour, recording formats and metadata integration should be tested with the intended lenses, media and downstream pipeline before production.
