Development History in Images
These clips were shot over the course of around 18 months of development. Some of the periodic developments improved image quality eg. by reducing noise, but some tweaks didn't make the image noticeably better to any significant degree so please be aware that this collection of clips demonstrate technical snapshots relating to software and hardware development only. Nothing was shot to highlight specific aspects of the camera's development, rather, we wanted to test and evaluate its operating processes in various environments that happened to be available to us during particular times. The footage is all 1080p - some later clips were shot in UHD mode but processed at 1080p.
In the beginning we were borrowing lenses, then we started buying old Nikon photography primes for shooting with the AXIOM Alpha prototype, but over the years we have acquired a selection of old Contax Yashica, M42, Canon and Nikon lenses like the the Zeiss 50mm F1.4 or Distagon 35mm F1.4 and 85mm F1.4. We haven't used any real cinema lens with the AXIOM Beta up to this point as we didn't feel that our test-shots would justify their outlay. Note that all AXIOM Beta developer kits currently use no optical low pass filter and have an infra-red cut-off filter screwed onto the lens. However, our integrating an infra-red filter into the lens mount in the future is planned. In addition, a new optical low pass filter module option will be offered but as yet we're not sure when.

First HDR Footage
The image sensor datasheet declares 10 f-stops native dynamic range but a so called Piecewise Linear Response (PLR) High Dynamic Range (HDR) mode is also mentioned. We've done initial tests with this mode and found that it allowed us to get quite a few additional stops dynamic range out of the image sensor, which is very promising. PLR can make individual sensels (pixels on an image sensor) less light sensitive based on their saturation value during each exposure cycle. In other words, highlights can be tuned to contain a predefined additional number of f-stops. Trust is a Shakespearean short film directed by Juliana Neuhuber and the below clip was the first footage shot with the AXIOM Beta's PLR HDR mode turned on. While the settings might not have been 100% optimal at this point, and while we felt there may still be some room for improvement, the results were better than expected. A single response curve knee-point was used for the time being - in addition the image sensor supports the incorporation of a second knee-point, so, dynamic range increases in the highlights can be tuned for further improvement.
