In October, some members of the apertus° team held a two-day AXIOM workshop at the Louis Lumière cinema school, Paris. This is their report (photos by Kevin Théard): As mentioned in the report of the previous workshop , Louis Lumière is a unique school for upcoming cinematographers, where students and teachers work on a deep level of (physical) understanding regarding their tools - investigating both the technical and creative aspects. The latest workshop was organized by Alain Sarlat (... » Read more
apertus° now community and company at the same time The apertus° project has successfully transformed itself from a community-only project to a company-community project. Of course we still are a community but with more responsibility and clearer role definitions. Yet, public perception apparently changed as people primarily perceive us to be a camera manufacturing company when we approach them. Furthermore, the Open Hardware Summit in Philadelphia drew our attention to something rather... » Read more
In this Team Talk Episode: AXIOM Bridge Introduction Watch Video Chapter We applied for an innovation grant to advance a sideproject that we funded as stretch goal in the AXIOM Beta crowdfunding campaign. An open hardware and free software digital video capture PCIe card to stream high bandwidth 4K raw video from an AXIOM Beta to a connected PC - we call it AXIOM Bridge . Update: Unfortunately we did not get the grant. AXIOM Ecosystem Introduction Watch Video Chapter The AXIOM Ecosystem is a... » Read more
Some members of the apertus° team attended the 3rd edition of the Festival Cinema Libre in Hamburg, Germany, to present the apertus° project and the opportunities provided by an open source camera for independent filmmakers. The Cinema Libre Festival, as described on their website , is independent from the film industry and focuses on movies which are self-produced, crowd-funded or were created with no money at all. It offers a very diverse panorama of short and feature films, in various genres... » Read more
In may, a part of the apertus° team gave an AXIOM presentation at the Louis Lumière cinema school. This is their report: It’s a unique school where - as you may call it - they teach “image architecture” (a mix of cinematographer and engineer). We made a two part presentation about open source and its benefits for filmmakers, the AXIOM camera roadmap, followed by a hands-on workshop with the Alpha prototype. We received great feedback from the attendees. It’s really interesting to notice that... » Read more
It was apertus’ first appearance at NAB, the Las Vegas trade show originally named after the National Association of Broadcasters. We only had vague expectations of what would happen at the world’s biggest trade show for cinema gear and film industry supplies. We started our journey with a real ‘American road trip’ after arriving at Los Angeles International from Europe. Our anticipation for the show stretched out during our crossing of the desert after a (naively) unexpected five hour traffic... » Read more
Some of the apertus° team attended the 37th edition of the International Short Film Festival Clermont Ferrand in France to showcase the AXIOM Alpha prototype and the apertus° project in general. As the recently crowd-funded AXIOM Beta is still in development, people attending the festival were able to put their hands on the AXIOM Alpha prototype and become familiar with the concept of sharing the entire technology as open source. Clermont Ferrand Festival Flyer Design From the 2nd - 6th of... » Read more
AXIOM timeline
The AXIOM project has surpassed a number of milestones, and yet there are still new and exciting things happening right now. In order to visualize everything that's taken place in parallel throughout the AXIOM Alpha development, we've created an interactive timeline illustrating the first part of the AXIOM Saga: From the announcement of the AXIOM in Geneva, Switzerland to the commencement of the crowd funding campaign - marking the beginning of the AXIOM Beta development and the end of chapter... » Read more
Last month we got an invitation from Alexander de Villa Robinson to join one of the most important technology festivals in Mexico and present the AXIOM Alpha camera to a Latin American audience at TAG CDMX 2014 . We had some trouble making it happen because the AXIOM Beta development was already ongoing and a lot of work needed to be done. Fortunately the people around the TAG event, notably Cecilia de los Rios and Paulina Torrescano, organized everything including flight, transportation and... » Read more
AXIOM Beta takes shape (literally) When we first announced the AXIOM Beta camera , we had a pretty clear idea of how the camera would be designed from a technical point of view. Nevertheless, it was still quite difficult to show people this vision as it existed only within our imagination. Now we have begun turning our ideas into actual design studies, to be accompanied by illustrated concept images. The first of these concepts is showing the PCB Stack concept for the AXIOM Beta and allows for... » Read more
Particle Collisions We had a couple of great days in Hamburg, heard talks about interesting topics and met a lot of inspirational people. And we were also given a grand tour of the particle accelerators that we were all so "physically attracted" to :) . DESY's primary task, since the research centre was founded in 1959, has been to investigate the smallest particles known at that time.. Over it's five decade operation history, DESY provided essential information and data for solving some of the... » Read more
At the end of this week we will be traveling to Hamburg in order to attend the "Exceptional Hardware & Software Meeting" (EHSM) . It would appear that makers and hackers tend to be physically attracted to large particle collider installations, given that we had our first apertus° first apertus° community meeting in Geneva near the CERN Large Hadron Collider , and now EHSM is held at the DESY (Deutsches Elektronen-Synchrotron - German Electron Synchrotron) operating a particle accelerator... » Read more
The rather unfortunate wiring of the HDMI encoder chip on the Zedboard of AXIOM Alpha makes it impossible to use any full (4:4:4) color mode, because there are just not enough data input lines to transfer a complete pixel. The only modes we can use are those where partial data for two pixels is transmitted and the missing parts are interpolated by the encoder (ADV7511). The mode we started with was the rather strange RGB 2:4:2 mode where pairs of red/green and green/blue are sent and both red... » Read more
Let me start by saying we are very sorry in case we managed to scare you for a second (or maybe a bit longer) :) I hope we did not do any permanent damage to your opinion of us. We did not sell the company and we have no plans to do so. We were actually pretty sure our proposals were considered extreme enough that nobody would take them seriously. So let's summarize what we pulled off this year at the one time of the year when there are no rules (April 1st). On April 1st we posted the following... » Read more
We have now resolved the issues we were facing with HDMI video recorders . It turns out that monitors are capable of synchronising to whatever frequency you are supplying them with, making them very tolerant and usable straight out of the box - even with non standard signals. Recorders on the other hand are a lot less flexible when it comes to the frequency of the supplied input signals. It appears that they will stubbornly refuse to do anything unless the supplied input frequency is perfect... » Read more
Last Friday in Vienna marked the first public presentation of our functional Axiom Alpha prototype. (Ok, so we did actually showcase our prototype earlier at the Photoniks Congress in Berlin , but that was for a predominantly members-only audience). What better location could we have hoped to do so other than at Austria's first hacker/fablab, the Vienna Metalab . Our attempt to summarise our project - the theory surrounding the Axiom camera plans and the prototype - lasted roughly one hour,... » Read more
A report by Oscar Spierenburg We arrived in Berlin the day before the Photonik Congress started, where apertus° proudly presented the biggest development of the AXIOM prototype at the "Make Light" exhibition. I had never visited Berlin. In fact, I'd never visited Germany before. My impressions were quite similar to the image that lots of people had enthusiastically described to me: a youthful, vivid and very dynamic city. Left: Berlin Altes Museum ("Old Museum") | Right: Berlins typical yellow... » Read more
We have made a major development breakthrough enabling real-time Full HD video output via the AXIOM Alpha prototype’s HDMI port. (The final AXIOM camera is planned to have 3G-SDI instead of HDMI interfaces, but for now we are using what is available on the Zedboard development platform). Our current prototype allows us to output progressive 1080p video at up to 60 FPS downscaled from our 4K Super35 image sensor. This represents the completion of a major milestone on our path to the crowd-... » Read more
What does "open" mean? There has been an ongoing community discussion around the level of openness to which apertus° will be willing/able to go with the Axiom. This discussion has lasted for several years up to now. On our website (See: “Why Open Source?” ), we have detailed the problems that openness can introduce with proprietary interfaces. In most cases, developers are forced to sign binding non-disclosure-agreements (NDA) before any technical documentation may be acquired. With this in... » Read more
We have been invited to showcase the Axiom Alpha prototype at the Photonics Congress in Berlin on February the 20th, 2014 . The event itself does not seem to be open to the public but if anyone in that area is interested we can surely schedule a meet up time/place while we are in Berlin (from the 19th - 21st). » Read more
This year you can open one present early: First 4K RAW DNG image from our Axiom Alpha prototype: As we've previously stated, please keep in mind that our sensor calibration and tuning- alongside our image conversion logic development- have just begun and this image represents a camera in a very early developmental state. For example, the image has had no fixed pattern noise corrections or hot pixel compensation applied amongst other things that we just have not had the time to implement yet... » Read more
The second Axiom Alpha prototype unit, now containing a full grade image sensor, is complete and ready for further calibration testing. Please remember that this prototype- housed in a custom enclosure made from laser cut acrylic glass and a wooden base to provide the assembly with greater strength around the tripod mounting plate- is a proof of concept, designed to test the electronics and allow us to capture images in the same manner as with a real camera, under proper lighting conditions... » Read more
This is a combined news update regarding both our hardware and software development progress. As you can see, our work with Axiom Alpha prototype is coming along quite nicely. We’re sure you’ll all be happy to hear that raw still image capture has been working well on our testing board for quite some time now. However as we are still finishing the prototype enclosure, we have not yet carried out many other calibrations and tests - especially considering that the image sensor we’ve installed in... » Read more
On the Road to Pixeltown After a seriously busy month spent programming VHDL for the FPGA (we had a backlash when we discovered a bug in the provided memory AXI slave interfaces, which required a workaround), creating Linux drivers and scripts, testing and establishing workflows, our Zedboard is now fully communicating with the CMV12000 image sensor . We knew this wasn’t going to be a walk in the park, and to explain how complicated it is getting data from the sensor (which probably isn't that... » Read more
After receiving our PCBs for the prototype , we have now started assembling them. Doing so has required a series of complex procedures and multiple runs of hand soldering tiny components or reflow soldering on a hot plate. This has been immediately followed with connectivity testing and interface communication tests. At present, all components have been properly installed and testing/verifying electrical connectivity has indicated that everything is in good working order. On the software side... » Read more
It's about time Today is a major milestone on our path to having a working Axiom Alpha prototype ! After months of designing, routing, checking, double-checking and then revising our designs, we have now placed an order for the final version of the printed circuit boards (PCBs) we will be implementing in our prototype. The Image Sensor Front End (SFE) PCB Top Side. PCB Bottom Side. This 4 layer PCB will act as the bridge between our image sensor: the CMV12000 (providing a native resolution of... » Read more
apertus° is opening up all the internal discussion about the Axiom Alpha prototype to the public and is currently seeking additional hardware developers. Read on to learn why and how. Release Early - or even before that On his blog, Philip Bloom recently wrote : “Please stop bringing out new cameras and stop announcing them. Just go back into your top secret bunkers and concentrate on refining and perfecting your current ones and ideas for your future ones. [...] I am a big fan of announcing... » Read more
