To understand how ARRIRAW works and what makes it different from other raw formats, it helps to go straight to the source. In ARRI Academy’s official Certified Online Training for Camera Systems course, which is only available online at MZed, ARRI’s senior trainer Florian Rettich distills the complicated subject of raw recording in a way we can all understand. Even if you’re not shooting with ARRI cameras, this lesson is an enlightening dive into camera sensors and photosites, bit depth, data compression, and color. There’s a lot to learn and the knowledge will help you grasp the technology inside cameras today. ARRIRAW – Photosites, sensors, and analog to digital converters To better explain ARRIRAW instructor Florian first gives a basic introduction to photosites and how they react to changes in light. You may already know this to some degree, but it’s still a good refresher. The way Florian explains the digital imaging process is easy to understand for those of us who aren’t already seasoned pixel peepers. So, all digital cameras have sensors that convert light into an electric charge, which then gets digitized and processed into data. But the way they go about that process differs. Image source: ARRI First let’s only think about light itself, before we add color to the mix. If you think of photosites on a sensor as buckets of light, then each bucket is white when it is completely full of light, and black when it receives no light. You could also use the...
