The image on Flickr is NOT "true" high dynamic range. The youtube video youtu.be/1dVNZY_p96w contains a still of this image in "true" HDR, which is not the same thing as photography's definition of HDR. (You need to view the YouTube video on an HDR TV/monitor in order to see the proper colors for the wide color gamut and contrast) This YouTube video is unlike HDR in normal photography where wide colors and highlights are compressed into an SDR image, instead in true HDR the large ranges are kept. This still image was created as a YouTube video due to many HDR TVs not supporting any HDR image formats but most smart TVs support YouTube with its HDR video content... Raw DNG image from the camera to the processed HDR conversion was performed using DaVinci Resolve color grading software. The R|Z568M Nixie Tube is a revival of an antique technology: rediscovered, hand crafted, and made brand new by Dalibor Farny. Previously, no one was making any nixie tubes and the process was becoming a lost art. Thankfully due to much interest by hobbyists and enthusiasts both with and without technical knowledge of high voltage electronics, the nixie tube has made a comeback due to it's beautiful aesthetics and the fun of learning the design of power electronics. One can be a teenager or even an adult with an interest and buy a premade kit, or one can be an expert at electronics and design their own clock circuit & power supply from scratch. That is the beauty of such a simple yet complex device. Nowadays most use micro-controllers to run such nixie tube clocks allowing for people to learn programming too and for more features to be packed into such displays. The R|Z568M Nixie Tube is one of the largest known nixie tubes measuring in at a symbol height of 50 mm (2 inches) and a glass diameter of 50 mm (2 inches). The total height including the glass and the base is 125 mm (4.9 inches) and the total diameter is 53 mm (2.1 inches). This is a huge beast of a nixie tube: both suitably bright and large enough for someone like me to read it across their room without their glasses on. The pleasant orange glow of the neon dimly lights a small room at night in darkness. There is a beautiful halo of blue almost bordering on purple violet light around each lit digit. This is from the mercury vapors being excited by the high voltage which helps ignite the neon around the metal digits. The mercury allows the nixie tube to last a long life: over 20 years or 200.000 hours running 24/7. To see the manufacturing process watch it here: www.youtube.com/watch?v=wxL4ElboiuA Also visit Dalibor Farny's website (which is a work of art in and of itself with it's animated nixie tubes as you scroll to read): www.daliborfarny.com/ This nixie tube is being used in a single digit Nixie Tube clock and being run at just under 1 watt. It works by cycling through the tens place of the hours, then then ones place of the hours, then the tens place of the minutes, and finally the ones place of the minutes. There is a brief pause between the start and end of the cycle allowing you to tell which numbers are at the beginning. The use of the single digit nixie tube clock is twofold: mostly to save money (the R|Z568M costs €135.00 without shipping or taxes!) and because it allows for more thorough cycling through all the available digits within the bulb thereby reducing the risk of cathode poisoning. In a multiple digit nixie tube clock, the tens place for the hours only alternates between the numbers 0, 1, and 2 leading to much higher uneven wear and tear on the device. This photo is in 3D crossview. You cross your eyes while keeping the screen centered and it should become one image at the center in 3D.
