This is footage of Orbital ATK’s QM-2 solid rocket booster test taken by NASA’s High Dynamic Range Stereo X (HiDyRS-X) camera. HiDyRS-X records high speed, high dynamic range footage in multiple exposures simultaneously for use in analyzing rocket engine tests. Traditional high speed video cameras are limited to shooting in one exposure at a time, but HiDyRS-X can record multiple high speed video exposures at once, combining them into a high dynamic range video that adequately exposes all areas of the video image for comprehensive analysis.
HiDyRS-X will continue testing at Stennis, while a second prototype of the camera is built with more advanced high dynamic range capabilities, using data gathered from the past few years of experimentation. The second HiDyRS-X prototype will be made with an improved manufacturing process to enhance the alignment capabilities of multiple exposure settings -- a challenge overcome in the first prototype.
HiDyRS-X not only stands as a game changing technology expected to revolutionize propulsion video analysis, but it also stands as a testament to ECI and the power of determined young engineers within NASA. Seasoned NASA employees and recent hires alike have the capacity to significantly contribute to NASA’s research and development goals. ECI’s emphasis on pairing young engineers with innovative industry partners enables technological leaps that would otherwise be impossible.
This is because HDR imaging acquires multiple images at different exposures and applies digital signal processing algorithms to recombine them into a single image that excludes over- and underexposed pixels to improve image quality. The result is an image with more detail than could be captured by a single exposure. HDR imaging effectively increases a camera’s dynamic range and eliminates saturation
Camera exposure will instead be controlled at the chip/pixel level and then integrated into a high-speed video camera. The resulting HDR capability will be easier to install and operate within the SSC test stands because the entire system will be contained within a single camera;

technology that can be used to give us a better world
I don't know about a better world but hopefully my pictures wont look like this anymore
I haven't got around to it, but I want to do a proper analysis, maybe even hire someone in the industry to review some materials. From what I can tell off-hand though, my guess is they developed software (in the 80s before Clementine launched - DoD NAVY SPc) that smooths the landscape as it processes the imaging data. And they've just improved on it over an over.

a reply to: boncho I think it's like you said, I think that they have more detailed cameras but don't want to let the public know otherwise they would have to explain just why their photographs are such crap.
