Our cameras can capture a significantly greater light range than can be displayed on any computer, projector, or tablet screen. Where other cameras would just see white or would see distorted highlights we see detail and accurate color all the way through the light range. Using our adaptive tone-mappers we can see accurate colors and details not only up into the highlights, but also down into the lowlights. Check out this FAQ about displaying HDR data for more info.
The following videos are a small window into what is capable with amp technology. Some videos were captured at 1080p using our early prototype and others with our new Gen2 camera at 720p. Check the video descriptions for additional information and feel free to contact us if you have questions about a specific video you see here.

ampHDR: Metal Foundry
This video is made up of shots taken with our amp camera at a metal foundry, and we captured several of the processes involved in creating various metal ingots and blocks. Some of the shots in this video show molten magnesium alloys, which are typically much too bright to capture with any standard camera, but our amp camera captures an incredible amount of color and contrast detail. The "pig cast" clip shows a direct comparison to a standard camera used in most foundries. This is a great way to see the additional range that amp is capable of capturing. All the amp camera footage shown here was captured from the real-time tone mapped video stream (from the HDMI output port on the amp camera). No post-processing at all was performed on this footage.
ampHDR: Laser Heating
This video was taken using the Gen2 ampHDR video camera. amp is a High-Dynamic Range video camera that can capture over 18 photographic stops of light range -- far more than any typical camera. For this video, we recorded different materials as they were melted with a high-power laser. The laser is not visible in these videos, but the materials all glow very brightly, and some of them produce flames and smoke while the laser is heating them. For each material, we shot video using both a false-color (luminance only) mapping and a true-color realtime tonemapped video output. False color is nice because it shows the true luminance range in each scene, without any alteration of the video data (good for scientific research). And the true color video is nice because it shows actual color changes in the materials and gives a true view of what these materials actually look like as they are heated with the laser.

TEDxABQ amp Reveals Reality
This HDR video debuted as part of our TEDxABQ 2012 talk, "Reveals Reality" by Nora Tocci.
This short video was produced with amp camera's real-time, tonemapped outputs. These custom, real-time TMOs include ampTrueColor and ampPureLumen. The entire video was captured via the HDMI output using 3rd party video recording equipment.
Shot by local Director of Photography, John Golden Britt, with Ian Simon and edited by Randy McComas.

amp: Getting the Whole Picture
"amp: Getting the Whole Picture" is a brief video that shows various ways to view amp HDR footage. It's impossible to display amp HDR footage in its raw format, because today's displays (LCD screens, plasma TVs, digital projectors, etc.) do not have enough dynamic range to show all the data we capture. So we use a few different methods to show the extraordinary range of light-levels that we capture.
The amp prototype camera used to capture this footage comprises three SI-1920 camera sensors, to capture high, medium, and low exposure images for each frame of video.
To demonstrate the amount of dynamic range that the amp system adds to the standard SI-1920 camera, we show comparisons between the amp footage and the same footage seen with the medium-exposure SI-1920 sensor, or what a "typical" camera might see for each scene.
Working together with Erik Reinhard, we have developed a new video tone map operator (TMO) to provide real-time, natural-looking output from our next-generation cameras (via HDMI).
This new fully-automated video TMO, which we call the Kiser-Reinhard TMO, gets applied to both the raw SI-1920 (single sensor) videos and to the amp HDR videos. On a properly-calibrated video monitor or projector, you can see the extension of color and details, as well as the removal of significant noise, both up into the highest highlights and down into the darkest lowlights of the scenes.

AMP Melting Snow
This video shows how a single frame of AMP HDR video can be tonemapped many different ways, giving the artist complete tone control over the image. A couple of selected tonemappers are then applied to the entire video.
"Melting Snow" is test footage that shows the distinct difference between creating an HDR image (which cannot be displayed on today's computer or TV monitors) and the tonemapping process (which essentially "crushes" all the HDR data down to an image that can be displayed on a monitor). This "data crushing" process is very artistic, and it's straightforward to use commercially-available software to produce a variety of tonemapped looks running from very natural, to washed out, to completely cartoon-like.
In addition to putting out a "natural" tonemapped video stream via HDMI, the AMP camera generates and saves a true HDR image for every frame in a video, with complete color tone information from the darkest areas of the scene all the way up to the brightest areas. After the AMP camera produces the HDR frames, it is up to the artist to choose how to tonemap the frames for display.

A Versatile HDR Video Production System
"A Versatile HDR Video Production System". Contrast Optical Design & Engineering, Inc. (CODE) and the Advanced Graphics Lab present their SIGGRAPH 2011 submission video that accompanies the Technical Paper of the same name. This camera system captures a true HDR image for every frame of video, and then it's up to the user to tonemap it however they want. We used a variety of commercially-available tonemappers with the video data shown here.
AMP Digital Video
A fun video that introduces the AMP Camera Technology and gives a sneak preview of the GEN II camera features. AMP captures three images with the exact same exposure time, at the exact same moment in time. A custom blending algorithm is used to combine the images to produce a true HDR image for each frame in the video. Of course, we can't display true HDR images (yet) so tonemapping is left to the user. For this video, we chose a wide variety of commercially-available tonemappers, just to get the idea across that all the HDR data really is there for every frame.
