Whereas on a standard display everything below a certain brightness is the same shade of black, an HDR TV's display range goes further, allowing you to tell the difference between something that's really really dark, and something that's just dark. The improvements you'll see with an HDR image compared to a normal image are numerous. HDR creates a wider gamut of colors, allowing for a more vivid image The end result, an image with more contrast between its lightest and darkest areas is the same, but instead of combining separate images this effect is produced using better camera technology to capture the best possible footage in the first place. So although it might share a name and common points with photography, clearly HDR video is different to smartphone photography. It all has to do with the way an image is displayed on the screen and the source content used to do it. Yes, you're still getting an expanded color gamut and contrast ratio when it comes to video, but you're not doing it by combining several images or videos. So while the first stop produces an extremely dark image, the last result is exceptionally bright, lending better luminosity to the final portmanteau photo. These are called stops, and the amount of light is doubled from one to the next. Separate photos are taken at different exposures during the process. But the way they work is slightly different.įor example, high-end cameras and recent smartphone apps utilize HDR by combining several photos taken during a single burst of many photos. Both result in images that have a greater contrast between light and dark. So let's clear up some confusion: the kind of high dynamic range that your HDR TV is capable of shouldn't be confused with the HDR photography options that have recently been added to smartphone cameras.
