According to Adobe, “The new HDR mode works by automatically scanning the scene to determine the correct exposure range and then capturing three DNG files which are then automatically aligned, merged, deghosted, and tonemapped in the app. You get a 16-bit floating point DNG, with all of the benefits of both an HDR and a raw photo, which is processed by the same algorithms with the same quality as the HDR technology built into Adobe Camera Raw and Lightroom.”
For those unfamiliar, HDR images basically combines multiple photos taken in different exposures that results in an image with an incredible dynamic range. There are apps out there that help with HDR capture, and some default camera apps, such as the one on iOS, also supports HDR capture.
However Adobe is claiming that their solution is better compared to most as images are captured in the Raw format and that it can capture more than one image, meaning that the dynamic range is better. Whether or not you agree with this assessment is another story, but the updated app is now available for download for both iOS and Android devices.
