We have featured several practical camera apps that allow you to capture HDR photos with iPhone like HDR Foto. If you want to capture HDR videos, the iPhone app Flare should be a nice solution.
Flare is an innovative video app developed by Alaric Cole, and designed to offer you an entirely way to record HDR videos. The iPhone features simple user interface and intuitive controls. All the effects are live with your video. You can tap and drag on the screen for independent focus and exposure, or pinch to zoom the video, while double tap will easily lock WB, exposure and focus. When finishing your great work, you can also share full-quality videos with friends via Facebook, Twitter, YouTube, Tumblr, Flickr and more.
Flare with a size of 4.2 MB is compatible with iPhone 3GS/4, iPod touch 4th and iPad 2 running iOS 4.1 or later. At present, the iPhone app is free for a limited time. If you’re interested, jump to App Store for more details.
