FlashShot is a simple app that creates silly photos of objects using flash light. Like you use any camera app, point to a scene you want to capture, press the "Take Photo" button, and stay put for a moment until the app finishes taking a burst shot with the flash fired and processing it. Photos are saved in the "FlashShot" album of your camera roll.
Since it requires flash and uses the new raw photo format for photo processing, the app runs on the iPhone 6s/6s Plus, iPhone 7/7 Plus, iPhone SE, and iPad Pro running iOS 10; if run on any other model and/or iOS version, it will show the error message about the features it is missing.
