Lightmatic allows you to capture motion as a single event. Tap the shutter button to open it up and allow some time to pass before closing it. Anything in motion will become a beautiful blur of color while the rest of the image will remain intact. You’ll either need a steady hand or a place to mount your iPhone, otherwise the entire image will blur. You can utilize a set of headphones to open and close the shutter to avoid unnecessary movements. After capturing a photo you’re able to adjust the contrast, brightness, and saturation. The app also includes a timer, grid, and two aspect ratios to choose from.
