iOS: If you’ve ever tried taking low-light images with a phone or tablet, you know they usually feature lots of noise and grain. Cortex Camera solves this problem with a unique take on long-exposure photography.
Cortex Camera looks like any other photography app at first, but when you hit the shutter button, a progress bar asks you to hold the camera steady for about three seconds. This actually isn’t a long-exposure photograph, but rather a video capture that provides the app with over 100 frames to build a final image.
The results are somewhat inconsistent, and it might take a few tries and a steady hand to get it right. When it works, the image is significantly cleaner than a standard photo. The app is $2.99 and works only on the iPhone 4S, iPad 2 and new iPad.
