Take better iPhone photos in low light with Cortex Camera
The iPhone 4S’ camera does an admirable job in a variety of lighting conditions, particularly when you remember that the device is a phone first, and a camera second. Still, if you find yourself shooting in low-light situations, you probably have noticed that your photos look blurry or grainy. Cortex Camera is a $2.99 app that can reduce this graininess or noise when shooting in low light. Here’s how it works:
Instead of taking a single, still photo, Cortex Camera actually captures a short video when you hit the shutter button. Thus, you will need to hold your iPhone still during the 3 seconds or so when Cortex Camera is taking this video, or use a tripod. After another few seconds of processing, Cortex Camera merges 100 frames of video into a single image, saving it to your iPhone’s Camera Roll. You can tap to focus and pinch to zoom.

In my experience, I found that Cortex Camera greatly reduced noise in low-light conditions. And I was able to get crisp shots without the need for a stand or tripod. Photos taken with Cortex Camera are a bit narrower than what you get from the iPhone 4S’ camera. For more comparisons, check out this page from Cortex Camera.[Read more]
