“Cortex Camera Takes Great Low Light iPhone Photos”
“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.”
Tired of the grainy photos you get when using your device’s camera in low light? Cortex camera combines dozens of images to create a sharp image without the low-quality noise that shows up when using the default camera. Please note that your subject must be still during exposure, which takes 2-10 seconds.

Supported devices are iPhone 4/4S/5, iPad 2 and 3, and iPod touch 4G and 5G. Requires iOS 5 or above.
Image resolution varies depending on which device you’re using:
iPhone 5: up to 12 megapixels
iPhone 4S, iPad 3, and iPod touch 5G: up to 8 megapixels
iPad 2: 3.5 megapixels
iPhone 4 and iPod touch 4G: 2 megapixels
Q: How does this work?
A: It’s widely known that increasing exposure time provides more light to the sensor and decreases image noise. The problem has been that increasing exposure time makes images more blurry unless a tripod is used, which is very inconvenient. This app gets around this limitation by taking full advantage of your device’s powerful hardware to compensate for the motion of the camera during exposure. It also brings sophisticated algorithms to mobile devices that can combine multiple frames to increase resolution.
Q: Can Cortex Camera take pictures of subjects that are in motion?
A: No. The scene you’re shooting must be still during exposure, which takes 2 - 10 seconds depending on which device you’re using and the resolution of the photo. However, if you like motion blur effects, Cortex Camera generates interesting photos of subjects in motion.
Q: Does Cortex Camera require a tripod?
A: No. Cortex Camera automatically aligns frames and can compensate for normal amounts of shaking when the camera is being held still.
Q: Why are my images slightly “zoomed in” compared to the default camera?
A: Cortex Camera uses video data, which on most devices has a smaller field of view (or is slightly “zoomed in”) compared to still photos. You can see a similar zooming effect when comparing videos to still photos taken with the default camera.
Q: Why do the standard camera photos look so ugly in your screenshots? My iPhone pictures never look that bad.
A: In order to illustrate the difference between Cortex Camera and the regular camera, the images in the screenshots are zoomed to 100% and then cropped to fit the size of a screenshot. In addition, the photos are taken in low light conditions. Take a photo with your phone in low light and view it at 100% zoom -- it will look the same.
