“Cortex Camera Takes Great Low Light iPhone Photos”-Lifehacker“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.”-CNETYou knew the camera on your iPhone or iPad was good, but you never knew it could be this good! Cortex camera takes your photos to the next level by effortlessly combining dozens of images to create a sharp, noise-free image. Please note that for best results your subject must be still during exposure, which takes 2-10 seconds.Image resolution varies depending on which device you’re using:iPhone 5, 5S, 6, 6+: 12.5 megapixelsiPhone 4S, iPad 3, and iPod touch 5G: 8 megapixelsiPad 2: 2 megapixelsMini FAQQ: How does this work?A: As with any camera, increasing exposure time on an iPhone camera provides more light to the sensor and decreases image noise. The usual problem with increasing exposure time is that it 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: Cortex Camera is designed to shoot scenes that are still during exposure, which takes 2 - 10 seconds depending on which device you’re using. However, Cortex Camera will optionally replace blurry regions of the final image with the first frame. You can turn this feature off if you want to capture motion blur effects.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 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. Although iPhones have excellent cameras, all mobile devices have to make trade-offs that make it very difficult to avoid noise with a short exposure time in low light.Follow @CortexCamera on twitter for more Cortex Camera goodness!
