My favorite high resolution photo app
On this new version 1.97, cortex has been greatly improved over previous updates. Image quality is top notch at the moment and I enjoy using this app for generating crisp clear photos during the day and during the night. Take in mind that a larger image will look better when printed if anybody ever print their iPhone photos. This app is crisp and clean but you do have to hold still, I generally and hold firmly or use a small tripod when shooting landscapes with my iPhone. I highly recommend cortex camera for low noise images and general photography. On the iPhone 6s and 6S plus, images are equivalent to a 27.4 megapixel camera. I then will take that image and reduce it to a 20 megapixel in size to get the best clarity and overall image quality. I usually resize my images in the app called Big Photo.
