afterIf you are experiencing some poor low light performance with your stock camera app you may want to check out this modded OnePlus One camera app. CameraNext is a moddified version of the Color OS camera. The app includes a 16 and 32 second shutter delay which helps with low light performance immensely. You will need root to replace your stock camera app if you are on CM11s. Your camera must support the slow shutter scene mode. To use this you will change the scene mode to "slow shutter" and then choose your preferred shutter speed. The longer the exposure the better the low light performance. Head to the link below to grab this app.
