Capturing photographs with an iPhone during night time is possible with the app - SlowShutter. This photo is "SOOC" (Straight Out Of Camera) - I only added a frame. In SlowShutter I dialed in a shutter speed of 1/4 sec and an exposure of -0.75. The partly visible track and the green light adds a special atmosphere of solitude and danger.
Another photo from the same walk with my dog. With a slow shutter speed of 1 sec and the exposure set to HDR, I achieved a "flash light in the dark night" scene with kind of a looming feeling.
