doing some photography in the darkness would require a long-time-exposure with three to five seconds. The professional mode in Lightroom's camera does just allow one second at the maximum to capture, which is by far not enough to capture at night. Today it looks like the image that I sent as attachment, on which you can see a lot of noise which was caused by the short exposure time, that is one second at the maximum. to avoid this, my suggestion is, to allow more seconds for the exposure time.
