Much easier than you think, provided you have necessary equipment. A decent camera, a wide-angle lens, a tripod and a remote control. It’s very important to use the RAW format for the further processing. Concerning the technical parameters:
ISO: you know, that ISO is sensitivity of the captor to the light. The higher is the ISO number, the clearer will be the picture, but of the worse quality. We decided on the regular ISO 200, 350 – maximum.
Focus and Aperture: manual mode and if possible – “infinity” setting. All our photos are taken with f2.8.
Shutter Speed: At least 15 seconds. All our pictures were made with 20.0sec.
Attention to your batteries! They don’t really appreciate the cold and get out of energy quite fast. Make sure to keep them warm as long as possible and just in case – to take a recharge battery. We had two cameras, so when one was out of battery, we could use another one.
