To get started you will need:

A camera with manual or bulb exposure control - to achieve the long shutter speeds necessary.
A sturdy tripod or sit your camera on a sturdy surface - the exposure will be measured in seconds so handholding is ruled out
A light source - this can be a wireless flash, torch, led tubes, anything that emits a bright light, the more variations in size and colour the better
Other useful items - a cable release, extra batteries
A dark place or scene - can be indoors or out

How to setup:

Decide on your shoot location and place your camera on the tripod or a sturdy surface
Switch your camera to manual mode and set your ISO to 100, a small aperture, such as f/11 or higher f number and shutter speed to between 10-30 seconds
Fix your white balance depending on your light source, try “incandescent” or “tungsten”
Your camera won’t focus in the dark so pre-focus on the area you wish to shoot, switching your lens to manual focus
If using a shutter release attach that now, alternatively use the 2 or 10 second timer to prevent camera shake when pressing the shutter
