30sec EXP @ F22 ISO 100 - No Flash
Technique:
Camera mounted on tripod and set to 30sec exposure, with bonnet OPEN. Start the exposure (best done with remote), about 20secs into the exposure get someone to cover the lens with a piece of black card (or in my case a satnav leather wallet) while you quickly shut the bonnet, as soon as your out of the shot the lens needs uncovering for the remainder of the exposure.
