Short tutorial giving brief explanation of how to film a series of high voltage discharges. Tesla coil used for disruptive discharges. Grounded mirror plate wired to outside RF ground. Super saturated NaCl + H2O solution and discharges to dry plate; greenish glow caused by Mg shavings. Macro lens setting, high ASA or shutter speed, manual focus locked in to avoid focus cycling, caused by rapid alternations in light intensity.
