Shoot INFRARED FLASH PHOTOGRAPHY with this excellent used Sunpak 622 Super Pro-System Flash with a modified 840nm IR Head, and a regular zoom head. So you can shoot regular flash and IR flash. The IR Head puts out a lot of power at 840 nanometers. I get about f/16 at 10 feet with ISO 400. Your exposure will depend upon your camera and how it was converted. (see sample photo taken with this set-up of people in costumes) LifePixel converted my camera to 830nm deep black and white infrared, which is one of their darkest filter conversions -- so you will probably get f/22 with other conversions. Use this set-up with your infrared converted digital camera, or a film camera with infrared film. When the flash goes off, all you see is a very very faint purplish glow that is hardly noticeable and lasts a fraction of a second. THIS IS VERY USEFUL FOR PHOTOGRAPHING EVENTS LIKE CONCERTS WHERE A FLASH WOULD ANNOY THE PERFORMERS. AND YOU CAN EVEN USE THIS SET-UP IN DAYLIGHT FOR INFRARED FLASH FILL. So if you photographed someone at a park -- the foliage would get that cool infrared look, and your subject would be illuminated with the infrared flash -- there are so many creative things you can accomplish! The flash takes 6 C size batteries (not included). Also included is a sync cord. Use the sync cord to trigger the flash, or you can attach a remote trigger. WHEN USING THE SYNC CORD - MAKE SURE TO USE A SOLD-SEPARATELY WEING-SAFE SYNC HOT SHOE TO HOT SHOE WITH PC -- this makes sure that if the trigger voltage on the Sunpak flash is too high for your camera, that the flash doesn't damage your camera circuitry.
