ABSTRACT This workshop is an introduction to Studio Flash for still photography. At the end of the session attendees should be able to use any studio flash equipment once they have familiarised themselves with strange controls. In addition each photographer should have some ‘feel’ for the available effects in the studio The workshop is divided into sections: Understanding what happens in use and how to manage a flash head Focussing and feathered light Control boxes Light modifiers and accessories Managing light Special Heads Summary |

| SAFETY Modern studio flash varies enormously. There are small flash guns which can be used for low level close work up to very powerful lights. It has to be appreciated that a small head costing £10 is unlikely to be as powerful or effective as a studio head costing £1000 and needing a box costing £4000 to drive it. In essence all flash heads rely on charging a capacitor and then discharging it through a flash tube. The larger the capacitor and the higher the voltage the bigger the amount of light given. This immediately raises questions about safety and how one might control the energy. DO NOT DISASSEMBLE FLASH HEADS - EVEN WHEN THE BATTERIES ARE REMOVED THEY CAN BE LETHAL. RATINGS The practiced studio photographer will have a good idea about how much light is emitted by his various flash heads. To put this in perspective, we can use an ordinary flash meter to compare several different heads with each other and the performance compared to daylight. £10 Jessop battery head - manual f4 Make a note of the results found. The 400J Jessops head is adjustable for half or full power. BronColor heads are adjustable over more than 6 stops in steps of 1/10 of a stop. |
