A Sunny 16 day
A recent summer Saturday was a Sunny 16 day – a glorious day to teach some location lighting (Sunny 16 = 100iso, 1/125, F16).
Our group spent a large part of that Saturday up on Photofusion’s roof in the heart of a very vibrant Brixton. On such a bright and sunny day the main thing to learn was how to under-expose the sky to make a really saturated blue. This isn’t too difficult to achieve but when your F-stop is 2.8 you end up with a shutter speed of around 1/4000.
This poses a real problem for flash synchronisation as ‘normally’ a DSLR camera cannot ‘sync’ with flash at shutter speeds beyond 1/200. So to ‘sync’ at 1/4000 we did it in two ways. We used Pocket Wizards wireless triggers with Hyper-sync on an Elinchrom Quadra battery pack and High Speed Sync with some Canon flashguns (they do the same but they do it differently – Hypersync uses some clever timing and HSS pulses the flash to simulate a continuous light source).
Regardless of which you use they both open up new possibilities for flash users and are indispensable on Sunny 16 days.
