Gallery 268: Time Flux Playing with light is always also playing with time. In this arty gallery I have given myself some longer time for motion ;-) The luminous exposure Hv is Ev t, where Ev is the illuminance and t is exposure time. Hv is directly proportional to t / k2, where k is the f-number of the lens. Using a longer exposure time with the same exposure Hv needs larger f-number (smaller aperture). In these images my shutter speed was 1/4s and in some images 1/2s with k = 5.6. That result in a EV value of 6-7. Err... nerding around Comments appreciated! ... please check the news page and write a comment in my guestbook! Costume: White shiny Zentai [NA], black shiny Zentai [NA] Camera: Nikon D300. Radio trigger for camera + flash. Lens: Sigma 10-20mm Lighting: Room light, LED floodlight |
