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

 

 

Stay safe and healthy!
