This 7 minute video I found on Youtube gives a great explanation of this phenomenon.
The above was shot last year on our third shoot, this time, in the sun yes, I hate shooting models in the harsh midday sun — but we managed to pull this one off brilliantly with perfect placement of the shadows to create a glamour short-lit loop lighting effect.
That was several years ago now, and Sylph and I have now shot together a further two times.
On this shoot, I asked Sylph Sia, my muse for the day, to express this herself, neither of us realising that perhaps at that very moment her house was being invaded and she was robbed of all the material things she held dear as well as her personal life in her hard drives.
Nevertheless I still love his work.
This perhaps explains why many spend so much time on social media platforms, seeking out those dopamine hits.
