Light is only visible when it strikes something. Alexander Harding’s "Visible Light"" series makes us see it in a whole new way.
Harding says: "When I make these pictures, I track light over several days and make
notes about its location at various times.I usually make drawings and
smaller digital pictures to get a general idea of what I want. Light
moves very fast so I have to be quick when making the final picture,
which is hard with an 8x10. I make very long exposures and sometimes
use steam or a fog machine to give the light a more discernable shape
in the registered image."
