Here’s a 3 sec long hand-held exposure that I shot in 2010. Photography was still new to me then and I was saving money to afford a Nikon D700 (which I bought later that year). Back then, this was the only DSLR that supported multiple exposure that I’d seen been experimented with on film by inspiring legends such as Harry Callahan and Charles Swedlund.
If you don’t know them, congratulations—you’ve just been handed a bag of pleasing eye candy from the middle 19th century.
