Many photographers like to experiment with long exposure photography techniques, but an Australian Lincoln Harrison gives a new definition to the word “long”. A 37-year-old Victorian showcases a portfolio of mesmerizing long exposure star trail photography, with some of his photo shoots taking up to 15 hours. The photos are made at his personal favorite spot over Lake Eppalock, in the Australian outback. The star swirls is the result of the rotation of the Earth, and makes you think you’re witnessing the stars traveling across the sky.
