Nicephore Niepce

Historical update: the eight-hour exposure time was an assumption based on speculation about the shadows in the image. A researcher using methods and materials described by Niepce says the exposure time for this historic image was *several days.* Blimey! 😬

wouldn't the lack of light at night make this impossible? :-0

[@TheStockwell]

​@@g013zNo. What mattered was exposure to several days of sunlight - not that nighttime put the exposure "on hold." The exposure to sunlight was cumulative. Best wishes from Vermont 🍁
