An ostrich egg pinhole camera. Inspired by Jeff Fletcher's Bromide Eggs series in 1989, where he imaged his pictographs onto the inner surface of opened egg shells, and Francesco Capponi's pinhegg series in 2011. I imaged a photograph of Woodworks, a woodturning and furniture restoration craft shop in Peebles, onto the inner surface.
The original (negative), left, and the final (inverted) positive, right. Exposure: 4 minutes at f/250
