The first three are of bridges in Iida-shi in Nagano prefecture, Japan, taken with a matchbox pinhole camera and a roll of Fuji Pro 160C. Hanne says she's been enjoying playing around with simple pinholes a lot this past year – that and long exposures.
The next one is a solargraph exposed for 4 1/2 months in a black plastic canister for 35 mm film, on Ilford Multigrade IV paper.
The final one was taken with Hanne's half-frame
Olympus PEN EE.S, which she finds fun to use from time to time.
