These images were developed using coffee and hot water (no other ingredients were used).
For these pictures, I shot in low light using a Kentmere 400 Black an White film. Most images were shot around 1/60 at f/ 2.8.
After developing and scanning, the images were converted to black and white (as inverting the negative came out blue). No other post editing has been done at this stage to show as best as possible the sort of results coffee alone can give you.
