I tried developing a print in coffee once. It didn't work at all. I mixed up instant coffee at twice the reccomended dilution, printed a picture and put it in. I didnt' use baking soda, I just assumed it was used to make the soup less acidic. I didn't monitor the pH because it said the best pH was 9. I figured anything would work, but not be the best. It did not work at all. I didn't do any exposure compensation, used ilford multigrade RC paper. and left it in the coffee for over an hour.
Any suggestions to what could have gone wrong?
