I know that it is a failure as a controlled test, if I change such a huge variable like is the paper from one test to the other it is not a valid test in an strict sense.
But it gives me a fair enough sense of what I can obtain with the other 2 variables: The coating and the negative.
So, lets start.
I’ve created three images from each negative: 1 without an coating, other with a coating of saline solution (from my sister’s first aid kit, she is a surgeon so have a lot of interesting stuff), and one with a variation of the formula presented by Joan Foncuberta in his book: “Photography Concepts and procedures. A methodological proposal”.
