Finally had a chance to ink up a couple of test prints. The first was overexposed but shows some good relief detail in the Bristlecone pine forest. I used an old digital negative made for platinum/palladium.
Next test was an abandoned cabin near Fairplay, Colorado. again, this was made with a digital neg made for Pt/Pd.
Here’s a closeup of the cabin with a ruler to give scale.
The inking was primarily done with a 4-inch foam roller. I then tried modifying local contrast with a 1-inch bromoil brush. I used Graphic Chemical 1496 Black Lithographic ink. The matrix soaked in 70-degree water for one hour before inking. The paper was made a week earlier with an 8% gelatin mix and poured using 0.035″ magnetic strips as a dam. The solution is leveled with a heated stainless steel rod.
