Playing with the 250 sheets of Luminos VC RC paper I just got. Also started trying to formulate a lith developer at the same time with the advice of several people on the group here. The paper liths quite nicely. Reminds me of Kentmere Warmtone with its cool shadows and putty colored highlights. The developer was mixed just before use and it was 3g of Hydroquinone, 3g of Sodium sulfite, 1.5g of KBr and 60g of potassium carbonate per liter. I think it was a bit too strong, but it lasted the 8 prints I put through it and it was still going. It was starting to show pepper grain on the luminos and it was dark brown, but still going. Going to try to replenish it with some hydroquinone and sodium sulfite next time.
