Last week. It was actually a test of 6+ years old opened
MACO Lith concentrates that have been brewing (oxydizing) in my cellar while I was away from my country for some years. It is so wet in the cellar that all the labels of the bottles have peeled off! And 7+ years old opened package of MACO Lithpaper staying at room temperature. Didn't expect the chemistry and paper emulsion to work so good after all those years. I have some Moersch Lith stuff I want to try next.
Pentax 67, 105mm f2.4, Rollei 100 Tonal (developed in Diafine A+B), Durst 1200, Rodenstock 90mm F4 APO, MACO Superlith + MACO Lithpaper. Drumscanned with low-res just for web-use.
