Hey all,
Planning on doing some experiments this weekend with my developer, Ultrafin, and to see what effects dilution has on contrast. I generally mix up 10ml of Ultrafin to 190ml of water and that's working fine for me. I planned to try 1/10 and 1/30 dilution but my concern is 6.666(666666 etc.) ml for 1/30 dilution of developer may not be enough. I'm developing a single sheet of 8x10 at a time. I could use a bit more water I suppose but my Paterson Orbital will only contain so much liquid before it spills over the top!
